摘要：本文提出政务服务市场假说，为政府自身的系列改革提供了一个逻辑自洽的解释。在理论上，本文证明，当政务服务市场和产品市场同时均衡时，均衡企业办事成本是政府审批事项数量和办事方式的增函数，精简办事事项和优化办事方式有利于降低企业均衡办事成本。在实证上，本文基于对全国 28818家企业实地访谈，度量2018—2022年企业办事成本，发现与理论预期一致，政务服务市场建设降低了企业办事成本。

Abstract: This paper proposes a novel administrative approval market hypothesis to offer a coherent explanation for government administrative approval reforms. Theoretically, this paper shows that when simultaneous equilibria are achieved in administrative approval market and the production market, the institutional cost of firms is a increasing function ofthe number of administrative approval items,and the approach of administrative services. Empirically, utilizing our field survey of 28,818 firms across China from 2018 to 2022, we find consistent results with ourtheoretical prediction, that the advancements of the administrative approval market reduce the bureaucratic costs of firms.
