国家级大数据综合试验区设立对区域数字经济发展的效应评估

Effect Assessment of National Big Data Comprehensive Pilot Zones on Regional Digital Economy Development

摘要:

为加快推动区域数字经济发展从而带动区域经济整体发展，基于我国30个省份2012－2019年的面板数据构建数字经济发展水平评价指标体系，得到各省份数字经济发展水平得分，构建渐进双重差分模型实证检验国家级大数据综合试验区对区域数字经济发展的政策效应，并分析区域异质性和试验区类型差异性的影响效应，从而探讨创设国家级大数据综合试验区对区域数字经济发展的影响路径。研究表明：创设国家级大数据综合试验区显著促进区域数字经济发展，并且所产生的政策效应与区域发达程度有关，其中对东部数字经济发展水平提升作用更加显著，但同时也为经济欠发达地区实现数字经济的后发赶超提供契机；影响效应差异在短期内并不显著，但从长期来看跨区域类型试验区有更深远的政策效应；对区域数字经济发展的影响路径表现为调整区域产业结构、提升政府管理能力和规范市场环境等方面。最后根据研究结论，提出贯彻大数据战略、构建发展评价体系和创新适合数字经济发展的商业模式等政策建议。

Abstract:

In order to accelerate the development of regional digital economy so as to drive the overall development of regional economy, this paper constructs an evaluation index system of digital economy development level based on the panel data of 30 provinces in China from 2012 to 2019, obtains the digital economy development level score of each province, and constructs an asymptotic double difference model to empirically test the effect of national big data comprehensive pilot zones on the development of regional digital economy, further analyses the effects of regional heterogeneity and differences in the types of pilot zones, so as to explore the influence paths of creating national big data comprehensive pilot zones on the development of regional digital economy. The results show that the policy effects of creating national big data comprehensive pilot zones significantly contribute to the development of regional digital economy, and the effects are related to the degree of regional development, with a more significant effect on the east of China, but also providing opportunities for less developed regions of China to catch up in digital economy; in the short term, the difference in impact effects is not significant, but in the long term, the cross-regional pilot zones have more far-reaching policy effects; the impact paths on the regional digital economy development are manifested in the adjustment of regional industrial structure, the improvement of government management capacity and the regulation of market environment. Finally, based on the above findings, the paper proposes some policy recommendations such as implementing the big data strategy, constructing a development evaluation system and innovating a business model suitable for the development of the digital economy.
