【摘要】：長(zhǎng)江經(jīng)濟(jì)帶區(qū)域協(xié)同增長(zhǎng)的關(guān)鍵在于明確沿江城市群內(nèi)部城市間產(chǎn)業(yè)聯(lián)系對(duì)其經(jīng)濟(jì)產(chǎn)出的影響。城市群內(nèi)部城市間的產(chǎn)業(yè)聯(lián)系會(huì)加強(qiáng)其間的知識(shí)溢出并分享超額利潤(rùn),從而影響城市群的經(jīng)濟(jì)產(chǎn)出。分析城市群內(nèi)部城市間產(chǎn)業(yè)聯(lián)系對(duì)經(jīng)濟(jì)產(chǎn)出的影響機(jī)制,構(gòu)建理論模型。針對(duì)傳統(tǒng)引力模型的不足,采用行業(yè)間投入產(chǎn)出引力模型(IIG模型)估算了2001-2015年間長(zhǎng)江經(jīng)濟(jì)帶沿線(xiàn)城市群的產(chǎn)業(yè)聯(lián)系,通過(guò)產(chǎn)業(yè)聯(lián)系修正人力資本的有效性。采用非參數(shù)協(xié)方差矩陣估計(jì)方法驗(yàn)證了理論模型。分析結(jié)果表明,以傳統(tǒng)引力模型估算產(chǎn)業(yè)聯(lián)系時(shí),無(wú)法驗(yàn)證產(chǎn)業(yè)聯(lián)系對(duì)經(jīng)濟(jì)產(chǎn)出影響的正面作用,而使用IIG模型估算產(chǎn)業(yè)聯(lián)系時(shí)則能驗(yàn)證,即驗(yàn)證了理論模型,也說(shuō)明了IIG模型對(duì)引力模型改進(jìn)的意義。
[Abstract]:The key to the coordinated growth of the Yangtze River economic belt lies in making clear the influence of the industrial relationship between cities in the urban agglomeration along the Yangtze River on its economic output. The industrial relationship between cities in urban agglomeration will strengthen the knowledge spillover and share the excess profit, which will affect the economic output of urban agglomeration. This paper analyzes the influence mechanism of industrial connection between cities in urban agglomeration on economic output, and constructs a theoretical model. Aiming at the shortage of traditional gravity model, the paper estimates the industrial linkage of urban agglomeration along the Yangtze Economic Belt from 2001 to 2015 by using the Input-Output Gravity Model (IIG), and modifies the effectiveness of human capital through industrial linkage. The nonparametric covariance matrix estimation method is used to verify the theoretical model. The results show that the positive effect of industrial linkages on economic output can not be verified by traditional gravity model, but the theoretical model can be verified by using IIG model to estimate industrial linkages. The significance of IIG model to the improvement of gravity model is also explained.
