城市产业结构与绿色全要素生产率—基于东北地区的实证分析

Research on the Relationship between Urban Industrial Structure and Green Total Factor Productivity: An Empirical Study of Northeast China

摘要:

优化产业结构不断提升绿色全要素生产率是实现城市经济高质量发展的重要举措。以东北地区34个地级及以上城市为样本，运用计量经济模型分析了城市产业结构合理化、产业结构高级化、产业专业化集聚和产业多样化集聚与绿色全要素生产率的关系及其影响机制。研究结果表明：城市产业结构合理化对绿色全要素生产率的作用主要通过生产技术效率提升和投入偏向型技术进步实现；城市产业结构高级化通过技术效率提升和产出偏向型技术进步对绿色全要素生产率产生影响；城市产业专业化集聚对绿色全要素生产率的影响主要通过提升技术效率和中性技术进步实现；城市产业多样化集聚对绿色全要素生产率的作用受到技术效率、产出偏向型技术进步和中性技术进步中介效应的影响。

Abstract:

One of the important measures to realize the high-quality development of urban economy is to optimize the industrial structure and enhance the green total factor productivity (GTFP). Taking 34 central cities in Northeast China as samples, this paper uses econometric model to analyze the relationship between the rationalization of industrial structure, the advanced industrial structure, the industrial specialized cluster and the agglomeration of industrial diversification and the GTFP . The results show that: The effect of rationalization of industrial structure on GTFP is realized by improving technological efficiency and investment biased technological progress. The upgrading of industrial structure has an impact on GTFP through the improvement of technological efficiency and output biased technological progress. The industrial specialized cluster has an impact on GTFP by improving technological efficiency and neutral technological progress. The impact of agglomeration of industrial diversification on GTFP is related to the mediating effect of technological efficiency, output biased technological and neutral technological progress.
