摘要:

新质生产力代表了新一轮的产业变革和技术发展的方向,是推动实现中国式现代化的重要发力点。本文对2012—2021年中国236个地级市进行研究,通过修正引力模型构建出新质生产力空间关联网络,并采用社会网络分析法从整体网络、个体网络和“核心-边缘”角度对新质生产力空间关联网络进行研究,最后通过动态指数随机图模型分析了新质生产力空间关联网络的影响因素。结果发现:①在空间上,新质生产力空间联系强度的俱乐部效应显著,东部地区空间联系强度最高,而西部地区空间联系强度最低,同时随着时间推移,俱乐部效应趋于稳定。②从整体网络中发现,新质生产力空间关联网络发展稳定,网络中存在具有支配作用的重要节点;从个体网络中发现,直辖市、东部和中部省会城市的点度中心度和中介中心度较高,而西部和东北地区城市的接近中心度较高,能够与网络中其他城市快速建立联系。③通过“核心-边缘”分析发现,中部地区核心城市的聚集效应明显,且核心城市的整体变化不明显。④基于动态指数随机图分析发现,新质生产力空间关联网络同时受到内生效应、时间效应和外生效应的共同驱动,城市之间可以通过优势互补形成发展合力,并且低水平城市会积极地与高水平城市建立合作关系。

Abstract:

New quality productivity represents the direction of a new round of industrial transformation and technological development and is an important driving force for promoting the realization of Chinese modernization. This paper studies 236 prefecture-level cities in China from 2012 to 2021, constructs a spatial correlation network of new quality productivity through a modified gravity model, and uses social network analysis to study the spatial correlation network of new quality productivity from the perspectives of the overall network, individual network, and core edge. Finally, the dynamic exponential random graph model is used to analyze the factors affecting the spatial correlation network of new quality productivity. The results show that: ① In terms of space, the club effect of the spatial connection intensity of new quality productivity is obvious, with the highest spatial connection intensity in the eastern region and the lowest spatial connection intensity in the western region. At the same time, as time goes by, the club effect becomes more and more obvious and stable. ② From the overall network, it was found that the spatial correlation network of new quality productivity has developed stably, and there are important nodes with dominant role in the network; from the individual network, it was found that the point centrality and betweenness centrality of municipalities and provincial capitals in the east and central regions are relatively high, while the proximity centrality of cities in the west and northeastern regions is relatively high, and they can quickly establish connections with other cities in the network. ③ Through core-edge analysis, it is found that the agglomeration effect of core cities in the central region is obvious, and the overall change of core cities is not obvious. ④ Through dynamic index random graph analysis, it is found that the spatial correlation network of new quality productivity is driven by endogenous effects, time effects and exogenous effects at the same time. Cities can form a development synergy through complementary advantages, and low-level cities will actively establish cooperative relations with high-level cities.
