We choose the coordination degree of Yunnan province from 2012 to 2015. The regional cultural and economic development in Yunnan's frontier are analyzed so that we can provide the reference for the sustainable development of Yunnan's frontier and realize the coordinated development of culture in Yunnan's frontier and economic system in order. The results show that the culture and economy in Yunnan's frontier are coupled with formation of the coordinated development of culture and economy; economic development is the main reason to promote the coordinated development of culture and economy in Yunnan's frontier, and it contributes to the main force of improving the coordinated development of evolution types; the coordinated development degree of the overall level is low and still in the China's backward level.展开更多

By building the coupling evaluation index system of the water resources-economy-ecology-society system,quantitative evaluation and analysis of the coupling coordination of the water resources-economy-ecology-society system from 2001 to 2014 were conducted. The results showed that benefit indexes of economic system and social system grew rapidly,while benefit indexes of water resources system and ecosystem fluctuated smoothly from 2001 to 2014; coupling state of the whole system was at rival stage,and coupling coordination was reluctant coordination type,and the coupling index was slightly higher than the coupling coordination index. Moreover,it showed that the more the coupling systems,the lower indices of coupling and the coupling coordination.展开更多

The major function oriented zoning plays a role in spatial coordination mainly by spatial guidance and restriction, so, the proposal of major function oriented zoning gives a new train of thought to generate a coordination evaluation of economy-society and the resource-environment system. From the view of major function oriented zoning that considers resource environmental bearing capacity, existing development density and development potential, this paper constructs an index system and model of coordination evaluation with a case study on Pearl River Delta. The results have shown: (1) It can reveal the conflicts of economic-social development and resource-environment quality to accurately consider resource environmental bearing capacity, existing development density and development potential; (2) The coordination degree between social-economy system and resource-environment system in Pearl River Delta continued to decline in the past 10 years. The spatial extent of coordination evolves from coordination in the whole Pearl River Delta to imbalance in the core areas, and at present, the uncoordinated areas have already diffused from core areas to the outlying regions; (3) Most regions of the Pearl River Delta are in uncoordinated condition when considering the coordination degree of economic-social development and resource-environment quality, not as coordinated as some scholars considered.展开更多

The results show that Zhejiang's CDD has kept increasing steadily after its slight drop in 1998. Finally, four measurements are proposed to promote sustainable development, including increasing and equalizing region's environmental investment, changing pollution-intensive export structure to avoid restricting the whole industrial structure, restricting simple spatial translocation of high-material consumption, high-energy consumption and high-pollution industries, etc.展开更多

To take progress as the sustainable development way, save resource and improve environment, our nation has been advocating to construct the cycle economy and saving-oriented society. Taking the remanufacturing engineering as the representative, the “4R” rule (Reduce, Reuse, Recycle and Remanufacture) is the important measure to get the goal. Remanufacturing engineering is the industrialization of high-tech maintenance of the waste and worn productions, and is one of the most active factors in “4R”. The development of high and new technology takes the important effect to promote the remanufacturing engineering.展开更多

It also points out that the essence of sustainable development is theharmonious relation between economy and the ecosystem. Therefore, the resources allocation should be considered from theaspect of the market demand and the aspect of the supply of the ecosystem. That is to say, firstly, the scale and pace of economygrowth must be adapted to the supply capability of the ecosystem under the current technology. Secondly, based on the supplyability of the ecosystem, we should make it clear how to make limited resources allocation attains equilibrium between marketsupply and demand. The paper clarifies that in the mode of knowledge economy; we may transform the way of economy growth,form optimum economy structure, change the base of resource supply, strengthen the supply capability of ecosystem, expandthe production-possibility frontier, and finally accomplish the eco-economy coordinated development through the innovationof institution and technology. The essence of sustainable development and the sustainable characteristics of knowledgeeconomy that were discussed above determine that knowledge economy is an economy of sustainable development.展开更多

Based on the analysis on present condition and future trends of economic development in Tianjin and the quantification of various evaluation indices, the author applies integrated index valuation model to valuate the harmonious development of economy-environment of Tianjin. The results show that the coordinated degree of economy-environment would drop down in the future, from 0.95(superior level of harmonious development) in 2000 to 0.59(inferior level of harmonious development) in 2015, under the circumstance of the current economic development mode. The level of comprehensive development of Tianjin also presents to descend. Based on the analyzing of status and future trends of environment-economy coordinated development, the paper puts forward the countermea- sures such as industry structure adjustment, increasing the level of environmental protection investment, strengthening the enforcement of environmental policies to improve the coordinated development of environment-economy in Tianjin municipality.展开更多

Apart from the loss of life, the present conflicthas tremendous impacts on the environment, economy, and society. The conflict provoked a ripple of events withimplications at the global level, especially in energy and food. The escalation of this conflict is imposing severethreats to achieving the United Nations (UN) Sustainable Development Goals (SDGs) not only to the countries di-rectly involved in the conflict but also to other countries, especially the developing ones that are more vulnerableto the economic crisis. In this editorial, we assessed the impacts of the Russian-Ukrainian conflict on BiophysicalSDGs, Social SDGs, Economic SDGs and Partnership for the Goals SDG that consider all the previous dimensions.The Russian-Ukrainian conflict’s impact on the SDGs is variable. Biodiversity SDGs are mainly affected at theregional level (Russia, Ukraine, surrounding and European Union countries). Society SDGs are affected at local(e.g., SDG3 good health and wellbeing;SDG4 quality education) and global (e.g., SDG2 zero hunger) levels. Fi-nally, the Russian-Ukrainian armed conflict has world-level implications for the economic SDGs. Nevertheless,the ongoing conflict’s impacts are not entirely understood, and several uncertainties exist. Peace is needed toachieve the UN’s SDGs in 2030.展开更多
