摘要
文章建立了数字贸易发展指标体系,并创新地在增加值分解模型基础上利用2007~2014年WIOD数据库测算各国贸易利益水平,同时构建包含数字要素中间产品联合生产的理论模型,以考察数字贸易发展对一国贸易利益的提升作用。研究表明,数字贸易发展能够显著提高一国贸易利益水平,通过增强利益关联抑制价值链分工区域化、本土化趋势。分样本回归结果表明,数字贸易发展对低贸易成本国家及中、低技术行业贸易利益的促进作用更为明显。机制检验结果表明,数字贸易发展通过分工深化、产业升级和创新激励效应提高贸易利益水平。上述研究对于把握数字发展机遇,实现双循环畅通发展具有重要意义。
This paper establishes an indicator system for digital trade development,innovatively uses WIOD database from 2007 to 2014 to calculate the level of trade gains of various countries based on the value-added decomposition model,and constructs a theoretical model that includes the joint production of intermediate products containing digital factors to investigate the promotion effect of digital trade development on a country's trade gains.The research shows that digital trade development can significantly improve a country's level of trade gains and suppress the trend of regionalization and localization of division of labor in value chain by enhancing the connection of trade gains.The subsample regression results indicate that digital trade development has more significant promotion effect on trade gains of low-trade-cost countries as well as medium-tech and low-tech industries.The mechanism test results reveal that digital trade development improves the level of trade gains through the effect of deepening division of labor,the effect of industrial upgrading and the effect of innovation incentive.The above research is of great significance for seizing the opportunity of digital development and achieving the smooth development of dual circulation.
