摘　　要：市场准入规制是中国政府规制的主要形式之一,因而放松市场准入规制是充分发挥市场在资源配置中的决定性作用的重要手段,对于激发民营企业活力和实现经济高质量发展有重要意义。本文选取2008—2017年全球13个国家的宽带业务面板数据,采用基于随机推断的双重差分模型,实证检验了放松市场准入规制对市场价格和产出的影响,以此来验证中国自然垄断行业放松市场准入规制改革政策的有效性。研究结果表明:放松市场准入规制能够有效降低宽带业务的市场价格,并显著提高其产出。经过一系列稳健性检验后,上述结果依然成立。基于此,笔者提出以下政策建议:将放松市场准入规制改革逐步延伸到其他具备条件的自然垄断行业,促进基本公共服务实现均等化;支持民营企业公平参与市场竞争,优化民营经济发展环境;以改革的方式促消费,推动扩大内需战略的实施。本文引入随机推断法有助于双重差分模型在政策绩效评估中的进一步科学应用。Summary:Market access regulations is one of the main forms of government regulation in China,so relaxing market access regulations is an important means to give full play to the decisive role of the market in resource allocation,and is of great significance to stimulate the vitality of private enterprises and achieve high‑quality economic development.However,compared with competitive industries,natural monopoly industries have been the most difficult field of reform,and there are still many concerns about relaxing market access regulations in natural monopoly industries.So it is of great academic value and urgent practical significance to research on relaxing market access regulations in natural monopoly industries.This paper selects the broadband business panel data of 13 countries from 2008 to 2017,and adopts the RI‑DID model to empirically test the impact of relaxing market access regulations on market prices and output,so as to verify the effectiveness of relaxing market access regulations in Chinas natural monopoly industries.The results show that relaxing market access regulations can significantly reduce the market price of broadband services and significantly increase the output.After a series of robustness tests,the results are still valid.Compared with existing research,main marginal contributions of this paper are as follows.First,this paper improves the data selection method to avoid misjudgment of natural monopoly attributes caused by excessive monopoly profits,and thus tests the natural monopoly attributes of Chinas broadband services.Second,the conclusions of this paper help to reduce the academic and industrial concerns about relaxing market access regulations in natural monopoly industries to a certain extent,and provide empirical evidence for the further reform of natural monopoly industries.Third,this paper applies the RI‑DID model to the empirical study of natural monopoly industries to overcome the defect of insufficient research samples of natural monopoly industries,which provides a r
