专业村集聚时空演化特征——以河南太行山麓为例

专业村发展正在经历由点到面的集聚发展阶段,逐渐呈现出集聚态势。在对专业村集聚概念界定的基础上,从外延（空间集聚）和内涵（功能集聚）两方面分析,构建测度模型,并以河南太行山麓集聚区为例进行实证分析,得出如下结论：① 专业村集聚是一个动态概念,其空间范围和内部功能都在不断发生变化。② 空间演化遵循“中心—外围”路径。实证分析表明河南太行山麓专业村存在空间集聚,且集聚程度不断提高;集聚范围逐渐扩大,并沿“中心—外围”路径扩散。③ 功能演化受亲缘、地缘、业缘联系的影响,联系密度逐渐增强。实证结果显示,河南太行山麓专业村集聚网络密度和集中度均上升,表明其网络联系紧密度逐渐增强,集聚优势凸显;中心势和中心度有所下降,表明专业村之间的支配关系更均衡,呈现由两极分化到层级发展的趋势;功能演化经历了低水平均衡阶段、极核阶段、高水平均衡阶段。

Spatio-temporal evolution of specialized villages agglomeration: A case study of foothills of Taihang Mountains in Henan

The development of specialized villages is evolving from a scattered point pattern to a clustered planar form, showing a trend of gradual agglomeration. We analyzed the formation and evolution of Specialized Villages Agglomeration (SVA) at the foothill of Taihang Mountains from the aspects of both internal functions and external influences. Based on the concept of SVA, empirical models were constructed as an example for further analysis. Findings from our study include: (1) SVA is a dynamic concept with constantly changing spatial extent and internal functions. (2) The evolution of SVA follows the path of the "center-periphery" model, which is verified by empirical analyses. The calculated global spatial autocorrelation shows that there is a spatial clustering of SVA at the foothills of Taihang Mountains area in Henan and the degree of agglomeration is increasing. The result of optimized hot spot analysis further confirms an expanding spatial extent of the agglomeration, where the hot spot and sub-hotspot areas have been expanding. The evolution of SVA seems to follow the "center-periphery" spatial structure in its diffusion process. (3) The evolution of SVA is mainly affected by the indigenous, geographical, and industrial factors, which strengthen the interactions and interconnection among specialized villages. The empirical analysis shows that SVA at the foothills of Henan Taihang Mountains area continues to grow over time with tightening economic linkages between specialized villages and the growing overall economic development in the area. That is to say, the influence of the whole network of SVA to the node gradually increased in terms of economic development and cooperation. At the same time, the interaction and connection between specialized villages is gradually intensive, and the agglomeration advantage of the network is gradually prominent. Finally, there is also an observable trend of decreasing dominance by the growth poles in the agglomeration, making SVA a more balanced cluster than before.
