Study on spatio-temporal evolution of terrorist attacks in South America Yukun SHEN, Huasong LUO, Juhua HONG, Lu ZHANG 2021, 30(1): 12-24.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019304 Abstract ( )   HTML ( )   PDF (2462KB) ( )   The spatial-temporal evolution of the 1970-2017 South American terrorist attacks was analyzed by using Kernel Density Estimation and gravity center analysis methods. The results show that: the years 1980-1989 and 1990-1999, were the periods of the high incidence of terrorist attacks in South America; the difference in spatial distribution of South American terrorist attacks was significant. From 1970-1979, they were mainly concentrated in Colombia and Argentina, while the high incidence was mainly concentrated in Colombia, Peru and Chile. Since 2000, it has been mainly concentrated in Colombia. In recent years, terrorist attacks in Venezuela and Paraguay have also risen. The spatio-temporal evolution of terrorist attacks in South America is the result of multiple factors including geographical environment, geopolitical, economic and social environment, drug trade, government's coping strategies and social control system, easy access to weapons, border control, etc. Based on the above conclusions and the need to safeguard China's interests in South America, This study suggests that China should strengthen its counter-terrorism cooperation with South American countries. Inspired by the cross-border infiltration of South American terrorist attacks and the phenomenon of "Terrorism and Drug Combined", This study suggests that China should be alert to the infiltration of terrorist attacks in Southeast Asia and the possibility of the "Terrorism and Drug Combined".

The community structure and its economic convergence effect of merchandise trade network in the "Belt and Road Initiative" area Peiyu WANG, Ye WEI, Xin GAO 2021, 30(1): 25-36.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019363 Abstract ( )   HTML ( )   PDF (1774KB) ( )   Based on per capita GDP panel data of each country from 2003 to 2017, Beta convergence model supported by neoclassical growth theory is applied to test the convergence hypotheses.The research reveals that:Density of the merchandise trade network in the "Belt and Road Initiative" area has been increasing, forming a cross-regional trade cooperation system.The evolution of communities in merchandise trade network was relatively stable over the past 15 years.Since 2013, the number of countries in Southeast Asian-West Asian community has soared, covering almost all Asian countries included in the "Belt and Road initiative" area.European countries have close internal links with each other and form regional trade cooperation system, while they are not fully integrated into trade network in the "Belt and Road initiative" area.Trade links play a significant role in reducing the economic growth difference between countries.The world financial crisis speeded up the convergence rate in trade communities and promoted the process of regional integration.During the whole research period, the economic growth of countries along the Belt and Road supported convergence hypotheses. The convergence rates of trade communities were higher than that of overall trade network. Especially, the China-centered Southeast Asian-West Asian community has shown convergence trend in all the three periods. Figures and Tables | References | Related Articles | Metrics

The challenges of spatial planning in Indonesia under the background of local autonomy Juwita Melda Ria, Tao WANG, Xinyang JIANG, Supriyadi Agus 2021, 30(1): 48-56.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019357 Abstract ( )   HTML ( )   PDF (946KB) ( )   Spatial planning assists the governance of national political, economic and social affairs by coordinating regional activities and making rational use of space. Spatial plan in Indonesia, formulated and implemented by the President, embodies the country's political vision and tasks. When the governance structure changes, the spatial planning of each region and its specific implementation procedures also change. Decentralization and local autonomy are big-bang changes for the Indonesian government system. Since the local autonomy system has been implemented, Indonesia's spatial planning has begun to face quite complex challenges. Based on a qualitative descriptive method and the adoption of a systematic literature review method to explore the challenges of local autonomy in spatial planning, the study analyzed the historical phase of local autonomy and spatial planning in Indonesia, and point out spatial planning problems in the local autonomy situation. It shows that problems such as lack of funds to start spatial planning for autonomous regions, lack of qualified human resources, the presence of regional egoism and frequent violations in the implementation of regional spatial planning can be overcome by sharpening the ability of government officials to manage local policies and enforce laws. Besides, local autonomy has a certain impact on space planning: First, in the context of local autonomy, local governments increase regional revenue through systematic management to support the implementation of space planning. Second, local governments began to give priority to hiring professionals in space planning to develop more effective space planning policies. Finally, each region has strengthened the enforcement of space planning violators and enhanced the sense of solidarity among regions, thus promoting regional prosperity and development. At present, there are still a lot of conflicts in the distribution of power and interests between the central government and local governments. Therefore, the communication and cooperation between the higher and lower levels of governments should be strengthened to ensure the participation right of local governments in decision-making on local affairs, establish a mechanism for the expression and balance of local interests, and then improve the scientific and democratic level of central decision-making.

