Selecting data samples from 30 provinces,a comprehensive evaluation system for e-commerce development was constructed from four perspectives:e-commerce development capacity,e-commerce service level,internet infrastructure level,and policy development level.Based on a two-way effect panel model,the impact of e-commerce development on household consumption level was empirically verified,as well as the moderating effect of commodity transaction costs between the two.The research results indicate that the development of e-commerce has a positive promoting effect on the consumption level of residents,and the transaction cost of goods can negatively regulate the relationship between the two.Therefore,it is necessary to increase policy support for the e-commerce field,improve the quality of e-commerce products,strengthen brand building,improve network,logistics and other infrastructure construction to promote the healthy and orderly development of e-commerce and promote the improvement of consumer level among residents.
