成渝经济圈R & D空间溢出网络结构研究

利用修正空间引力模型和社会网络分析法，对成渝经济圈R&D空间溢出网络结构进行探索。研究发现，成渝经济圈R&D分布的地缘邻近性显著，南北贯线的地缘邻近性明显强于东西贯线的空间相似性；区域R&D空间溢出的网络结构具有“主核-多中心”特点，“强链”和 “弱链”区域分异明显；区域内R&D空间溢出的出度和入度两极分化严重，区域间R&D空间溢出不完全服从区域经济发展水平势差所带来的方向性；整体来看，区域内R&D空间溢出四大凝聚子群基本契合区域经济整合的边界分异。

The Spatial Diffusion Network Structure of R&D in Chengdu-Chongqing Economic Zone

On the basis of bellows theory, using the space modified gravity model and social network analysis, the study explored the spatial diffusion network structure of R&D in chengdu-chongqing economic zone. The study found that the R&D distribution of chengdu-chongqing economic zone have a remarkable geopolitical proximity, the geographical proximity of north-south line is stronger than east-west line, the spatial diffusion network structure have the "main core-multicenter" feature, regional differentiation of "strong chain" and the "weak link" is obvious, the outdegree and indegree of spatial diffusion have serious polarization, the spatial diffusion direction is not fully compliant with the potential difference of the city economic development level, the cohesion subgroups of the spatial diffusion fit the border of regional economic integration.
