绿洲生态水权界定及其分配

从水资源产权的角度来理解绿洲生态用水,期望为绿洲生态和环境的保护与恢复提供新的研究思路。首先对生态用水概念进行了辨析,给出了绿洲生态用水的概念;其次对绿洲生态水权从质和量两个方面进行了界定;最后提出绿洲生态水权分配的层次结构,介绍了绿洲生态用水的计算方法,重点对绿洲生态水权进行分配。从而进一步明晰了绿洲生态水权,为绿洲生态与环境的保护和恢复提供了新的理念和思路。     

农村土地承包经营权流转价格初探

从理论层面剖析了农村土地承包经营权流转价格的产权本质、构成及其实现形式。经分析认为,农地价格是农地的产权价格;土地承包经营权流转价格是土地承包经营权转移在经济上的实现形式,在实践中以现金、实物、股权等方式体现。     

农村集体建设用地流转的博弈分析与农民权益保护

农村集体建设用地流转直接影响着农民的财产性收入、关系到农村经济的发展和农村社会的稳定,已成为农村土地问题研究中的一个重要课题。该文通过构建农村集体建设用地流转博弈模型和农村集体经济组织与个体农户博弈模型,分析了不同条件下博弈的均衡解和集体建设用地流转中农民权益保护情况,并提出了相关对策建议。     

Fisheries management scenarios: trade‐offs between economic and biological objectives

An age‐structured, population biology submodel and an economic submodel with vessel‐specific dynamics were applied to a demersal fishery in the North Aegean (NE Mediterranean) that consists of three main stocks: European hake Merluccius merluccius (L.), red mullet Mullus barbatus L. and striped red mullet Mullus surmuletus L. The Mefisto model is a bioeconomic simulation model through which the biological and economic submodels (disaggregated at the vessel level) are linked by means of a fishing mortality vector. Alternative management scenarios were built and tested based on input controls, and the performance of these strategies was examined against those of current policies. Three alternative management strategies were as follows: (1) reducing the coastal fisheries' fleet units; (2) limiting the effort level (days at sea) of the trawl fleets; and (3) changing the selectivity patterns of the trawl by increasing mesh size. The results show that for all three species, any of the three management measures (input controls) would be beneficial to both the stock and the fleets (over the medium and long terms) compared with the projections over time for the status quo. Improving the selectivity of the fishing gear proved to be more beneficial than limiting nominal effort, which was in turn more beneficial than decreasing coastal fleet size.

大凌河流域初始水权分配方法比较分析

大凌河流域缺水比较严重,对其进行初始水权分配能有效配置水资源,使有限的水资源得到合理的利用,为使各地分得的初始水权更加准确,以公平性、有效性和可持续性原则为指导,建立了相应的指标体系,并分别运用模糊决策和层次分析法对大凌河流域初始水权进行分配,并对两种分配方法进行了比较分析,力求各地权重趋于合理化,最终选择层次分析法做为大凌河流域初始水权分配的方法。     

信息资源共享与知识产权保护的博弈分析

随着信息资源共享建设的拓展和深化,所涉及到的知识产权问题日益凸显出来。从多角度阐述了信息资源共享与知识产权保护两者之间相辅相成,互相制约,互相促进的关系,在此基础上提出了信息资源共享与知识产权保护的协调发展策略。知识创造和信息资源共享只有达到平衡,才能实现二者的和谐发展。
