文章将沉没成本引入可竞争市场进入障碍模型,揭示了自然垄断行业中民间资本进入竞争与行政垄断损害社会福利和效率的机理,然后对我国工业垄断行业行政垄断危害进行实证研究。研究发现,2005-2013年我国工业7个行业行政垄断导致每年社会福利和管理费用损失占我国GDP的比重分别达1.29%-2.89%、0.22%-0.86%,并导致工业各行业就业人员收入差距扩大。基于研究结果,建议加快改革我国政府部门以行政手段渗入自然垄断领域的制度安排,降低潜在进入企业的沉没成本,积极引进民间资本竞争。
The paper introduces the sunk cost into the barrier model of competitive market entry, and reveals the mechanism of private capital entering the competition and administrative monopoly in natural monopoly industries that undermines social welfare and efficiency. Then, this paper conducts an empirical study on the harm of administrative monopoly in China’s industrial monopoly industries. The study found that from 2005 to 2013, the administrative monopoly of seven industries in our country led to the annual loss of social welfare and administrative expenses accounting for 1.29% -2.89% and 0.22% -0.86% of the national GDP, respectively, and led to the income gap among employed persons in various industries expand. Based on the research results, it is suggested to speed up the reform of the institutional arrangements for government departments in our country to infiltrate the natural monopoly field with administrative measures, reduce the sunk cost of potential entry enterprises and actively introduce non-governmental capital competition.
