中国农业补贴政策及其实施效果分析

近几年,中央根据粮食产销形势的新变化,先后出台了良种补贴、粮食直补、农机具购置补贴等一系列农业补贴政策,初步形成了农业补贴政策框架。这些措施极大地调动了广大农民种粮积极性,有力地推动了粮食生产的恢复发展,基本实现了粮食增产和农民增收的政策目标。但由于中国农业补贴政策体系仍处于初创阶段,在实施过程中仍存在许多问题。首先对中国农业补贴政策的实施现状进行了分析。然后,基于对江西省的实地调查数据,运用Cobb-Douglas生产函数对中国农业补贴效果进行了定量研究。最后,提出完善中国农业补贴政策的对策建议。研究的主要结论是,中国农业补贴政策在实施过程中仍存在许多问题,如补贴政策目标的短视化、补贴方式不科学、补贴结构不合理、补贴机制不健全等,应针对以上具体问题调整农业补贴政策的具体实施方式。     

Research on the Effectiveness of the Direct Regulation Pricing Methods of Public Utility

This paper analyzes the industrial organization of public utility and its cause and synthetically researches government direct regulating pricing methods of public utility, mostly the static or dynamic cost mark-up pricing methods. It is indicated by the means of game theory and imperfect contract theory, under the conditions of imperfect information and the government's inferior position, It's impossible to develop the incentive mechanism to utility enterprise, makes low productivity in public utility. The inefficiency of the cost monitor and control is inevitable when the direct regulation pricing system be used. The thought of direct pricing methods is a mechanical obstruction to improve the effectiveness of public utility. It's the radical approach for the government to reform the regulation modes in order to improve the effectiveness and social surplus of public utility.     

Influencing the global through understanding the local: Harold Brookfield's contribution to international organisations' biodiversity policy

Abstract: This article focuses on a significant paradigm shift in the approaches to biodiversity conservation in the developing countries that has affected important international organisations, including the Global Environment Facility (GEF). This paradigm shift marks a movement beyond protected areas to production landscapes. It is argued that one particular project, People, Land Management and Environmental Change (PLEC), developed under the leadership of Harold Brookfield has contributed significantly to the shift. The project was instrumental in introducing the term ‘agrodiversity’ that encompasses biological diversity as well as the management diversity found in smallholder agricultural systems at all levels. The article describes the evolution of PLEC into a major international collaborative project funded through the GEF. It highlights the project's main achievements and its influence on the policy‐making in the GEF relying on the findings of independent evaluations.

Maintaining estuary quality for shorebirds: towards simple guidelines

It is increasingly important to be able to monitor and maintain the quality of estuaries for overwintering shorebirds. Bird numbers alone are not sufficient to indicate quality nor, as recent research shows, can it be assumed that site quality is being maintained simply because there is enough food to meet the birds’ physiological demands; i.e., the amount of food available per bird in autumn needs to be greater than the amount eaten. But how much greater? We used a simple individuals-based and behaviour-based model to explore the factors that affect the relationship between overwinter mortality and the amount of food available per bird in autumn (the food:bird ratio). The aims were to explore how the natural history characteristics of a shorebird species affected the shape of this relationship, in order to identify characteristics of the system that should be included in any monitoring programme of site quality. In all cases there was a minimum threshold food:bird ratio above which mortality did not vary and below which mortality increased steadily. The amount of food per bird required at the threshold varied from one to six times the amount actually consumed by each bird during winter, depending on the amount of realism included in the model. The minimum threshold ratio was most strongly influenced by the shape of the relationship between intake rate and prey density - the functional response - and, when interference competition occurred, by the distribution of the birds’ main food supply. Simulations with realistic spatial distributions of prey predicted that the minimum required amount of food per bird would be between two and five times the amount actually consumed. The threshold approach could provide a simple method of monitoring estuary quality based on food supply and bird numbers. It also provides a potentially clearly-defined and unambiguous measure of the carrying capacity of a site. If applied to a sufficient number of real estuaries, general guidelines for maintaining estuary quality based on estuary characteristics, food supply and bird species might be established.     

Reinventing rural development in Vietnam: Discursive constructions of grassroots democracy during the renovation reform

Over the past decades Vietnam has seen striking efforts to reinvent the exercise of democratic rural development. Promotion of grassroots democracy, notably under the Grassroots Democracy Decree (GDD), has been an acute response by Communist Party and government to large scale unrest among the rural populace owing to dissatisfactions with a felt mismatch between espoused commitments to ‘good governance’ and its actual practice. Through evidence from field work, this paper assesses the implications of the GDD in the central and northern highlands, analyzing how the promotion of grassroots democracy is discursively constructed by rural development professionals. The results outline three dominant discourses, which center on their respective interests in liberalist democratization, improved efficiency in state renovation, and enhanced accountability in governing local policy ambiguities. It argues that ‘grassroots democracy’ is serving as a conceptual mediator, supporting learning between diverging interests associated with rural development and different ideological positions shrouding the notion of democracy itself. Yet, given the extent that discourses are reflective of how professionals relate to grassroots aspirations, grassroots movements, which originally ushered the Party and central government to pass the GDD, have a significant struggle ahead of them to affect concrete changes in professionals' practices.

海峡两岸农地利用政策的比较研究

农地利用政策的目的主要在于合理利用农地资源、提升农地利用效率。该文对大陆与台湾农地利用政策异同点进行梳理,认为两岸在政策制定的最初目标、发展核心、近年关注焦点等方面较为类似,而在农地权益演变、制度变迁方式、政策侧重点等方面存在差异,并就大陆农地政策发展趋势提出农地利用政策变革应逐步趋向"上下互动"方式,要"以提高农地利用效率"为目标,农地利用要趋向组织化、规模化及要加强农地分级利用管理等建议。
