Objectives: Since the China Securities Regulatory Commission (CSRC) issued the Measures for the Administration of Equity Incentives of Listed Companies, the equity incentives of A-share listed companies have become normalized, the discussion of the effect of the implementation of
equity incentives on stock valuation can provide a reference for investors whether to choose listed companies with equity incentives for stock valuation. This paper uses python tool to select 30 A-share listed companies that formally started to implement equity incentives in 2018 and the proportion
of equity incentives is between 4% and 6% as the sample, and uses cross-sectional data model for empirical analysis. The empirical results show that: first, the implementation of equity incentive in Chinese listed companies has a positive impact on stock valuation, and the impact of equity
incentive on stock valuation is significantly better than that before implementation, and the incentive stocks have more investment value; Second, the conclusion is also suitable for Chinese tobacco related companies, which has important reference value for tobacco preference investors.
