A Study on the Relationship between Corruption and Economic Growth——Based on Provincial Panel Data Analysis

腐败已成为当今中国经济社会转型的焦点问题。本文从腐败的内涵及外延着手，首先梳理以往关于腐败与经济增长关系的理论，并重点研究、论述了中外相关反腐倡廉思想。在此基础上，本文通过构建腐败的博弈理论模型发现，在假设不考虑相关成本的情况下，腐败行为只是腐败双方的零和博弈，并不产生价值，反而会扭曲社会资源配置，导致市场不能达到最优状态；而在存在相关成本的情况下，腐败除了扭曲资源配置之外，还存在对社会的负面成本。进一步地，本文从理论模型得出结论：腐败抑制经济增长，扭曲资源配置。为检验上述假说与研究腐败影响经济增长的途径，本文采用《中国检察年鉴》公布的腐败立案数来度量省级腐败，并运用DEA-Malmquist...Corruption has become the focus of China's economic and social transformation. This paper begins with the connotation and extension of corruption, and combs the previous theory of the relationship between corruption and economic growth, and discussed the relevant Chinese and foreign anti-corruption ideas. Then, this paper constructs the game theory model of corruption, it is found that corruption ...学位：经济学硕士院系专业：经济学院_经济思想史学号：1532014115213
