区域产业协调政策的创新效应——来自长三角G60科创走廊的证据

The Innovative Effects of Regional Industrial Coordination Policies:Evidences from the G60 S&T Innovation Valley of Yangtze River Delta

为深度评估区域产业协调政策带来的创新效应及其对技术市场一体化的影响,文章基于长三角三省一市上市公司数据和城市间专利转让数据,采用双重差分方法,以长三角G60科创走廊设立作为准自然实验展开实证研究。实证结果发现,G60科创走廊及其所带来的一系列相关政策措施有效提升了企业的创新投入和创新产出水平。机制研究表明,这一政策促进了城市间创新要素的流动、缓解了企业融资约束、提高了行业市场竞争水平,这些都为企业提供了优良的创新环境,从而促进企业创新。进一步讨论说明,G60科创走廊的设立也促进了成员城市之间创新成果的交易与转化。

To deeply assess the innovative effects brought by regional industrial coordination policies and their impact on the integration of the technology market,the article,based on the data from listed companies in the three provinces and one municipality of the Yangtze River Delta and the inter-city patent transfer data,conducts an empirical study with the establishment of the G60 S&T Innovation Valley of Yangtze River Delta as a quasi-natural experiment using the differences-in-differences method.The empirical result shows that the G60 S&T Innovation Valley and the series of associated policy measures it brought have effectively enhanced the level of innovation input and output of enterprises.The mechanism research shows that this policy promotes the flow of innovation elements between cities,alleviates corporate financing constraints,and improves the level of market competition in the industry.All these provide an excellent innovation environment for enterprises,thereby boosting the corporate innovation.Further discussion indicates that the establishment of the G60 S&T Innovation Valley has also promoted the trading and transformation of innovation achievements among member cities.
