摘要
文章基于数字经济内涵的界定选取代表性指标,构建"一带一路"沿线国家数字经济发展指标评价体系,采用主成分分析法定量测度"一带一路"沿线43个国家的数字经济发展水平,实证检验东道国数字经济发展对中国对外直接投资区位偏好和规模变化的影响,研究发现:"一带一路"沿线国家间数字经济发展水平差距明显,但却显著促进中国对其直接投资规模的提升并成为区位选择的决定因素。中介效应模型检验结果显示东道国数字经济发展存在通过"贸易成本效应"和"制度质量效应"的改变吸引中国对其投资的影响机制。
Based on the definition of the connotation of digital economy,this paper selects the representative indicators and constructs the evaluation system of digital economy development indicators of the countries along the Belt and Road(B&R).The paper also quantitatively measures the development level of digital economy of 43 countries along B&R by using principal component analysis method,and empirically examines the influence of the host country’s digital economy development on the location preference and scale changes of China’s outward foreign direct investment(OFDI).The research shows that the gap in the digital economy development level among the countries along B&R is obvious,but it significantly promotes the scale of China’s direct investment and becomes a determinant of location choice.The result of mediating effect model reveals that the development of the host country’s digital economy has the influence mechanism of attracting China’s investment through the change of trade cost effect and institutional quality effect.
