云南省城乡经济差异演变的时空分析

选取云南省城镇居民家庭人均可支配收入和农村家庭人均纯收入作为分析的变量指标，采集《云南年鉴》和《云南统计年鉴》中1978～2007年的相关数据，采用RHL值和泰尔指数，对云南省城乡经济差异的发生、发展和变化进行定量研究，并通过经济增长对城乡差异收敛与发散的空间分析及城乡经济差异演变趋势进行回归分析。结果表明，1978～2007年，城市经济发展以向下收敛为主，农村经济发展以向下发散为主，导致城乡发展分离趋异，总体表现云南城乡差距扩大，农村地区的发展远远滞后于城镇的发展；城乡差异发展趋势显示库兹尼次曲线的倒“U”形特征。为促进城乡经济的协调发展，提出以下建议：采取非均衡发展的战略，加速总体经济发展；培育和发展中小城市，促进城乡经济一体化发展；适当扶持贫困农村地区，充分发挥比较优势。

Spatial Analysis of the Evolvement of Urban and Rural Economic Disparity in Yunnan Province

The per capita disposable income of urban households and the per capita net income of rural households in Yunnan Province are selected as the variable indices.Data are from the Yunnan Statistical Yearbook and the Yunnan Statistical Yearbook7-8].Theil index and RHL value are used to carry out quantitative research on the occurrence,development and change of urban and rural economic disparity in Yunnan Province,China.Regression analysis on the evolvement trend of urban and rural economic disparity and spatial analysis on the convergence and divergence of urban and rural disparity caused by economic growth in Yunnan Province are carried out.Result shows that cities in Yunnan Province show a downward convergence; while rural areas show a downward divergence in the years 1978-2007,causing the economic disparity between urban and rural areas.Therefore,urban and rural disparity increases in Yunnan Province and the development of rural areas lags far behind the development of urban areas.Urban and rural economic disparity in Yunnan Province shows an inverted "U" shape of Kuznets Curve.In order to promote the coordinated development of urban and rural economy,suggestions are put forward,such as adopting the unbalanced development strategy,accelerating the overall economic development,promoting the development of small and medium-sized cities,enhancing the integration of urban and rural economics,appropriately supporting rural areas under poverty,and fully exerting the comparative advantage.
