In order to promote high-quality growth, China's mass entrepreneurship and innovation policy, which encourages the development of enterprises, faces the dilemma of short survival period of firms. First of all, reviewed the relevant literature, this paper puts forward the hypothesis that the size and productivity of firms have a positive impact on the market survival rate of enterprises, and both of them show nonlinear characteristics, in which the impact of the former is gradually decreasing, and the impact of the latter is gradually increasing. Next, based on the sample data of Chinese manufacturing firms, this paper uses statistical description, Kaplan Meier survival curve, Cox proportional risk regression analysis and other methods to verify the research hypothesis. The results show that: the survival of firm is significantly distributed to the right, and the average life is short; the K-M survival curve of firm size and productivity shows that they can positively affect the survival of firms; and The deposit analysis further verifies the nonlinear relationship between variables and its specific characteristics; the analysis of other control variables shows that the heterogeneity of firms, such as capital intensity, ownership and regional differences, also affect the survival of firms. Finally, this paper concludes with two implications: first, industrial policy needs to pay attention to the size, productivity and market survival of firms and the relationship between them, as well as the measurement of the size of firms, as a key indicator of resource tilt; second, the investment decision-making of firms should not only make adaptive adjustments from the perspective of size and productivity, but also pay attention to the degree of capital intensity, the nature of ownership and the impact of regional differences.
