Digital Economy Enables High-Quality Economic Development: Theoretical Mechanisms and Empirical Evidence

Digital economy has become the primary motivation for high-quality economic development. Upon comprehensively analyzing the connotation of digital economy, this paper constructs an evaluation system from development environment, digital industrialization, industrial digitalization, and digital governance to measure China’s digital economy index from 2016 to 2018 using the entropy-based TOPSIS method. Also, based on the improved Feder dual sector model, this paper discusses the theoretical mechanism of digital economy promoting high-quality economic development directly and through improving economic efficiency and economic structure, and carries out an empirical test. According to findings, on the one hand, China is scaling up digital economy and accelerating digital transformation; on the other hand, the greater the likelihood that high-quality economic development is constrained by low economic efficiency and unreasonable economic structure, the greater the role of digital economy in promoting high-quality economic development. Therefore, this paper puts forward recommendations for China’s high-quality economic development, such as advancing new infrastructure construction, developing digital economy, improving economic efficiency and economic structure, and transforming the government governance model.     

黄河流域横向生态补偿标准的测度研究

黄河流域生态补偿是重要的制度创新，而补偿标准测算是黄河流域生态补偿机制构建的关键环节。首先客观评价黄河流域各省界断面的水质状况，判断各省区应该进行保护补偿或损害赔偿。然后，构建基于水质恢复成本的差异化补偿标准测算模型，对黄河流域各省区的横向保护补偿金额和横向损害赔偿金额分别进行测算。结果表明黄河干流2019年整体水质状况较好，但仍存在横向生态补偿的必要性；通过综合测算，青海、甘肃、山东应该得到补偿；宁夏、内蒙古、山西、陕西和河南应该进行赔偿。研究思路和对策建议对黄河流域的生态补偿机制运行和完善有一定的借鉴意义。
