我国半导体显示产业财政补贴税收优惠对全要素生产率影响研究

Research on Effect of Government Expenditure Policy to TFP Enhancement of Semiconductor Display Industry in China

本文采用2010—2019年我国半导体显示产业上市公司数据对我国半导体显示产业全要素生产率进行测算,并分析了财政补贴和税收优惠对我国半导体显示产业全要素生产率影响的异质性。结果显示,我国半导体显示产业上游和中游企业全要素生产率具有明显异质性,上游企业十年平均TFP为1.64,中游企业十年平均TFP为1.78;财政补贴和税收优惠对半导体显示产业全要素生产率的影响具有明显的异质性,财政补贴抑制了全要素生产率的提高,而税收优惠促进了全要素生产率的提高。

This paper researches on government subsidy and tax preferences effect on TFP of semiconductor display industry in China.Calculated the TFP value of Chinese semiconductor display industry with the quoted company data from 2010 to 2019.Analysed the real impact on TFP from government subsidy and tax preferences.The result shows that the government subsidy suppressed the TFP of Chinese semiconductor display industry but tax preferences enhanced.This study provides policy reference for improving the TFP of China’s semiconductor industry,and has certain reference significance for the development of other high-tech industries and the formulation of industrial policies in China.
