【摘要】：采用基尼系数、重心模型、ESDA方法和空间计量分析模型,探究了1988-2013年中国渔业地理集聚时空特征及影响因素。研究发现:1)中国渔业一直存在显著的地理集聚现象和空间自相关特征,渔业地理重心的变化范围主要分布在长江中下游沿线的皖、赣、鄂三省以及苏、皖两省的淮河以北和江淮之间;2)渔业空间关联格局中的热点区和次热点区在26年间数量减少近半,冷点区和次冷点区数量增多,但未发生变化的类型区居于主体,发生变化的类型区基本表现为梯次逐级减弱的演变特征,各类型区初始呈现出的集中连片分布态势和梯度推移性变化规律渐趋不明显;3)渔业具有正的省际空间溢出效应,沿海地区、产业外部性、人力资本、消费需求、城镇化率、技术水平、产业外向度、政府干预度都会影响中国渔业地理集聚,而交通条件的影响作用尚未凸显。
[Abstract]:Gini coefficient, barycenter model, ESDA method and spatial econometric analysis model are used. The spatial and temporal characteristics of fishery geographic agglomeration in China from 1988 to 2013 and its influencing factors were investigated. It was found that there were significant geographical agglomeration phenomena and spatial autocorrelation characteristics in Chinese fishery. The range of the geographical center of gravity of fisheries is mainly distributed in Anhui, Jiangxi, Hubei and Soviet provinces along the middle and lower reaches of the Yangtze River. The number of hot spots and sub-hot spots in the fishery spatial association pattern decreased by nearly half in the past 26 years, and the number of cold spot areas and sub-cold spot areas increased, but the types of areas that did not change were the main ones. The basic characteristics of the changing type areas are the gradual weakening of the echelon, and the distribution of the concentrated segments and the gradient shift of each type area are not obvious. (3) the fishery has positive inter-provincial spatial spillover effect. In coastal areas, industrial externality, human capital, consumption demand, urbanization rate, technological level, industry extroversion and government intervention will all affect the geographical agglomeration of fisheries in China, but the influence of traffic conditions has not been highlighted.
