分析黑河分水政策制度变迁过程,辨析其中利益相关者作为相互博弈的主体各自所面临的成本-收益处境,探讨造成各个主体不同的偏好取向的更深层次社会政治经济环境根源,无疑能从更高的层面理解整个制度走向,为更好地改进政策制度提供有益... 分析黑河分水政策制度变迁过程,辨析其中利益相关者作为相互博弈的主体各自所面临的成本-收益处境,探讨造成各个主体不同的偏好取向的更深层次社会政治经济环境根源,无疑能从更高的层面理解整个制度走向,为更好地改进政策制度提供有益的启示。总结1960年以来黑河流域分水政策制定实施的历史,提出了分水政策制度变迁的一个可能的模型,即一个将中央政府、地方政府和居民(尤其是农村居民)三元主体纳入的完整的、一般性的制度变迁模型。旧制度结构的变迁和新制度结构的得出,是三元主体在成本约束下最大化自身利益的策略下,对制度选择空间本身或在制度选择空间内部进行多次博弈的结果。三元主体各自面临的成本-收益,规定了他们在制度变迁中的地位与策略行为。最后,对分水政策制度的改进提出了建议。 展开更多

This project investigates the hypothesis for keeping the environment safe by using human resources at the local government level. Strategic decision-making in the management of human recourses in the field of environmental protection is crucial for the countries in transition. Lack of financial and technological resources can be compensated with other potentials. Therefore, it is necessary to emphasize the decision-making process. Optimization of the existing resources under real conditions is needed in order to get better results of the implementation of adopted strategies. As an example, the scheme of optimal solution based on PROMETHEE method (multi-criteria method of optimization) is given. 展开更多

The present research is based upon a comprehensive survey which discusses the slightly tolerable water level of Balaton between 2000 and 2003. The low water level of the extreme period caused considerable problems in recreation. Our goal was to investigate the possible water transfer policies and the water level regulation policy of Lake Balaton by applying the dynamic programming of Markov chains. This iteration supports the cost-benefit analysis of different scenarios and also provides information about the best water governing policy. As a basis of our scientific analysis, Markov chains were created by ARMA (autoregressive moving average) synthetic data generator. Profit was joined to each transition-probability for the economic analysis. In our case the profit was negative, because the harmful effects of the low water level should be estimated, which is based on the calculated willingness-to-pay for improving the water quality of Lake Balaton. In addition, the profit includes the cost of different water supplement scenarios. After computer programming, the method proved to be an efficient tool to buttress the cost-benefit analysis of water supplement scenarios. The result highlights the importance of further climate change monitoring. Calculation confirmed water transfer to be cost-effective, yet scenarios with less ecological risk are also effective, thus preferable. 展开更多
