摘要
本文基于面板向量自回归模型（PVAR），通过构建产业内部结构偏离指数，采用我国2005－2014年31个省市自治区的面板数据进行实证分析，结果表明：产业内部结构偏离最优水平在长期内会扩大城乡收入差距，在短期内反而可以起到缩小收入差距的作用，最优的产业结构并不一定能够带来较低的收入差距水平；城乡收入差距主要受其自身波动的影响，即在没有外界干扰的情况下，收入差距的变化趋势具有一定惯性。
To explain the income disparity between urban and rural areas of China, we construct the industri- al internal structure deviation index via entropy method and based on the Panel Data Vector Autoregression （PVAR） model, collect provincial panel data of China from 2005 to 2014 to carry out empirical analysis. The result shows that the industrial internal structure deviating from the optimal level will widen the income disparity in the long run whereas narrow the income disparity to some degree in the short run, which means that the optimal industrial structure does not always correspond to lower level of income disparity. Besides, the income disparity is mainly affected by its own fluctuations. Namely, in the absence of external interference, the trend of the income disparity has certain inertia.
