Abstract
A sample of the annual data for A-share listed companies in China between 2010 and 2018 were used in this paper to explore the relationship between the native place of the chairman and company innovation with using multiple models for the solution of selection bias. The results of multiple models all led to the following consistent conclusion: When the chairman's native place was the same as the place of incorporation of the company, the company innovation capabilities as measured with indicators, such as patent numbers, R&D personnel numbers and R&D investment proportions, were all impaired. The results were consistent with multiple models that included the treatment effects model and the endogenous switching regression model. The same conclusions hold after further analyses of the subsequent treatment effects on the experimental group and the control group.
