According to service objects of urban green spaces, 6 relationship fields were classified, specifically, global ecology, regional environment, regional health, basic life, spiritual life and material life, a basic framework for evaluating economic, ecological and social benefits of urban green spaces was proposed.展开更多

Local governments compete to declare for higher-leveled and large-scaled economic regions to obtain more economic resources and policy support in the way of policy game. The author argues that the regionalization chaos is attributed to the reason that the present theoretical support for economic regionalization overemphasizes the economic growth brought about by the economic regionalization but ignores the effect of transaction cost, which leads to constraint loss on the economic regionalization theory analysis framework. Then, the introduction of economic regionalization analysis framework based on the conflicts between scale expansion and transaction costs would establish equilibrium conditions to set up a moderate scale development for economic regions. The author hopes that the acceptance of this framework into the economic regionalization decision-making system would give guidance for making more appropriate regionalization decisions.展开更多

文摘Based on the meaning of economic theory as well as analysis of relevant characteristics of watershed environmental management,a watershed environmental management framework will be created,with building systems of theory,principles,methods,and supporting measures.Through the general structure,the watershed environmental management system design can be explored to optimize the allocation of resources and achieve coordinated development of watershed economic growth and environmental protection.
文摘Researchers' understandings of economic, ecological and social benefits of urban green spaces were discussed from many perspectives, connotations of such three major benefits were redefined, existing problems in the present evaluation were analyzed. According to service objects of urban green spaces, 6 relationship fields were classified, specifically, global ecology, regional environment, regional health, basic life, spiritual life and material life, a basic framework for evaluating economic, ecological and social benefits of urban green spaces was proposed.