A comparative analysis of the intercity passenger transport network structure of three urban agglomerations in the Yangtze River Economic Belt Jianjun TU, Kai MAO, Renrui KUANG, Nanxi LI 2021, 30(1): 69-79.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019716 Abstract ( )   HTML ( )   PDF (1713KB) ( )   Space Flow is an important issue of human-economic geography.This paper uses spatial analysis, urban connection intensity model and other methods to describe the structural characteristics of the intercity connection network of the Yangtze River Delta, the middle reaches of the Yangtze River, and Chengdu-Chongqing Urban Agglomeration based on the data of traffic flow.Results are as follows: 1) The intercity network of the Yangtze River Delta urban agglomerations is mainly composed of Shanghai, followed by Suzhou, Nanjing and Hangzhou, but the connection between the west and south is relatively weak.Intercity network of urban agglomeration in the middle reaches of the Yangtze River takes three provincial capitals of Wuhan, Changsha and Nanchang as the core nodes. The surrounding sub central cities are closely connected with their provincial capitals, but the connection between cities is weak.Moreover, the provincial cities only have prominent centripetal connection with other capitals.Most of the high-level contact networks of Chengdu Chongqing urban agglomerations point to the main urban areas of Chengdu and Chongqing, and the sub regional central cities are underdeveloped.The main line of Chengdu Chongqing urban agglomerations is developed and shaped under the promotion of strong traffic links, However, there are few intercity connections between provincial fringe. 2) Three major urban agglomerations in the Yangtze River Economic Belt conform to the basic evolution trend of "level network".For example, Chengdu Chongqing urban agglomeration and the urban agglomeration in the middle reaches of the Yangtze River are still in the "core edge" dual core or three core structure, and the Yangtze River Delta urban agglomeration has appeared trend of multi-core network development.3) The emerging factor flows such as high-speed railway have obvious substitution effect on the traditional factor flows dominated by highway and common railway,which enhance the axis connection of core cities, becomes a new driving force for evolution of intercity connection network structure of urban agglomerations.

Literature analysis and hotspot change of urbanization research in Central Asia Haitao MA, Zhan SUN, Fangfang ZHANG 2021, 30(1): 80-89.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019387 Abstract ( )   HTML ( )   PDF (1581KB) ( )   Central Asia has a very important influence in the global network of contacts with its unique geographical location, rich resource endowments and complex political conditions. The urbanization process of Central Asian countries has always been the focus of international scholars. By searching for documents related to urbanization in Central Asia between 1980 and 2017 using SCI and CNKI databases as data sources, this paper analyzes the process and research hotspots of urbanization in Central Asia from multiple perspectives through bibliometric. The results show that: (1) The number of studies on Urbanization in Central Asia by domestic and foreign journals has increased rapidly. International journals research on Urbanization in Central Asia is mostly concentrated in developed countries and institutions in Europe and America and the research of domestic journals is mainly concentrated in universities and scientific research institutions in Xinjiang. (2) International research on urbanization in Central Asia can be divided into four stages. The hot keywords at different stages are life and health problems, resource development and environmental problems, industry and pollution problems, international cooperation and population migration. Among them, environmental health problem is the core issue of perennial concern. (3) The study of urbanization in Central Asia started late in domestic journals. During 2000-2009, domestic journals focused on energy cooperation and during 2010-2017, domestic journals have begun to pay full attention to the pluralistic cooperation of politics, economy, society and transportation. Among them, energy cooperation is the focus of long-term concern. "The belt and one road" has become the focus of recent research. (4) Generally speaking, domestic and international attention to urbanization in Central Asia is relatively wide, and the focus on urbanization is not enough. Globalization and the study of Central Asian urbanization under the background of "One Belt and One Road" has become a new hot spot of research.Key words: Silk Road Economic Belt; Central Asia; urbanization; research hotspots; bibliometric method Figures and Tables | References | Related Articles | Metrics

