区域产业链的构建和发展对于区域经济一体化发展具有重要意义。本文先从理论上分析产业链对于促进区域经济一体的机理,然后运用产业链复杂度测度方法和产业链联系度方法,基于2002年、2007年和2010年京津冀区域六部门区域间投入产出表,分析京津冀区域产业链。研究结果表明,京津冀地区各省市间的产业链CI值越来越高,说明随着京津冀区域一体化水平的提高,京津冀区域产业链发展也越来越好。据此,本文针对京津冀一体化提出了相应的政策建议。
The construction and development of regional industrial chain is of great significance to the integrated development of regional economy. This paper first analyzes the mechanism of industrial chain in promoting regional economy, and then uses the measurement method of industrial chain complexity and industrial chain connection degree method. Based on the analysis of input-output between the six sectors of Beijing-Tianjin-Hebei region in 2002, 2007 and 2010 A table to analyze the Beijing-Tianjin-Hebei regional industrial chain. The results show that the value of CI in industrial chains between provinces and municipalities in Beijing, Tianjin and Hebei is getting higher and higher, indicating that with the improvement of regional integration in Beijing, Tianjin and Hebei, the development of regional industrial chains in Beijing, Tianjin and Hebei is getting better and better. Accordingly, this article puts forward the corresponding policy recommendations for the integration of Beijing, Tianjin and Hebei.
