摘要 在当前实施双循环发展战略的背景下,建设全国统一大市场是促进国内大循环的必然要求。理论上,数字经济的蓬勃发展为打破中国地区间市场分割状态提供了可能。从地区经济联系和行政垄断的双重视角,采用多元化计量方法,基于2006—2018年省级面板数据实证检验了数字经济发展影响市场分割的效应与作用机制。研究发现:第一,数字经济发展有助于降低市场分割,这一结论在处理内生性问题以及采用动态面板GMM估计等稳健性检验后依然成立,数字经济发展降低市场分割的影响存在长期效应,且呈现边际效应递增的特征;第二,分区域来看,数字经济降低市场分割的效应在中西部地区明显强于东部地区,在南方地区略强于北方地区;第三,机制检验证实数字经济能够通过强化地区经济联系和弱化行政垄断进而降低市场分割。研究结论不仅有助于从理论上廓清数字经济与市场分割的关系,也从实践上为破除地区市场分割、推动区域市场整合提供了思路。

Abstract： Under the background of the current implementation of the dual-cycle development strategy, the construction of a unified national market is an inevitable requirement to promote the domestic cycle. In theory, the vigorous development of the digital economy makes it possible to break the market segmentation between regions in China. From the dual perspective of regional economic relations and administrative monopoly, using diversified measurement methods, this paper empirically tests the effect and mechanism of digital economy development on market segmentation based on provincial panel data from 2006 to 2018. There are following findings. First, the development of digital economy helps to reduce market segmentation, which is still holds after dealing with endogenous problems and using dynamic panel GMM estimation. The impact of digital economic development on reducing the market segmentation has a long-term effect, and shows the characteristics of increasing marginal effect. Second, from a regional perspective, the effect of the digital economy on reducing market segmentation is significantly stronger in the central and western regions than that in the eastern regions, and slightly stronger in the southern regions than that in the northern regions. Third, the mechanism test confirms that the digital economy can reduce market segmentation by strengthening regional economic ties and weakening administrative monopoly. The conclusions not only help to clarify the relationship between digital economy and market segmentation in theory, but also provide ideas for breaking regional market segmentation and promoting regional market integration in practice.
Keywords： :Digital Economy   Market Segmentation   Long-term Effects   Regional Economic Linkages   Administrative Monopoly
