Study On Agricultural Regional Economic Disparity In Yunnan Province

Agricultural regional economic difference is widespread, affecting a regional and national economic and social progress and stability. This paper respectively in 16 states and 129 counties of yunnan province as the research unit, from the perspectives of multi-scale and establish the main index and comprehensive index set two groups of indicators, using coefficient of variation, the gini coefficient and the results combined with data comparison and contrast, measure time dynamic change from1995 to 2014; Selection and four time section analysis space; Study using ArcGIS,SPASS, GeoDa and various combination of modern technology and software for statistical data for regular statistical analysis and spatial statistical analysis, so as to reveal the district and county of yunnan province agricultural spatial and temporal evolution of regional economy.Through the analysis of yunnan agricultural regional economy overall development is slow, local development faster, and present a significant eastern development level is higher, the northwest development level low spatial pattern.From east to west is roughly horizontal "T word" characteristics, the characteristics are more significant at the county level, in recent years, the "T word" agricultural regional economy with the diffusion trend, especially in the south of diffusion is more obvious.From the time series, agricultural output value, per capita net income of rural residents are significant regional variations, including county level difference is bigger. Agricultural output coefficient of variation of the two levels of regional difference is larger, difference of the agricultural output "after the first small big", on the other hand, the regional difference of per capita net income of farmers is a "small" big first, and gradually reduce the trend of development as a whole. Gini coefficient reflects the consistent with the variation coefficient of variation characteristics;Different is the gini coefficient reflects the difference of regional economy of yunnan agriculture changes time municipal level than the county level is more significant. In addition, the gini coefficient decomposition income of city state difference contribution result shows that 2008 years ago, the contribution rate of agriculture,animal husbandry differences is one of the larger, and after the 2008 biggest difference contribution to sideline; In addition, agriculture, forestry, animal husbandry and fishery to differences in reducing the contribution rate of total trend.Layer from the spatial analysis, xiamen city there are mainly three factors affecting agricultural regional economy, the comprehensive factor score and divided into 4 classes; County level mainly two factors affecting agricultural county economy,comprehensive factor score into 8 classes; With the comprehensive factor scorereflecting the overall level of agricultural regional economy in yunnan province;Results are as follows: yunnan under large area in the less developed level, from the east to the west, namely across the eastern, central and west near the center of a county agricultural regional economy level of development is good, but the urbanization level is higher in central county agricultural regional economic level is lower than the surrounding counties. Therefore, agricultural regional economic level differentiation by natural geographical environment and human geography environment, presents the obvious regional differentiation pattern. From spatial autocorrelation analysis result shows that agriculture in yunnan province plays a significant role in regional economic development level of spatial correlation, high level of agricultural regional economic area adjacent in the space, and gather in an area, instead of the low level of the regional economic area agriculture also space adjacent and gather together, but local significance level on agricultural area leading role of the regional economic development is not strong, poor agricultural regions with high levels of regional economy and regional stable over the years, polarization continues to expand.
