自由贸易试验区对企业创新的异质性影响研究

Research on the Heterogeneous Impact of Pilot Free Trade Zones on Enterprise Innovation

自贸区的设定对企业创新有一定的积极作用,文章从微观企业本身视角,利用2010-2020年中国沪深A股上市公司及省级面板数据,采用双重差分模型实证考察了自由贸易试验区的设立对企业创新的影响效应及作用机制,对自由贸易试验区设立与微观企业创新行为间的因果关系进行系统探究与充分论证。

The establishment of free trade zones has a certain positive effect on enterprise innovation.This article,from the perspective of micro enterprises themselves,uses panel data of A-share listed companies and provincial-level companies in Shanghai and Shenzhen from 2010 to 2020,and uses a double difference model to empirically examine the impact and mechanism of the establishment of free trade pilot zones on enterprise innovation.The causal relationship between the establishment of free trade pilot zones and micro enterprise innovation behavior is systematically explored and fully demonstrated.
