摘　　要：中国渐进式市场化改革和地区收入差距扩大的现实背景,为深入探寻经济发展和收入差距背后的经济规律,提供了极具启发性的研究线索。通过引入专业化分工和交易成本,本文构建了超边际分析视角下地区收入差距的理论模型,揭示了经济系统中分工演进与制度环境影响下交易效率之间的逻辑关系,数值模拟进一步表明不同的交易效率演变路径是引致地区之间收入差距发展变化的重要原因。因此,强调交易制度的重要性,努力改善落后地区的市场化交易环境,是缩小中国地区收入差距的根本途径。The background of gradual market-oriented reform and regional income disparities of China provide some enlightening clues for exploring the economic laws of economic development gap. Through the introduction of specialization and transaction costs, we established a theoretical model of regional income disparity in the inframarginal perspective which reveals the logical relationship between the evolution of division of labor and transaction efficiency under influence of institutional environment, and numerical simulation illustrate that different evolution path of transaction efficiency is an important reason for the development and changes caused by the income gap between regions. Therefore, we think that further improving the market-oriented trading environment of the middle and western regions has a great significance for narrowing regional income disparity in China.
