珠三角城市金融发展、科技创新对产业结构优化影响研究

Analysis on the Influence of Financial Development and Technological Innovation on Industrial Structure Optimization in the Cities of Pearl River Delta

文章基于珠三角9个城市2008-2019年的面板数据,构建基准回归模型、中介效应模型以及门槛效应模型,实证分析金融发展、科技创新对产业结构合理化和高度化的影响。研究结果表明:珠三角城市金融发展对产业结构高度化的提高已经取得显著成效,科技创新对产业结构合理化与高度化的提升既产生直接促进效果,又在金融发展促进产业结构高度化过程中发挥了中介效应;金融发展对产业结构高度化的提高存在金融发展的单门槛效应。为此,应遵循市场经济规律,健全市场金融运行制度;深化金融改革,构建多层次金融市场体系;以科技驱动金融创新,加快科技创新与金融的融合。

Based on the panel data of nine cities in the Pearl River Delta from 2008 to 2019,this paper constructs the benchmark regression model,the intermediary effect model and the threshold effect model,and empirically analyzes the impact of financial de⁃velopment and scientific and technological innovation on the rationalization and upgrading of industrial structure.The results show that the financial development of cities in the Pearl River Delta has achieved remarkable results in the upgrading of industrial struc⁃ture.Scientific and technological innovation not only directly promotes the rationalization and upgrading of industrial structure,but also plays an intermediary effect in the process of financial development promoting the upgrading of industrial structure.There is single threshold effect of financial development on the upgrading of industrial structure.Therefore,we should follow the law of mar⁃ket economy and perfect the system of market finance operation;deepen financial reform and build a multi-level financial market system.We should use science and technology to drive financial innovation and speed up the integration of innovative technology and finance.
