Abstract:

This paper builds urban supply network from the perspective of value chain. Based on the data of supply chain concentration in 2013, 2016, 2019 and 2022, this paper explores the spatial-temporal evolution characteristics and the influencing factors of manufacturing urban supply network by complex network research method. Following are the results: ① The development of the overall network tends to be balanced, the tightness and stability of the network are enhanced. The trade accessibility is improved, and it has a certain "small world", but this nature is being gradually broken. ② The eastern region is in the core leading position in the network, the central and western regions are in the periphery of the network as a whole. The capital cities of the central and western regions become important "bridges" connecting the east, central and western regions. ③ The supply network of the manufacturing industry initially forms a "rhombus-like" supply pattern with the four major urban agglomerations of Beijing-Tianjin-Hebei, Yangtze River Delta, Guangdong-Hong Kong-Macao and Chengdu-Chongqing as the apex. After the pattern is weakened, it is further highlighted and develops into a "T-shaped" pattern. The network presents a complicated evolution process, and appears the characteristics of "east-leading - central catch-up-east-central-western linkage development". ④ Degree of openness to the outside world, potential of market development, optimization of industrial structure, level of economic development and spatial geographical distance are the main influencing factors in the evolution of manufacturing supply network pattern, and the influence of urban geographical location is gradually weakening.

摘要:

本文以制造业为例从价值链视角构建城市供应网络,基于2013年、2016年、2019年和2022年供应链集中度数据,运用复杂网络等分析方法,探究中国制造业供应网络的时空演化特征及影响机制。研究发现:①整体网络发展趋向均衡化,网络紧密性、稳定性逐步增强,贸易通达性提高,具有一定的“小世界”特性,但该性质正在被逐步打破。②东部地区在网络中处于核心主导地位,中、西部地区整体处于网络的边缘位置,中西部地区的省会城市成为连接东、中、西部的重要桥梁。③我国制造业城市供应网络初始形成以京津冀、长三角、粤港澳、成渝四大城市群为顶点的“类菱形”供应格局,该格局先被削弱后又进一步凸显,并向“丁字形”格局发展;网络呈现复杂化的演化过程,出现“东部领衔-中部追赶-东中西部联动式发展”的特征。④对外开放程度、市场发展潜力、产业结构优化、经济发展水平及地理空间距离是制造业供应网络格局演化的主要因素,但地理空间距离的影响力逐渐减弱。
