Research On The Loss Of Monopoly Efficiency Of Digital Economy Platform

The digital economy is a valuable opportunity for China ’s economy to achieve lane change and overtaking in the fourth industrial revolution,and has very important strategic significance for achieving high-quality development and the great rejuvenation of the Chinese nation.The rapid development of the digital economy has spawned the platform economy as a new form of industrial organization.However,with the rapid development of the Internet platform,its market structure has gradually evolved into the competitive effect of ’ winner-take-all,the stronger the stronger ’,and the platform monopoly chaos occurs frequently,which seriously affects the healthy and sustainable development of the digital economy.How to deal with the monopoly of digital platforms and how to effectively suppress the efficiency loss caused by the monopoly of digital platforms is a new problem that needs to be solved urgently and contains new opportunities for China and even the global economy in the new era.Only by fully understanding the causes of platform monopoly and the composition of efficiency loss can we find the correct anti-monopoly regulation of digital economic platforms and promote the healthy development of the digital economic platform market.This thesis uses a combination of theoretical and empirical system test methods to examine the efficiency loss caused by platform monopoly.In theory,first of all,it analyzes the current situation of market monopoly of digital economy platform,and refers to the SCP industry analysis framework,mainly from the market structure of digital economy platform,the monopoly behavior characteristics of digital economy platform,and the connotation of monopoly efficiency loss of digital economy platform.Then,from the perspective of Marxist political economy,the endogenous monopoly process and efficiency loss mechanism of platform production are deeply analyzed,and the general rules of platform monopoly and efficiency loss are revealed.In the empirical analysis part,36 Internet platform listed companies from 2015 to2021 were selected as research samples.Based on the two-stage DEA-Tobit model,the efficiency status of the Internet platform industry and the efficiency loss mechanism caused by platform monopoly were empirically tested.The empirical results show that :(1)From 2015 to 2021,the overall resource utilization of the Internet platform industry is low,and there is a certain degree of resource waste.Both pure technical efficiency and scale efficiency do not reach the effective standard of efficiency value.The average values of the three efficiencies are 0.874,0.925 and0.944,respectively.(2)The development of Internet technology such as algorithms contributes the most to total factor productivity.The comprehensive technical efficiency loss of the three types of Internet platforms comes from pure technical efficiency,indicating that the resource management level of the three types of platform industries is low.(3)The industry concentration of digital economy platform is negatively correlated with industry efficiency,and the vertical integration of platform enterprises has a slight promoting effect on industry efficiency.A better macroeconomic environment will promote the overall efficiency of the Internet industry;the older the enterprise,the higher the production efficiency of the company;corporate social responsibility has an inhibitory effect on industry efficiency.The above conclusions reveal the negative impact of digital economy platform monopoly on industry efficiency.In order to promote the healthy development of platform economy and regulate platform monopoly scientifically and reasonably,this thesis puts forward the following policy recommendations :(1)Actively promote anti-monopoly legislation in the field of digital economy platform,improve the burden of proof system in the platform market,the subsidy policy of Internet platform enterprises,and reduce the entry barriers of industry economy.(2)Strengthen the protection of consumer privacy data,clarify the division standards of data ownership and use rights in the platform field,and establish and improve the tax system in the data market.(3)Establish incentive mechanism to encourage platform enterprises to carry out technological development,encourage enterprises to set up research institutes,establish industry-university-research chain,guide large-scale Internet platforms with redundant investment to invest in platform enterprises with insufficient investment scale with excess capital,and optimize resource allocation.(4)Establish a digital economy market department to achieve special management,focus on strengthening legal research in the field of digital economy in China,carry out interdisciplinary and digital law disciplines such as legal economy in colleges and universities,and cultivate professional and technical talents.
