云南省農(nóng)業(yè)區(qū)域經(jīng)濟(jì)差異研究
[Abstract]:Agricultural regional economic differences are common and affect the economic and social progress and stability of a region and a country. In this paper, 16 prefectures and 129 counties in Yunnan Province are taken as the research units. From the view of multi-scale, two sets of main indexes and comprehensive indexes are established. The coefficient of variation, the Gini coefficient, the data comparison and the comparison of the calculated results are adopted. Measure the time dynamics of 1995-2014; Four time sections are selected for spatial analysis. In this study, ArcGIS,SPASS,GeoDa and other modern techniques and software were used to analyze the statistical data, which revealed the temporal and spatial evolution characteristics of the agricultural regional economy in Yunnan Province. It is concluded that the agricultural regional economy in Yunnan Province is developing slowly and locally, and the spatial pattern of higher level of development in the eastern part and lower level in the northwest of Yunnan Province is presented. From east to west, there is a transverse "T" pattern, which is more obvious at the county level. In recent years, the "T-shaped" agricultural regional economy has a tendency to spread from north to south, especially to the south. From the time series, there are significant regional differences in the total agricultural output value and the per capita net income of rural residents, among which the difference in county level is even greater. The coefficient of variation shows a greater regional difference in the performance of the total agricultural output value at the two levels. The difference in the level of development of agricultural output value is "small first and then great", whereas the regional difference in the per capita net income of farmers is "the first big after the small". And the overall trend of gradual narrowing of the development. The Gini coefficient also reflects the change characteristics consistent with the variation coefficient, but the difference is that the temporal change of the economic difference in Yunnan agricultural regions reflected by the Gini coefficient is more significant at the city level than at the county level. In addition, the results of the analysis of the Gini coefficient showed that before 2008, the contribution rate of the difference between agriculture and animal husbandry was greater, but after 2008, the contribution rate of the difference was the sideline. In addition, the contribution rate of agriculture, forestry, animal husbandry and fishery to the difference is decreasing. From the spatial analysis, there are three factors that affect the agricultural economy in the city level, and the scores of the comprehensive factors are divided into four categories, while the county level is mainly two factors affecting the agricultural county economy, and the score of the comprehensive factors is 8 categories. Taking the comprehensive factor score as the reflection of the overall level of agricultural regional economy in Yunnan Province; The results are as follows: a large area of Yunnan is below the level of underdevelopment, and the agricultural regional economic level of the county area near the central axis of the east, middle and west is better developed from east to west, that is, across the east to the west. However, the agricultural regional economic level of the counties with higher urbanization level in the central region is lower than that of the surrounding counties. Therefore, the regional economic level of agriculture is affected by the differentiation of natural geographical environment and the human geographical environment, showing a significant pattern of regional differentiation. The results of spatial autocorrelation analysis show that there is a significant spatial correlation in the level of agricultural regional economic development in Yunnan Province. The regions with high economic level of agriculture are adjacent to each other in space and gather in a region. On the contrary, the regions with lower level of agricultural economy are adjacent to each other and gather together in space, but the regional driving effect of regional economic development is not strong at the level of local significance. Agricultural regions with high economic levels and poor areas have remained stable for many years, and polarization has continued to expand.
