Circular economy (CE) has been put fonvard as an important environmental and resource strategy in China.Aiming at the high utilization rate of resources and reduction of pollutants,CE means to realize a shift of fundamental paradigm.With the mode of production and consumption from linear to recycling model,the promotion requires transdisciplinary researches which integrate technological,ecological,social-cultural and other sciences.The present study focuses on the implementation of circular economy from an institutional perspective.Institution acts as a crucial factor by providing incentives for technical innovation,leading investment orientation and determining policy effectiveness,etc.This paper mainly discusses about: firstly,the feature of institution,institutional changes and institutional innovation is articulated,together with eco-industrial park strategy,extended producer's responsibility and dematerialization principle as innovative institutional arrangements; secondly,as policy plays great role on institutional changing process,the mechanism of policy implementation is needed to be related; as a result,coevolution of institutions and policies is thus presented; at last,a pilot attempt is made to find out some operational avenues in accomplishment of CE through both theoretical and practical methodology,special resolutions are put forward after some projecting difficulties and dilemmas in China are described. 展开更多
