基于耦合理论的煤炭资源型城市循环经济路径研究

煤炭资源型城市在发展建设过程中走的是一条赶超型工业化道路,存在支柱产业单一,资源综合利用程度低,环境压力大,后备资源不足,城、矿关系不顺,竞争力不强,城市负担过重等问题,其都是制约资源型城市转型发展的瓶颈。所有煤炭资源型城市都面临"煤竭城衰"的潜在威胁,必然要经历"建设—繁荣—衰退—消亡或转型"的过程。如何实现城市的可持续发展,是所有煤炭资源型城市急需考虑的问题。基于产业耦合理论,认为煤炭资源型城市因地制宜,发展循环经济产业集群,是实现可持续发展的最佳战略选择。     

How and when do purchasers successfully contribute to the implementation of circular purchasing: A comparative case-study

The transition towards a circular economy puts pressure on organizations to purchase in a circular manner. The aim of this research is to investigate the role, behaviors, and characteristics of purchasers in the circular purchasing process, and the contextual factors that influence circular purchasing. To address this aim, we interviewed purchasers, supervisors and policy makers of seven Dutch organizations. The results of the comparative case-study show that the main roles of the purchaser are those of coordinator, facilitator and advisor, and that the successful circular purchaser can best be described as intrapreneurial, sustainability-minded and knowledgeable about the circular economy. Purchasers are successful in implementing circular purchasing when they share responsibility with budget holders and when they are part of organizations that have processes in place to ensure the inclusion of circularity in their purchasing projects. The drivers that influence the success of circular purchasing can be described as creating a sense of direction and grasping the complexity of the circular economy. Furthermore, the market, organizational, legal, conceptual and cultural constraints that limit the success of circular purchasing were identified.     

促进贵州循环经济发展的税收政策取向分析

改革开放以来,贵州经济发展取得了显著的成就,但是经济的发展方式没有得到根本的转变。随着优势原材料、能源等产业的加速发展,资源与环境矛盾将日益突出,发展循环经济成为贵州实现经济和生态双赢的必然选择。税收政策作为国家宏观调控的重要工具,在促进循环经济发展方面无疑具有重要作用。在概括现阶段促进循环经济发展的税收政策的主要内容基础上,分析了现行税收政策存在的不足,提出进一步促进贵州循环经济发展的税收政策建议。     

两种生产力与发展循环经济

生态生产力是社会生产力的基础,社会生产力又直接影响生态生产力,二者组成一个有机的系统,必须协同共进。循环经济是对自然生态系统循环的一种模拟,既可以有效地发掘和利用生态生产力为社会生产力的发展提供动力,又可以在发展社会生产力的同时有效地保护和提高生态生产力,是发展生产力的现实选择。文章从生产力理论的角度分析了我国目前发展循环经济的可行性与必要性,并提出相应的发展建议。
