Input Digitization and Upgrading of Export Product Quality Structure:Empirical Evidence from Chinese Multi-Product Exporters
This paper provides a theoretical analysis of the influence mechanism of input digitali-zation on the quality structure of export products.Furthermore,it conducts empirical testing based on the World Input Output Database,China Customs Import and Export Database,and China Industrial Enterprise Database.The mechanism test shows that input digitalization mainly optimizes the quality structure of export products through three channels:quality differentiation adjustment of internal products,marginal cost differentiation adjustment of internal products,and improvement of product conversion ability.The heterogeneity test shows that compared with me-dium,small and micro-sized enterprises,input digitalization has a larger effect on the optimiza-tion of export product quality structure of large-scale enterprises;and the effect of input digitali-zation on export product quality structure of enterprise groups in high competitive industries and non-resource-based cities is significantly higher than that of low competitive industries and re-source-based cities.
