中国高技术产业国内循环价值链省域分工地位与网络位置研究

Research on the Provincial Division Status and Network Location of China’s High-tech Industry in Domestic Circulation Value Chain

省域基于自身分工地位嵌入国内循环价值链网络进行分工协同,是构建新发展格局的重要支撑。兼顾增值能力与劳动生产率两个维度,设计提出一个评测高技术产业省域分工地位的新框架,并结合国内循环价值链网络结构图对不同高技术产业的省域嵌入位置进行对比分析。研究结果表明:(1)沿海省域在价值链分工地位优势的强度与广度均最为显著,内陆省域的分工地位优势则集中于上游部门。(2)江苏、上海、广东、内蒙古在高技术产业国内循环价值链均占据显著的分工地位。(3)制造业部门的分工地位凸显,而服务业部门分工地位则相对较低。(4)以高技术服务业为代表,中国高技术产业国内循环价值链上游部门的分工地位省域首位度较高。同时,国内循环价值链产业部门分工地位省域首位度与其整体分工地位之间未显示紧密关联性。

Collective teamwork among provinces positioned along the domestic circulation value chain according to their respective status in the division of labour is an important support for China to build a new development pattern.Taking into account two dimensions:value-add capacity and labor productivity,this paper designs a new framework for evaluating the provincial division status in domestic circulation value chain of China's high-tech industry,and compares and analyzes the locations where different high-tech industries are embedded across provinces in combination with domestic circulation value chain network structure.The research shows that coastal provinces' division status is most advantageous in both strength and breadth,while inland provinces' division advantage is concentrated in the upstream sector;Jiangsu,Shanghai,Guangdong and Inner Mongolia have a significant division status in the domestic circulation value chain of high-tech industries;the division status of the manufacturing sector is prominent,while that of the service sector is relatively weak;the provincial primacy ratio of the upstream sector's division status in domestic circulation value chain is high and this is especially typical of the high-tech service industry.In addition,there is no close correlation between the provincial primacy ratio of the industrial sector in the domestic circulation value chain and its overall division status.
