中文摘要：

中西部落后省份云贵两省产业结构呈现“三二一”的高级状态,两省的城乡居民收入 比也很高.基于长江经济带1 1个省市 1990-2015年产业结构高级化、合理化以及城乡居民 收入的相关数据,建立计量模型.研究结果表明：长江经济带产业结构高级化-定程度上扩大 了城乡收入差距,而产业结构合理化有利于城乡收入差距的缩小.产业结构向更高层次迈进 并非我国所有地区的普适任务.对于中西部省市来说,产业结构的合理化更有助于缩小城乡 收入差距,近期的主要任务应是促进产业结构合理化,减小产业结构与就业结构的偏离度.

英文摘要：

The industrial structure of Yunnan and Guizhou, backward in the central and western regions showed a high level state of “321 ”, and the income ratio of urban and rural residents in the two provinces was also high. An econometric model is built in this paper based on the data of the industrial structure optimization and rational-ization and the income of urban and rural residents in 11 provinces and cities of the Yangtze River Economic Zone from 1990 to 2015. The results show that the industrial structure optimization of the Yangtze River economic Zone widens the urban - rural income gap to a certain extent, and the rationalization of industrial structure is beneficial to narrowing urban - rural income gap. Moving towards a higher level of industrial structure is not a universal task for all regions of our country. For the central and western provinces and cities, the rationalization of industrial structure will help to narrow the income gap between urban and rural areas, and recently the main task should be to promote the rationalization of industrial structure and reduce the deviation of industrial structure and employment structure.
