制度变迁与制度绩效：来自中国农地的分析

制度经济学的理论可以用来分析中国农地制度变迁及其绩效。寻求最佳的绩效一直是制度变迁的终极目标。50多年来中国农地制度变迁一直在实践着一种效率更高的制度对另一种制度的替代。中国未来农地制度的变迁必须遵循土地产权制度安排的稳定性和资源最佳配置效应原则、激励机制健全原则、农地制度安排的渐进式原则和农村社会保障体系健全原则。     

Farmers' perception on self created water management rules in a pioneer scheme: The mula irrigation scheme, India

During the past two decades with farmer participation in irrigation management moving to center stage, the traditional view of having a centralized control over the water resources for better management has changed. Nevertheless, success of irrigation management transfer depend on a whole set of institutional arrangements or the rules-in-use and the willingness of the users to comply and enforce and/or change the rules in the light of changing circumstances. There are many institutional analyses of water sector, much of them touch on law, policy and administration, and characteristics of the users. The present paper is based on the study carried out to examine the institutional arrangements in one of the water users association that was first in the Maharashtra state. It focuses on the institutional arrangements governing water use and distribution and attempts to elicit the perceptions of the members regarding the rules-in-use. The findings reveal that the WUA has been successful in devising and enforcing the rules for water distribution, fee collection and conflict resolution for over a decade. However, current socio-economic developments such as political heterogeneity have required explicit conflict resolution mechanisms. These issues have now become issues demanding immediate attention and may be use of existing courts or legal institutions to help the WUA sustain in future.

EXTERNALITIES,INSTITUTIONS AND THE LOCATION CHOICES OF SHELLFISH PRODUCERS: THE CASE OF BLUE MUSSEL FARMING IN THE MONT-SAINT-MICHEL BAY (FRANCE)

ABSTRACT

Most marine aquaculture activities remain strongly dependent on coastal ecosystems. In the case of shellfish farming, this dependency is related mainly to water quality and to the various ecological interactions resulting from the dynamics of coastal food webs. Such ecological constraints have influenced the overall evolution of blue mussel farming in the Mont-Saint-Michel Bay, leading producers to negotiate collective arrangements regarding production capacity and techniques and to develop production strategies at the farm level. This article presents an analysis of the location choices of mussel farmers in the Mont-Saint-Michel Bay based on an empirical investigation conducted in 2002. A typology of farms with respect to their land structure is developed in which some farms choose to concentrate their activity in a single part of the bay while others distribute their activity more widely. Determinants of the location choices of each farm category, including distance to port, natural productivity differentials, and predation of mussel stocks, are analyzed. The role of the institutional arrangements allowing mussel farmers to develop these location strategies is also discussed.

关于控制盐渍化的制度安排——以土耳其为例

在高度集权的非市场决策的环境下,有效需求是由政治决策者提出的。他们的决定只出于政治方面的考虑,与当地需求无关。政府方面的有效控制盐渍化服务由于其较高的多变性和交易成本而受到妨碍,而将它们最小化的行政程序本身又导致下水位的上升。有了自治的用水户协会,输水系统的维护和水资源分配条例的实施工作得到改善。可是,它们对控制盐渍化的贡献很小,需要国家对其加以调控。
