Abstract
This paper is based on the Input-Output of 56 industries in 43 countries and China Industrial Enterprise Database. The identification of intermediate and final goods is carried out by using the ISIC industry codes from the World Input-Output Tables and the HS 8-digit product codes from the Chinese customs database, and finally the corresponding upstream degree index of industrial enterprises is calculated. In the econometric analysis, the Probit and Possion models are used to conduct benchmark regressions controlling for time and industry fixed effects. In order to clarify the path of action, the mediating effect models of human and material aspects are constructed at the micro level, and the moderating effect analysis of regional economy is conducted at the macro level. Afterwards, heterogeneity analysis by firm type and patent type further enriches the study. The final robustness test shows the reliability of the research in this paper.
