竞争与反竞争:论互联网与市场势力的中国实践

Competition and Anti-competition:on the Practice of Internet and Market Power in China

将互联网纳入企业市场势力分析框架,从提高信息对称性、增强技术可复制性、降低进入壁垒和成本等多维度构建理论分析框架,探究互联网通过竞争效应对企业市场势力的作用路径,并利用2015—2017年中国上市公司的面板数据进行实证检验.研究发现:互联网对企业市场势力具有显著的抑制作用,并因企业异质性而存在较大的差异,即互联网对非国有企业市场势力的抑制作用明显大于国有企业,互联网对东部地区企业市场势力的抑制作用明显强于西部地区.由于存在显著网络效应,互联网对企业市场势力的抑制作用呈现显著的非线性影响,即抑制作用先逐渐增强达到特定门槛值后逐渐减弱.最后结合本文结论和中国实际提出促进互联网与企业融合发展的政策建议.

This paper brings the Internet into the analysis framework of enterprise market power,constructs a theoretical analysis framework from the aspects of improving information symmetry,enhancing technology replicability,reducing entry barriers and costs,explores the path of the Internet*s effect on enterprise market power through competitive effect,and makes an empirical test using the panel data of China*s listed companies from 2015 to 2017.The results show that:the Internet has a significant inhibitory effect on the market power of enterprises,and there are great differences due to the heterogeneity of enterprises.That is to say,the restraining effect of Internet on the market power of non-state-owned enterprises is significantly greater than that of state-owned enterprises,and the restraining effect of Internet on the market power of enterprises in the eastern region is significantly stronger than that in the western region.Due to the existence of significant network effect,the inhibition of the Internet on the market power of enterprises presents a significant nonlinear effect,that is,the inhibition first increases and then decreases after reaching a specific threshold.Finally,combined with the conclusion of this paper and the actual situation in China,the paper gives some policy suggestions to promote the development of Internet and enterprise integration.