Characterizing the coordination and disequilibrium pattern of urban population, economics and urban built-up area in Eastern and Mid-China region Kehao ZHOU, Ronghui TAN 2021, 30(1): 90-100.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019400 Abstract ( )   HTML ( )   PDF (1745KB) ( )   Based on statistic and land use dataset of 261 prefectural cities in Eastern and Mid-China region in China from 2000 to 2015, this paper analyzed the spatial agglomeration and disequilibrium pattern change of urban population, GDP and urban built-up area and revealed the coordination degree between population urbanization rate and land urbanization rate by using spatial autocorrelation model, variation coefficient and the coupling model of three factors. The results show that: (1) the Moran's I value of urban population, GDP and construction land are all positive and the value in 2015 are larger than the value in 2000, implying an increased tendency of spatial cluster pattern from 2000 to 2015; (2) the variation coefficient of urban population and GDP per capita decreased from 1.38 and 0.91 in 2000 to 0.96 and 0.70 in 2015 respectively, while GDP per land increased from 1.32 to 1.77, which indicates the difference of urban population density and GDP per capita decreased but the difference of GDP per land increased in the same period; (3) the elastic coefficient of urban land increasing scale of 171 prefectural cities are lower than 1.12 and urban land per capita are lower than 115m2,which shows that land urbanization rate and scale are reasonable and can be controlled for most of cities, but economic outputs of urban land are still relatively low; (4) urban population, GDP and urban land are harmonious in both time spans for more than 90% of the prefectural cities. This paper will provide references and bases for formulating ordered, reasonable and balanced policies on the development and utilization of national land space, as well as solving urban spatial pattern optimization problems.

Analysis on the spatial structure characteristics and influencing factors of China's Green Financial Network: From the perspective of enterprise-city network retranslation model Yujie LI, Liming XIAO 2021, 30(1): 101-113.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019314 Abstract ( )   HTML ( )   PDF (2194KB) ( )   It is of great significance for the green transformation and high-quality development of regional economy to explore the spatial structure characteristics and influencing factors of green financial network. Based on the data of the headquarters and branches of enterprises, this paper constructs the enterprise-city network retranslation model, and investigates the spatial structure characteristics and influencing factors of China's green financial network with the help of social network analysis. The results show that: ① The overall density of China's green financial network is relatively low, which is showed by a "diamond" spatial structure with "Beijing Shanghai Shenzhen Chongqing" as the vertex. The network connection mainly occurs in the three hub areas, and the overall performance is "intensive in the East and sparse in the west". ② The core edge structure of individual network is significant, and only a few cities occupy an important intermediary position. ③ The level of urban administration, the location of enterprise headquarters, the proximity of space, the difference in fixed asset investment and the difference in the level of opening to the outside world have significant influence on the correlation of China's green financial network.

The network structure and influencing factors of the tourist flow within the city: The case of Shanghai Qian LI, Lingyan QU 2021, 30(1): 114-124.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019344 Abstract ( )   HTML ( )   PDF (1235KB) ( )   The current studies on the influencing factors of the tourist flow network are more focused on the regional scale, thus Shanghai is taken as an example. Taking domestic tourists who traveled to Shanghai independently as study object and expanding the selection of the tourist nodes, this thesis extracted digital footprint of Shanghai independent travel itinerary during the year 2018 from online travel notes with data mining. Using social network analysis to construct the directed network, the study analyzed the network structure of Shanghai tourist flow. The influencing factors were analyzed through regression model. It is suggested that (1) the network density is quite low, forming a significant core-peripheral structure, and the core zone's effect on the periphery zone needs to be strengthened; (2) the core tourism nodes are the traditional well-known tourist attractions in the downtown area and the Shanghai Disneyland; (3) the influencing factors of the importance of tourism nodes in the network are the influence of the core nodes, the popularity of tourism nodes and the convenience of transportation. Based on these findings, the thesis could guide tourism nodes to strengthen their status in the network or to help them merge into the network.

The role transition and potential benefits of overseas urban agriculture and its implications for China Enpu MA, Jianming CAI, Jing LIN, Liuwen LIAO, Yan HAN 2021, 30(1): 136-147.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019415 Abstract ( )   HTML ( )   PDF (1246KB) ( )   As a new form of agriculture, urban agriculture is essentially an urban ecological engineering with the direct purpose of food production, which is expected to make a positive contribution to the sustainable development of cities. In such a context, this paper first reviews the development process of overseas urban agriculture from a historical perspective, and then discusses the potential benefits of urban agriculture in the three dimensions of environment, society and economy based on literature evidence. Taking the green city project in Tel Aviv as an example, it analyzes the concrete performance of multi-functional benefits of urban agriculture. Based on that, the paper further points out that China still has many technological gaps in the development of urban agriculture. In order to meet the possible challenges of the urbanization century and narrow the gap between China and the rest of the world in urban agricultural development, China should take actions in establishing technical regulations and standards system, improving planning and implementation level, promoting the development and application of urban agricultural equipment and strengthening multidisciplinary technology integration as early as possible.

