【摘要】：笔者以南京、镇江、扬州(宁镇扬)地区为研究对象,基于地理加权回归模型探讨区域经济发展空间及产业特征。结果表明:(1)与传统OLS参数估计相比,地理加权回归模型因有效显示空间发展非稳定性而更有利于表征空间作用微观机理;(2)宁镇扬三市之间经济发展存在空间同构性及异质性,但区域间互动性差,"辐射遗漏"现象明显;(3)从产业结构特征看,区域产业结构相似系数不断上升,趋同性明显,然而,由于区域同城化发展水平低,重复建设、资源浪费及恶性竞争现象严重。未来产业发展应进一步破除行政壁垒,整合区域资源、提升区域综合实力,加强产业合作、促进产业集聚、推动错位发展,最终实现区域同城化。
[Abstract]:Taking Nanjing, Zhenjiang and Yangzhou (Ningzhenyang) as the research objects, the author discusses the regional economic development space and industrial characteristics based on the geographical weighted regression model. The results show that compared with the traditional OLS parameter estimation, the geo-weighted regression model is more favorable for characterizing the microscopic mechanism of spatial action because of the instability of spatial development.) there is spatial isomorphism and heterogeneity in the economic development of Ningzhenyang city. However, the interaction among regions is poor, and the phenomenon of "radiation omission" is obvious.) from the characteristics of industrial structure, the similarity coefficient of regional industrial structure is rising, and the convergence is obvious. However, because of the low level of development of regional urbanization, the repeated construction, Waste of resources and vicious competition are serious. The future industrial development should further break down administrative barriers, integrate regional resources, enhance regional comprehensive strength, strengthen industrial cooperation, promote industrial agglomeration, promote dislocation development, and finally realize the regionalization of the same city.
