長(zhǎng)江經(jīng)濟(jì)帶生產(chǎn)性服務(wù)業(yè)集聚的空間溢出效應(yīng)——基于行業(yè)和地區(qū)分異的空間杜賓模型研究

摘要： 基于長(zhǎng)江經(jīng)濟(jì)帶2006—2015年108個(gè)地級(jí)及以上城市的面板數(shù)據(jù),運(yùn)用空間杜賓模型對(duì)其生產(chǎn)性服務(wù)業(yè)集聚的空間溢出效應(yīng)進(jìn)行實(shí)證研究。結(jié)果表明,長(zhǎng)江經(jīng)濟(jì)帶經(jīng)濟(jì)發(fā)展和生產(chǎn)性服務(wù)業(yè)集聚水平具有顯著的空間相關(guān)性,生產(chǎn)性服務(wù)業(yè)集聚能顯著促進(jìn)本地區(qū)經(jīng)濟(jì)增長(zhǎng),但過(guò)度集聚會(huì)對(duì)周邊地區(qū)經(jīng)濟(jì)產(chǎn)生抑制作用。進(jìn)一步研究發(fā)現(xiàn):高端生產(chǎn)性服務(wù)業(yè)集聚能夠有效促進(jìn)東、中部地區(qū)的經(jīng)濟(jì)增長(zhǎng),同時(shí)在東、西部地區(qū)存在顯著的正向空間溢出效應(yīng);低端生產(chǎn)性服務(wù)業(yè)集聚對(duì)中、西部的本地區(qū)經(jīng)濟(jì)增長(zhǎng)有顯著促進(jìn)作用,對(duì)西部地區(qū)經(jīng)濟(jì)增長(zhǎng)存在正向的空間溢出效應(yīng),但在中部地區(qū)存在負(fù)面空間溢出效應(yīng)。此外,人力資本投資、基礎(chǔ)設(shè)施改善以及外商直接投資也能促進(jìn)地區(qū)經(jīng)濟(jì)增長(zhǎng)。
The research analyzed the spatial spillover effect of its producer services agglomeration with spatial Durbin model based on the panel data of 108 cities in the Yangtze River economic belt from 2006 to 2015. The result shows that there is a significant spatial correlation between producer services agglomeration and economic growth, and the agglomeration of producer services significantly promotes the economic growth in local city, but excessive gathering has a negative effect on the economic growth in surrounding regions. Further research shows that the agglomeration of high-end producer services can significantly promote local economic growth in the eastern and middle regions, and has a significant positive spatial spillover effect in the eastern and western regions. The agglomeration of low-end producer services is beneficial to the economic growth of the middle and western regions, and has a significant positive spatial spillover effect in the western region, but has a negative spatial spillover effect in the middle region. Besides, human capital investment, infrastructure improvement and foreign direct investment can also promote regional economic growth.
