【摘要】 本文通过构建不同的空间权重矩阵将金融集聚促进区域技术扩散的融资支持、信息传递、风险分散三大机制引入空间杜宾模型,利用2006—2018年长三角地区地级市层面数据,实证分析并比较金融集聚对长三角六大都市圈技术扩散的促进机制与成效差异。结果显示:上海大都市圈金融集聚促进技术扩散主要体现为融资支持机制,宁波都市圈主要体现为融资支持和信息传递机制,苏锡常都市圈和杭州都市圈的作用机制全面且成效显著,南京和合肥都市圈内技术扩散成效不显著;从金融子行业集聚来看,银行业集聚在各都市圈技术扩散中起主导作用,证券业集聚对苏锡常和杭州都市圈的促进成效突出,保险业集聚的技术扩散成效不显著;在各都市圈中心城市构成的Z字型辐射带域中,上海的辐射带动作用明显,南京、苏州、杭州、宁波、合肥对所处都市圈的技术扩散起到承上启下的枢纽作用。更多还原

【Abstract】 By constructing different spatial weight matrices, this paper introduces three theoretical mechanisms of financial agglomeration promoting regional technology diffusion, namely, financing support, information transmission and risk diversification, into the spatial Durbin model.Using the prefecture-level data of the Yangtze River Delta from 2006 to 2018,this paper empirically analyzes and compares the promoting mechanism and effect of financial agglomeration on technology diffusion in six metropolitan circles in the Yangtze River Delta.The results show that the financial agglomeration in the Shanghai metropolitan circle promotes technology diffusion mainly through the financing support mechanism, and that in the Ningbo metropolitan circle mainly through the financing support and information transmission mechanisms; the mechanism of Suxichang and Hangzhou metropolitan circles is comprehensive and effective, but the diffusion effect in Nanjing and Hefei metropolitan circles is not significant.From the perspective of financial sub-industry agglomeration, banking agglomeration plays a leading role in technology diffusion of each metropolitan circle, the promotion effect of securities agglomeration on Suxichang and Hangzhou metropolitan circles is outstanding, while that of insurance agglomeration in most metropolitan circles is not obvious.In the Z-shaped radiation belt region composed of the central cities of each metropolitan circle, Shanghai plays an obvious radiation driving role, and Nanjing, Suzhou, Hangzhou, Ningbo and Hefei play a pivotal role in connecting the preceding with the following to technology diffusion in their own metropolitan circle.更多还原
