摘　　要：垄断管制及相关产业组织政策制定的一个关键问题是对企业市场势力的科学准确的测度。而处于垄断地位的企业,通过提高工资福利待遇拉大生产经营成本,则可能掩盖其真实的市场势力。采用企业单位工资产出率与行业单位工资产出率的比值对勒纳指数进行修正,解决已有的市场势力测度方法不能测度企业通过提高工资待遇的方式掩盖其市场势力的问题。运用修正的勒纳指数对我国大型工业企业市场势力进行实际测算,结果表明:我国不同行业大型工业企业都使用了显性市场势力和隐性市场势力;其中市场化程度高的行业隐性市场势力大于市场化程度低的行业,而市场化程度低的行业显性市场势力则大于市场化程度高的行业。市场势力测度的更深层意义在于分析政府与垄断企业之间的博弈以调整当前政策制定与管制方法,解决市场供给侧改革过程中存在的问题,因此应依据测算结果,继续深化市场体制改革,完善垄断监管政策措施。Using ratio of enterprises unit wage productivity and industrial unit wage productivity modifies the Lemer index,this study solved methodological issue that the existing methods cannot measure companies’ market power accurately if the companies raise salaries to conceal it. Based on the modified Lerner index, this paper estimates China large industrial enterprises market power. The results show that large enterprises across different industries in China all have both dominant market power and implicit market power. Furthermore, the higher degree of marketization of the industry the higher level of implicit market power while the lower degree of marketization of the industry the higher level of dominant market power. The policy implication of market power is that government should continue deepening market economic reform and improving monopoly regulato-ry policies.
