長三角城市群服務(wù)業(yè)空間分工及其經(jīng)濟(jì)聯(lián)系

摘要： 基于長三角城市群26個地級及以上城市服務(wù)業(yè)的相關(guān)數(shù)據(jù),采用產(chǎn)值密度、產(chǎn)業(yè)專業(yè)化系數(shù)、行業(yè)相對專業(yè)化指數(shù)測度服務(wù)業(yè)空間分工特征,并通過服務(wù)業(yè)與外界經(jīng)濟(jì)活動密切交流產(chǎn)生的城市流強(qiáng)度考察城市間經(jīng)濟(jì)聯(lián)系。結(jié)果表明:長三角城市群服務(wù)業(yè)的空間演化效應(yīng)開始顯現(xiàn),形成"南京-鎮(zhèn)江-常州-無錫-蘇州-上海-嘉興-杭州-寧波-舟山"的"Z"形走廊地帶;服務(wù)業(yè)分工專業(yè)化程度提高,空間分工愈加明確;各城市服務(wù)業(yè)優(yōu)勢行業(yè)出現(xiàn)變化,但存在一定的產(chǎn)業(yè)同構(gòu)現(xiàn)象,未來要打破行政壁壘,著力培育新發(fā)展方向,形成新經(jīng)濟(jì)增長點;各城市均具有一定的外向輻射能力,但差異較大,要通過發(fā)揮高城市流強(qiáng)度城市的輻射帶動能力、實施產(chǎn)業(yè)轉(zhuǎn)移、促進(jìn)服務(wù)業(yè)有效集聚、強(qiáng)化交通網(wǎng)絡(luò)建設(shè)等措施,促進(jìn)城市群內(nèi)部的合理分工和功能互補(bǔ)。
This article a dopts product value density, industry specialization coefficient and industry relative specialization index to measure the characteristics of spatial division of service industry based on the related service industry data of 26 cities at Prefecture Level or above in Yangtze River Delta region. Furthermore, urban flow intensity streaming from the close communications between service industry and external economic activities is used to investigate the economic connections among cities. Research shows that the spatial evolution effect of service industry of Yangtze River Delta region began to appear and developed into a Z-shaped corridor zone of "Nanjing-Zhenjiang-Changzhou-Wuxi-Suzhou-Shanghai-JiaxingHangzhou-Ningbo-Zhoushan". The level of division and specialization of service industry has been improved, and the spatial division has been more explicit. There are certain changes that have arisen in the superior sectors of service industry, but there is a certain phenomenon of industry isomorphism. In the future, it is necessary to break administrative barriers, cultivate new development direction and form new economic growth point. Although all cities have a certain degree of outward radiation capacity, there are still existing significant differences among them. Cities can use those measures to promote rational division of labor and function complementation: such as exerting their radiative power of cities with high city flow intensity, implementing industrial transfer, promoting effective agglomeration of service industries, and strengthening traffic network construction.
