区域市场化、技术创新与长江经济带产业升级

Regional Marketization,Technological Innovation and Industrial Upgrading in the Yangtze River Economic Belt

市场化通过优化资源配置对产业发展产生作用,技术创新通过导入一种新的生产函数推动产业结构升级,区域市场化和技术创新相协同对产业结构的合理化和高度化起促进作用。依据多个指标从五个方面构建了长江经济带108个地级市2007-2016年的市场化指数和区域创新度,采用两阶段最小二乘法分析区域市场化程度和技术创新对产业结构合理化与高度化的影响。结果表明,区域市场化和技术创新对产业结构合理化与高度化均具有显著促进作用,但存在倒“U”型关系;分地区来看,城市群的区域市场化和技术创新对产业结构合理化与高度化均有显著促进作用,城市群以外城市仅技术创新对产业结构合理化与高度化的促进作用显著。

Marketization plays a role in industrial development by optimizing resource allocation, and technological innovation promotes the upgrade of industrial structure by introducing a new production function. Regional marketization level and regional technological innovation are synergistic which promote the rationalization and upgrading of industrial structure. Based on several indicators, this paper constructs the market index and regional innovation degree of 108 prefecture - level cities in the Yangtze River Economic Zone from 2007 to 2016 from five aspects, and uses two - stage least squares method to analyze the impact of Regional Marketization Degree and technological innovation on the rationalization and heightening of industrial structure. The results show that both regional marketization and technological innovation have significant promoting effects on the “two - tions”,but there is an inverted “U” relationship. From different regional perspectives, the level of regional marketization and technological innovation in urban agglomerations have significant promoting effects on the “two - tions”. In cities outside urban agglomerations, only technological innovation has significant promoting effects on the “two -tions”. Based on this, relevant policy recommendations are put forward.
