| As the strategic status of ecological civilisation is raised,ecological compensation is widely used as an important means of regulating ecological environmental protection and economic development.At present,the practice of ecological compensation in China has moved from the pilot stage to the stage of full-scale implementation,and a number of national policies have been issued to make special arrangements for ecological compensation work.In the context of the synergistic development of Beijing,Tianjin and Hebei,the construction of ecological compensation mechanisms in the region has been receiving high attention,but so far,the ecological compensation mechanism in Beijing,Tianjin and Hebei has not yet been fully established.A study on the optimisation of the ecological compensation mechanism in the Beijing-Tianjin-Hebei region is of great importance in promoting the healthy and sustainable development of the regional ecological environment and realising the integration of Beijing-Tianjin-Hebei.Combining existing theoretical achievements such as public goods theory and property rights theory,the thesis systematically reviews the research progress at home and abroad and elaborates on core concepts such as ecological compensation and ecological compensation types,providing logical premises and theoretical foundations for the subsequent research.The thesis systematically describes the current situation of the ecological compensation mechanism in the Beijing-Tianjin-Hebei region from two perspectives: existing legal protection and policy support,and the construction of ecological compensation organizations.It also discusses the shortcomings of the ecological compensation mechanism in the Beijing-Tianjin-Hebei region,using questionnaires and case studies,focusing on five core elements of the ecological compensation mechanism:ecological compensation subject,compensation object,compensation method selection,compensation standard setting and compensation system guarantee,to pave the way for later analysis.Based on the analysis of the existing practice progress and questionnaire data,it is concluded that there are still some problems in the ecological compensation mechanism in the Beijing-Tianjin-Hebei region,including a single form of compensation subject,unfair allocation of object rights,a single compensation method,low compensation standard and the lack of systematic institutional design.In-depth discussions are conducted in the light of existing theoretical results and research,and the causes of the problems are analysed as a lack of enthusiasm for participation by social forces,an inadequate consultation mechanism for ecological compensation,insufficient use of diverse compensation methods by the government,an inadequate investment mechanism and standard system for ecological compensation funds,and a backward environment for the construction of the legal system for ecological compensation.Accordingly,suggestions for optimising the ecological compensation mechanism in the Beijing-Tianjin-Hebei region are put forward,namely,building a diversified ecological compensation mechanism in the Beijing-TianjinHebei region,improving the coordination mechanism for ecological compensation in the Beijing-Tianjin-Hebei region,exploring diversified ecological compensation methods in the Beijing-Tianjin-Hebei region,establishing a sound ecological compensation fund input mechanism and standard measurement system in the Beijing-Tianjin-Hebei region,and strengthening the top-level design of ecological compensation laws in the Beijing-TianjinHebei region. |
