Does Imported Product Variety Improve Enterprises’ Energy Efficiency? ——Based On The Total Factor Method

Abstract

Based on the total factor method, this paper explores the relationship between imported product variety and enterprises’ energy efficiency by using Statistics from China. The study finds that the types of imported products considerably improve the energy efficiency of enterprises. After accounting for endogeneity, changing test methods, and using different measures, the core conclusion remains valid. Mechanism tests indicate that the technology spillover effect and competition effect are two important channels through which imported product variety enhances enterprises’ energy efficiency. Heterogeneity test results show that the types of imported products have a greater impact on improving energy efficiency.
