The Supply Capacity Improvement and Value Realization Path of Ecological Products in Beijing-Tianjin-Hebei

（School of Urban and Public Economics，Capital University of Economics and Business，Beijing 100070，China） Abstract：Ecological products are the core concept of ecological civilization construction and an important content that people need for a better life in the new era. The coordinated development of Beijing-Tianjin-Hebei is a major national strategy， and the study of ecological product supply capacity and value realization paths has important theoretical and practical significance. Based on the connotation of ecological products，an evaluation index system for the supply capacity of ecological products including 4 primary classification indicators（i.e.，ecological environment products，ecological material products，ecological cultural products，and ecological space products），8 secondary classification indicators，and 24 specific indicators has been established. The ecological product supply capacity entropy evaluation method and the ecological- health- market ecological product value comprehensive verification algorithm are used to evaluate the Beijing- Tianjin- Hebei ecological product supply capacity and value accounting；and the value realization path of Beijing-Tianjin-Hebei ecological products is explored with the help of this indicator system and the accounting result. It is found that ：the supply capacity and value of ecological products in Beijing- Tianjin- Hebei have obvious regional differences ， and the two are not completely corresponding； Chengde， Zhangjiakou，and Beijing have higher ecological product supply capacity ，Xingtai，Hengshui，Langfang，and Handan have lower ecological product supply capacity ；ecological product value in Chengde and Zhangjiakou accounts for a very high proportion of the GDP，while that of Beijing and Tianjin is lower ；and for different kinds of ecological products，we should adopt different value realization path，namely，the path of government- led and market- support is suitable to public ecological products，the path of government- support and market- led is suitable to business ecological products ，and the path of government-guided and market-operation is suitable to equity-based ecological products. We should improve the supply capacity and promote value realization from such four aspects as rationally dividing the types of ecological product supply areas， enhancing the market role of ecological products，improving the ecological protection compensation system ，and accelerating the construction of regional cooperation system for ecological product supply in Beijing-Tianjin-Hebei.

Key words：ecological products；supply capacity；value realization；the coordinated development of Beijing-Tianjin-Hebei； the harmonious coexistence between humankind and nature
