Study Of Jing-Jin-Ji District Circular Economy Integration Based On Eco-Industrial Chain

Since the reform and opening up, China economy has been developing rapidly, but italso brings a series of environmental problems. Frequent natural disasters, environmentalpollution and inefficient use of resources is not only contrary to the original intention of thesound and rapid development of the national economy, but also endanger people’s daily livesand health. Enter into the21st century, based on the “3R” principle-reduction, reuse,recycling-established circular economy is undoubtedly a fundamental way to achievesustainable development.In recent years, with the rapid development of the economy, the economic behavior of asingle regional correlation has long been not only limited to the scope of its regional. Onenature of the regional economy is external, the interaction between the region, with thepassage of the national and regional development focus from south to north, the developmentof Beijing, Tianjin and Hebei regional economic integration has become an important contentof our country regional economic development. Under the background of world city Beijing,the Beijing-Tianjin-Hebei region development facing the extensive mode of economic growth,ecological pressure on the environment, resources are depleted even more pronounced, severefog and haze for the development of traditional industries in Beijing, Tianjin and sounded thealarm. Beijing, Tianjin and Hebei geographic bordering the industrial stage of developmentand the structure is similar to the face of the resources, environment, population pressure,ecological industry chain as an effective model of coordinated development of economy andthe environment is an inevitable choice to promote inter-regional cooperation.Firstly, the domestic and international research on the recycling economy and ecologicalindustry chain overview and assessment, and introduces some basic theory used in this article:the cycle of economic theory, the theory of ecological industry chain, key species theory.Followed by analysis to identify the existing problems in the eco-industrial system ecologicalindustrial chain status quote of Beijing-Tianjin-Hebei region. Cited the current developmentof eco-industrial park. On the basis of the above analysis, the industry of the preferred Beijing,Tianjin keystone species,“built chain”“chain extender” and “make up chain” ideas and theirmeans of designing and building ecological industrial chain. Next space layout and key areas of Beijing, Tianjin and Hebei ecological industrial chain node, and promote eco-industrialpark, comprehensive utilization of resources and ecological management measures,construction mode and Countermeasures. According to the conclusions drawn by the variousindicators, Beijing, Tianjin is divided into four key industries and three ecological industrychain, and draw space layout. Finally, the combination of theory and analysis, introduced topromote the integration of Beijing, Tianjin and Hebei eco-industrial policy recommendations.
