中国西部城乡经济一体化水平及其全国比较——基于省级面板数据的实证检验

Measurement of Urban-rural Economic Integration Level in Western China and National Comparison—Empirical Examination Based on Provincial Panel Data

本文在理清城乡经济一体化内涵的基础上,构建包含4个维度共27个基础指标的水平评价指标体系,使用两步主成分分析对中国西部省份的城乡经济一体化指数进行测度。结果表明,21世纪以来西部整体城乡经济一体化指数呈稳步上升态势,四个维度指数的增长趋势存在显著差异;西部省份城乡经济一体化指数不断攀升,省际差异明显且呈现"橄榄型"分布;在全国比较中,西部城乡经济一体化水平低于东部、中部和东北,且低于同期全国平均水平。从变动趋势看,西部城乡经济一体化水平的提升速度略高于东北,与中部和东北的差距不断缩小,与东部的差距不断扩大并形成"两级分化"的态势。根据上述结论,从分类制定政策、城乡产业结构、城乡经济发展等角度提出政策建议。

Based on the study of urban-rural economic integration connotation, this paper constructs evaluation index system of urban-rural economic integration which includes 27 basic indicators of 4 dimensions and uses the method of two-step principal component analysis to measure the urban-rural economic integration level of 11 provinces in the western region of China. The results show that since 21th century, urban-rural economic integration index of western region of China showed a steady upward trend; that there is obvious difference in four dimensions index growth trend, that urban-rural economic integration index of 11 provinces in western China continues growth, inter-provincial difference is obvious and presented an ＂olive-shaped＂ distribution. In national comparison, the urban-rural integration level in western China is lower than that of the east, the middle and the northeast part of China and is lower than the average level of China. From the perspective of changing trend, the promotion speed of the urban-rural economic integration level in western China is slightly higher than that of northeast part of China, is narrowing with the level of the middle and northeast part of China, but continues to enlarge the gap with the east part of China and forms polarization trend. Policy and suggestions are advanced from the perspective of classification policy, urban-rural industrial strueture, urBan-rural economic development and so on based on above conclusions.
