我国各省市金融垄断程度判断——基于金融勒纳指数的分析

The Judgment of Monopoly Degree on Provincial-level Financial Markets in China:An Analysis Based on Financial Lerner Index

文章以勒纳指数作为衡量指标,对中国各省市金融市场垄断程度的差异进行实证研究,认为虽然经过多年的市场经济建设,但中国金融业整体上仍然表现出明显的垄断特征。各省市的金融市场垄断程度具有明显的不平衡性,且与各自经济发展水平呈负相关关系,即在经济发展水平较高的省市金融垄断程度较低,反之则金融垄断程度高。这表明金融作为现代经济的核心,中国的金融市场化改革能够显著推动经济的发展。文章建议可以从加速市场开放、打破地区封锁和资源配置的效率导向等方面加以完善,以降低因金融市场垄断而造成的社会福利损失。

Taking Lerner index as an indicator, the paper empirically studies the monopoly degree of provincial-level financial markets in China. The results show that although market economy has been carried out for many years, the financial industry in China is still obviously featured by monopoly. Furthermore,the monopoly degree on provincial-level financial markets varies wildly and is negatively correlated with local economic development. It suggests that finance is the focus of modern economics and financial market reform in China can significantly promote economic development. The paper puts forward to some suggestion in order to reduce social welfare loss caused by monopolistic competition on financial markets.
