【摘要】:農(nóng)業(yè)區(qū)域經(jīng)濟(jì)差異是普遍存在的,影響著一個(gè)地區(qū)和國(guó)家的經(jīng)濟(jì)社會(huì)進(jìn)步與穩(wěn)定。本文分別以云南省16個(gè)市州和129個(gè)縣為研究單元,從多尺度視角,建立主要指標(biāo)和綜合指標(biāo)兩組指標(biāo)集合,采用變異系數(shù)、基尼系數(shù)并結(jié)合數(shù)據(jù)比較和計(jì)算結(jié)果對(duì)比,測(cè)度1995-2014年的時(shí)間動(dòng)態(tài)變化;并選取4個(gè)時(shí)間截面作空間剖析;研究中使用ArcGIS、SPASS、GeoDa等多種現(xiàn)代技術(shù)和軟件相結(jié)合對(duì)統(tǒng)計(jì)數(shù)據(jù)進(jìn)行常規(guī)統(tǒng)計(jì)分析和空間統(tǒng)計(jì)分析,從而揭示了云南省市域和縣域農(nóng)業(yè)區(qū)域經(jīng)濟(jì)的時(shí)空演變特征。通過(guò)分析得出云南省農(nóng)業(yè)區(qū)域經(jīng)濟(jì)總體發(fā)展緩慢,局部發(fā)展較快,并呈現(xiàn)出顯著的東部發(fā)展水平較高,西北部發(fā)展水平很低的空間格局。從東往西大致呈橫“T字型”的特征,該特征在縣域?qū)用娓@著,近年來(lái)該“T字型”農(nóng)業(yè)區(qū)域經(jīng)濟(jì)帶有南北擴(kuò)散趨勢(shì),特別是往南擴(kuò)散更明顯。從時(shí)間序列得出,農(nóng)業(yè)總產(chǎn)值、農(nóng)村居民人均純收入均存在顯著的區(qū)域異,其中縣域?qū)硬町惛。變異系?shù)看兩個(gè)層面農(nóng)業(yè)總產(chǎn)值表現(xiàn)的區(qū)域差異更大,農(nóng)業(yè)總產(chǎn)值發(fā)展水平差異“先小后大”,反之,農(nóng)民人均純收入的區(qū)域差異是“先大后小”,并整體逐步縮小的趨勢(shì)發(fā)展;嵯禂(shù)也反映出與變異系數(shù)一致的變化特征;不同的是基尼系數(shù)反映出的云南農(nóng)業(yè)區(qū)域經(jīng)濟(jì)差異的時(shí)間變化市州層面比縣區(qū)層面變化更顯著。另外,對(duì)市州基尼系數(shù)進(jìn)行分解所得的差異貢獻(xiàn)結(jié)果可知,2008年前,農(nóng)、牧差異的貢獻(xiàn)率是其中較大的,而在2008后差異貢獻(xiàn)率最大的為副業(yè);此外,農(nóng)、林、牧、漁對(duì)差異的貢獻(xiàn)率總趨勢(shì)在減小。從空間分析看,市域?qū)又饕?個(gè)影響農(nóng)業(yè)市域經(jīng)濟(jì)的因子,并將綜合因子得分聚為4類(lèi);而縣域?qū)用嬷饕獮?個(gè)影響農(nóng)業(yè)縣域經(jīng)濟(jì)的因子,綜合因子得分聚為8類(lèi);以綜合因子得分作為反映云南省農(nóng)業(yè)區(qū)域經(jīng)濟(jì)的總體水平;得到的結(jié)果為:云南大面積處于欠發(fā)達(dá)以下水平,從東往西,即橫穿東、中、西中心軸線(xiàn)附近的縣區(qū)農(nóng)業(yè)區(qū)域經(jīng)濟(jì)水平發(fā)展較好,但中部城市化水平較高的縣區(qū)其農(nóng)業(yè)區(qū)域經(jīng)濟(jì)水平低于其周?chē)h區(qū)。因此,農(nóng)業(yè)區(qū)域經(jīng)濟(jì)水平受自然地理環(huán)境分異作用和人文地理環(huán)境影響,呈現(xiàn)出顯著的地域分異格局。從空間自相關(guān)分析結(jié)果可知,云南省農(nóng)業(yè)區(qū)域經(jīng)濟(jì)發(fā)展水平存在顯著的空間相關(guān)性,農(nóng)業(yè)區(qū)域經(jīng)濟(jì)水平高的區(qū)域在空間上相鄰,并集聚在一片區(qū)域,反之農(nóng)業(yè)區(qū)域經(jīng)濟(jì)水平較低的區(qū)域也空間相鄰并集聚在一起,但局域顯著性水平上農(nóng)業(yè)區(qū)域經(jīng)濟(jì)發(fā)展的區(qū)域帶動(dòng)作用不強(qiáng),農(nóng)業(yè)區(qū)域經(jīng)濟(jì)水平高的地區(qū)和差的地區(qū)多年來(lái)穩(wěn)定不變,兩極分化持續(xù)擴(kuò)大。
[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.
