基于投入产出模型的成渝地区产业溢出和反馈效应研究

Research on Industrial Spillover and Feedback Effect in Chengdu-Chongqing Region Based on Input-Output Model

摘要: 采用两区域投入产出模型，编制成渝区域间投入产出表，运用投入产出分析方法对成渝地区经济发展的区域内乘数效应、区域间溢出效应和区域间反馈效应进行测算、分析和比较。研究表明：四川省区域内产业联系强度更强，重庆市区域间产业联系强度更强，成渝地区在经济发展中存在产业同质竞争和市场分割现象。因此两地应发展优势产业，完善核心产业链配套，推动市场一体化建设。

Abstract: The two-regional input-output model is used to compile the inter-regional input-output table of Chengdu and Chongqing, and the input-output analysis method is used to measure, analyze and compare the intra-regional multiplier effect, interregional spillover effect and interregional feed-back effect of economic development in Chengdu and Chongqing. The research shows that the intensity of intra-regional industrial linkages in Sichuan Province is stronger, and the intensity of inter-regional industrial linkages in Chongqing is stronger. Chengdu-Chongqing region has industrial homogeneous competition and market segmentation in economic development. Therefore, the two places should build a high-end core industrial chain, promote the integrated development of the market, and strengthen policy coordination and cooperation.
