Digital Trade,Chain Modernization and New Quality Productivity Forces
Digital trade and new quality productivity forces have become the key to promote high-quality economic growth.Based on the panel data of 31 provinces(municipalities and autonomous regions)in China from2011 to2022,the evaluation system of new quality productivity forces inde-xes is constructed with three dimensions of scientific and technological productivity,green productivity,and digital productivity,and then the entropy weight-TOPIS method is applied to measure the level of regional new quality productivity forces.Then,the entropy weight-TOPIS method is used to measure the level of regional new quality productivity forces.The influence of digital trade,industrial chain modernization and new quality produc-tivity forces and their mechanisms are analyzed by two-way fixed effect model and mediation effect model.The study shows that:digital trade can not only promote the level of new quality productivity forces,but also shows the characteristics of regional heterogeneity;industry chain moderniza-tion plays an intermediary role in the process of the impact of digital trade on new quality productivity forces.Digital trade has a positive and signifi-cant effect on new quality productivity forces by driving industrial chain modernization.
