Abstract

Technological progress, especially green innovation, is a key factor in achieving sustainable development and promoting economic growth. In this study, based on innovation value chain theory, we employ the location entropy, super-efficiency SBM-DEA model, and the improved entropy TOPSIS method to measure the technological industry agglomeration, two-stage green innovation efficiency, and development quality index in Yangtze River Delta city cluster, respectively. We then build a spatial panel simultaneous cubic equation model, focusing on the interaction effects among the three factors. The findings indicate: (1) There are significant spatial links between the technological industry agglomeration, green innovation efficiency, and development quality in city cluster. (2) The development quality and technological industry agglomeration are mutually beneficial. In the R&D stage, green innovation efficiency, development quality, and technological industry agglomeration compete with each other, while there is a mutual promotion in the transformation stage. (3) The spatial interaction among the three factors reveals the heterogeneity of two innovation stages. The positive geographical spillover effects of technological industry agglomeration, green innovation efficiency, and development quality are all related to each other. This paper can provide a reference for the direction and path of improving the development quality of city clusters worldwide.

科技产业集聚、绿色创新效率与城市群发展质量

技术进步，特别是绿色创新，是实现可持续发展和促进经济增长的关键因素。本文基于创新价值链理论，采用区位熵、超效率SBM-DEA模型和改进熵TOPSIS方法，分别对长三角城市群的科技产业集聚、两阶段绿色创新效率和发展质量指标进行测度。在此基础上，建立了空间面板联立三次方程模型，重点研究了三者之间的交互效应。研究结果表明:(1)科技产业集聚、绿色创新效率与城市群发展质量之间存在显著的空间联系。(2)发展质量与技术产业集聚是互惠互利的。在研发阶段，绿色创新效率、发展质量、技术产业集聚三者相互竞争，在转型阶段，三者相互促进。(3)三要素间的空间交互作用揭示了两个创新阶段的异质性。技术产业集聚、绿色创新效率和发展质量的正向地理溢出效应相互关联。本文可为世界范围内提高城市群发展质量的方向和路径提供参考。