Study on spatial pattern evolution and location of the world cruise ship construction industry Ruru FANG, Renfeng MA, Baoyu ZHU, Pengchao XIE 2021, 30(1): 148-156.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019578 Abstract ( )   HTML ( )   PDF (1185KB) ( )   From macro point of view, spatial and temporal pattern evolution of the world cruise tourism can not only reveal the characteristics of cruise tourism space Organization, but also provide reference for cruise tourism in post-sending countries and regions. Spatial analysis and center of gravity model was used to analyze the spatiotemporal evolution and location characteristics of the world cruise ship construction industry. The fingdings are as follows: The center of gravity of the world cruise construction has not changed significantly from North America to Europe, and the higher economic density, the elimination of trade barriers to political and economic integration, and the "boundary effect" weakening is the main reason. The cruise brand agglomeration depends on the accumulation of local knowledge history, and the system. Based on the analysis of the histories of world cruise construction and tourism, domestic cruise construction industry should focus on investment and financial risks, industrial chain building, engineering management system construction and cruise construction talent cultivation, etc. The development path of "cooperation with Europe-China-EU co-construction-independent innovation" are relatively secure initiatives.

Access to homeownership in urban China from the perspective of intergenerational transmission: A case study of Shanghai Can CUI, Junru CUI, Jiayi LI 2021, 30(1): 167-178.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019564 Abstract ( )   HTML ( )   PDF (1137KB) ( )   With the rapid rise in housing prices in urban China, housing affordability has become a challenge for the younger generation. Although emerging studies have paid attention to housing inequality in China, most of them focused on the transistion of housing resource allocation from the state to the market. However, the role of family in housing acquisition is relatively neglected. Using 2013 Fudan Yangtze River Delta Social Transformation Survey (FYRST), this paper investigates the impact of housing assets and socioeconomic status of parents on housing acquisition of young families, paying particular attention to the differences between the impact of husband's parents and wife's parents. It has been found that parents' hukou status largely determines the position of young families in the housing market. The amount of housing wealth owned by parents with different hukou status varies remarkable, which affects the intergenerational support that their children could receive. Compared with wife's parents, the hukou status of husband's parents exert a greater impact on housing outcomes of young families. Wife's parents owing a home in Shanghai increases the probability of young families achieving homeownership. The intergenerational transmission of resources together with assortative mating through marriage will lead to the accumulation of housing advantages as well as disadvantages among young families, and may exacerbate housing differentiation within the young generation.

Difference in and determinants of subjective well-being for Chinese urban and rural residents Chudan GU, Fenglong WANG, Feng LUO 2021, 30(1): 179-191.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019690 Abstract ( )   HTML ( )   PDF (1053KB) ( )   In the Shanghai World Expo in 2010, it was proposed that "city makes life better". However, the empirical studies provide mixed and even dividing evidences. This paper argues that it is not city itself but better city that makes our lives more satisfied. Therefore, we investigate the patterns and determinants of subjective well-being for Chinese urban and rural residents based on the 2014 China Laborforce Dynamic Survey. It is shows that Chinese urbanites generally have higher level of life satisfaction than their rural counterparts. The results of multilevel regression model indicate that the urban-rural divide of life satisfaction in China mainly attributes to the differences in their living standards, residential environment and routine activities. Based on these findings, we suggest to improve the sense of gain for urban and rural residents, accelerate the integration of urban and rural public services, promote the reform of urban housing policies, explore the model of urbanization in the unit of family rather than individuals, and implement more sound labor policy in order to increase residents' life satisfaction in urban and rural China.

Does economic development narrow the supply gap of basic medical and health resources among regions? Shuting JIN, Bo LI, Yongchun YANG 2021, 30(1): 192-203.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019305 Abstract ( )   HTML ( )   PDF (1466KB) ( )   This paper analyzes the relationship of basic medical health resources supply differences and per capita GDP differences between underdeveloped cities and developed cities in China from 2000 to 2016. Based on lagged adjusted panel data model, we analyze the convergence of per capita GDP, and the convergence of the changes on basic medical health resources supply level with per capita GDP in 287 prefecture-level cities of China. Our findings are as follows:(1)From 2000 to 2016, there is absolute β convergence of per capita GDP among Chinese cities, and the economic convergence rate begin to decline after 2008;(2)The overall basic medical health resources supply gap between underdeveloped cities and developed cities is remarkably convergent. After the new healthcare reform, the convergence rate is accelerating, but the convergence speed is still much slower than that of per capita GDP;(3)There is absolute β convergence in the economic development of large, medium and small cities. Before the new healthcare reform, basic medical health resources supply differences between underdeveloped and developed medium-sized cities shows a decentralized trend along with the economic convergence. However, basic medical health resources supply gap of large, medium and small cities is converging after the new healthcare reform, and the convergence speed of the large-sized cities is declining;(4)The urban economic development of the four regions has absolute β convergence. Basic medical health resources supply gap between cities in eastern and central regions has been significantly converging, and it shows an accelerating trend after the new medical reform. However, there is a decentralized trend in basic medical health resources supply gap between Western and Northeastern regions and the rate has declined after the new healthcare reform.

