摘要
本文以7个代表性转型国家1986-2009年跨国面板数据为样本,利用面板数据模型分析了收入差距对经济增长影响轨迹是否呈倒U型曲线。研究结果表明,转型国家收入差距与经济增长之间存在倒U型曲线关系。即使在样本中除去收入差距较严重的中国数据,收入差距对经济增长影响的倒U型曲线的证据仍然存在。近似计算,基尼系数为0.42是收入差距对经济增长影响由正变负的拐点。本文还发现,经济自由度这一制度因素对中国经济增长有较大影响。中国政府应积极探索有利于缩小收入差距,促进经济增长的经济发展方式及制度环境,包括加大公共服务供给,健全社会保障体系,进一步推进国有企业改革,推进政府体制改革,推动市场化进程,纠正要素价格扭曲行为,打破垄断,深化税制改革,完善转移支付制度等。
This paper tests if the effect of inequality on growth presents as an inverted U-shaped curve with the panel data of seven representative transition economies from 1986 to 2009. The results show that the effect of inequality on growth does present as an inverted U-shaped curve. By approximate calculation, the effect of inequality on growth varies from positive to negative when the Gini coefficient reaches 0.42. China＇s economic institutions have important impacts on economic growth. The Chinese government should actively explore innovative economic development mode and institutional environments, including further reform of state-owned enterprises and government system, break of the monopoly, and the improvement of social security system in order to form the ＂ win-win＂ situation of economic growth and income distribution.
