长三角创新能力评价及其时空格局演化

Evaluation of Innovation Capacity of Yangtze River Delta and Analysis of its Spatial and Temporal Pattern

摘要:

选取长三角27市2000—2019年的面板数据,基于熵值法从5个维度对该区域进行创新能力评价及其时空演化分析。结果表明,长三角创新能力整体呈增长态势,随时间推移,创新技术能力逐渐取代创新基础环境成为影响创新能力的首要维度；从时间上可划分为快速、稳步和缓慢三个发展阶段,空间上东部热点城市数量逐渐增加；各城市按其创新能力差异可划分为微调首位型城市、波动中位型城市和平稳后位型城市,其中前两类城市均需将创新基础条件和创新技术能力作为提升城市创新能力的重要维度,平稳后位型城市则需将创新基础条件和产业集聚度列为重要维度。

Abstract:

The panel data of 27 cities in Yangtze River Delta from 2000-2019 were selected to evaluate the innovation capability of the region and its spatio-temporal evolution analysis based on the entropy value method from five dimensions. The results show that the innovation capability of the Yangtze River Delta as a whole is growing, and the innovation technology capability gradually replaces the innovation infrastructure environment as the primary dimension affecting the innovation capability over time; in terms of time, it can be divided into three stages of rapid, steady and slow development, and the number of eastern hotspot cities gradually increases spatially; according to the differences in innovation capability, cities can be divided into fine-tuned first cities, fluctuating middle cities and smooth back cities. The first two types of cities need to consider innovation infrastructure conditions and innovation technology capability as important dimensions to improve the innovation capability of cities, while the cities in the latter category need to consider innovation infrastructure conditions and industrial concentration as important dimensions.