Characteristic of positive and negative terrains and its effect on population distribution in the mountainous area, Guizhou Plateau Ya LUO, Jianhong YANG, Qiuwen ZHOU, Xu ZHOU, Jiusheng ZHONG, Xinyue HU, Qiyun GAO 2021, 30(1): 204-212.  DOI: 10.3969/j.issn.1004-9479.2021.01.2018465 Abstract ( )   HTML ( )   PDF (1535KB) ( )   Positive and negative terrains can redistribute water and soil resources through source-sink processes, which affect the population distribution in mountainous area, and need to be further studied. This study obtains positive and negative terrains data, applies six indicators and stepwise multiple regression method, analyzes characteristic of positive and negative terrains and their effect on population distribution in the mountainous area, Guizhou Plateau.Results indicate that: 1) Heterogeneity of positive and negative terrains is obvious.The average nibble degree (ND), cutting depth (CD), mean- roughness- ratio (MRR), shape index (SI), homogeneous index (HI) and fragmentation (F) are 1.07, 371m, 1.01, 3.40, 325 and 3.34, respectively.The positive terrain is nibbled obviously and cut deeply by the negative terrain, positive terrain is basically the same roughness as negative terrain, and landscape patches in positive and negative terrains are fragmented and showed irregular shape and uneven area. HI has the highest variability with the variation coefficient of 90.43%, and MRR has the lowest variability with the variation coefficient of 1.06%.2) The population distribution shows obvious inhomogeneity.When the cumulative percentage of population reaches 40%,cumulative percentage of area is 14%;when cumulative percentage of population reaches 80%, cumulative percentage of area is nearly 50%; the remaining 50% of the area accumulates only about 20% of the population.3)ND and CD are major factors affecting the population distribution.ND determines the population agglomeration level by affecting the land carrying capacity, and has a positive correlation with population density.CD determines population's agglomeration level by affecting the geological hazard risk of human settlement, and has a negatively correlated with population density.Findings can expand research on impact of terrain on population, and provide reference for coordinating man-land relationship and achieving sustainable land management in the mountainous area, Guizhou Plateau.

Study on spatial differentiation of population aging and mismatch of endowment resources in Xining City Xiaofan MA, Haifeng ZHANG, Ziyi GAO, Ao SUN 2021, 30(1): 213-222.  DOI: 10.3969/j.issn.1004-9479.2021.01.2019516 Abstract ( )   PDF (1695KB) ( )   Under the Healthy China strategy, It has become a concern of many city governments to actively cope with aging of population and establish facilities for the elderly people and medical care. At present, the relevant researches for northwest cities have not paid attention to spatial differentiation of population aging and mismatch of endowment resources. Based on the population data of the streets and towns of Xining municipal public security bureau from 2010 to 2018 and the data of point of interest (POI), taking the district as the basic unit, using the aging population coefficient, the elderly population support rate, the rate of the growth proportion and tempo of elderly geographical concentration of elderly population, taking CAI and the methods of kernel density estimation, spatial mismatch index to analyzes the spatial differentiation of population aging and the spatial mismatch of endowment resources (medical resources, the facilities for elderly people) and the spatial distribution of the aged population in the main urban area of Xining city. The results show that: (1) The aging of the population in Xining's main urban areas is deepening, and it has entered the aging society in 2010 to 2018. (2) The result of CAI can be known that the population aging growth rate of peripheral district has exceeded that of central streets. The aging phenomenon is the more serious in Xiaoqiao district, Chaoyang district, Mafang district and Lejiawan district than the district of downtown, The population aging of main urban area of Xining has spread from central district to the outer edge of a particular district. (3) The result of SMI can be known that there is a large spatial mismatch between the endowment resources and the distribution of the aged population in the urban area and the northern area of the city. How to reconcile the contradiction between the supply and demand of the endowment resources and the spatial distribution of the aged population has become one of the urgent problems to be solved by the municipal government.
