Study on coupling of urban economic development and resources and environment in Beijing-Tianjin-Hebei region

Beijing-Tianjin-Hebei region integration is one of the national development strategies.Under the perspective of the goal of "carbon peak and neutrality" and stable economic growth,it is of great practical significance for Beijing-Tianjin-Hebei region and even the whole country to coordinate the urban economic development and resources and environment.However,there are few studies about it.In order to make up for this vacancy,based on the analysis of the current urban development situation,describes the evaluation index system of coordinated development of urban economy resources and environment in Beijing-Tianjin-Hebei region,by building economy-resources and environment development evaluation index system,estimates the coordinated development degree of urban economy,resources and environment in Beijing-Tianjin-Hebei region.The results indicate that the degree of interdependence and mutual restriction of Beijing City is relatively high.The coupling interaction relation,among Beijing City,Tianjin City,Shijiazhuang City,Tangshan City,Qinhuangdao City,Handan City,Baoding City and Cangzhou City,plays a greater role in the economic development and the resource environment system.However,the situation in the whole Beijing-Tianjin-Hebei region is not in excellent coordination,for further overall planning is still needed.And puts forward suggestions for coordinated development of urban economy,resources and environment in Beijing-Tianjin-Hebei region from the dimensions of strengthening market resource regulation,strengthening urban environmental protection and pollution control,promoting industrial optimization and upgrading,and establishing urban reciprocal ties,so as to promote their coordinated development.
