农村公共产品多元合作供给对供给绩效的影响研究

农村公共产品多元合作供给的效率一直不高,此种供给模式没有根本改善农村公共产品的供给绩效,改善农村公共产品多元合作供给绩效的首要问题就是探索多元合作供给对供给绩效的作用机理及其影响因素。因此,笔者将视角放在农村公共产品多元合作供给的过程上,通过分析合作关系的建立、稳定、发展及对供给绩效的影响,剖析农村公共产品多元合作供给对供给绩效的作用机理,从中探索可以改善合作供给效果、提高农村公共产品供给绩效的重要影响因素及维度,以期为农村公共产品供给实践提供理论参考。

Research on Supervision of Country Public Goods Supply Based on Public Choice Theory

To increase the provision of rural public goods is a major task of Chinese new rural construction, while it can not do without the necessary supervision. This paper described the relationship between public choice theory and the provision of rural public goods and it was a basis for in-depth study of the government＇s subject behavior from the perspective of public choice, and led to the necessity of regulation of rural public goods provision in rural areas, then it presented a strengthen monitoring of the rationalization proposals.     

农村公共产品质量的指标体系研究

农村公共产品是数量和质量的统一体。农村公共产品的供给理应考虑质量问题,这才算是一个完整的最优供给。农村公共产品质量代表了供给者的科技水平、生产水平、管理水平和文化水平。高质量的农村公共产品有利于满足消费者对公共产品的不断提高的质量需求,有利于树立供给者公众形象。有利于提高我国农业国际竞争力。因此,有必要探讨农村公共产品质量指标体系。

Towards multifunctional agriculture – weeds as ecological goods?

Agricultural land use has production, ecological, aesthetic and social functions. Certainly, in Europe, the concept of agricultural land use as being multifunctional seems to be increasingly accepted. Ecological goods and services can be rewarded as results or as actions – the differences between these ways are described and an outcome‐based rewarding system is elucidated for the creation of incentives for innovation and taking responsibility. The principle requirements for ecological goods are summarized. The contribution of agricultural land use to plant biodiversity is the most appropriated factor for an outcome‐based rewarding system. The various types of vegetation connected with agricultural land use can be used as recognizable ecological goods. The reasoning behind defining specific arable goods is shown. Information about creating the supply is available from the research performed on weed control in different arable systems. As the majority of ecological goods are public goods, mechanisms adapted from market situations for private goods must be stimulated and organized. The decision as to which ecological goods should be stimulated could be transferred to a decentralized and region‐specific public committee in which the relevant stakeholders are represented. Implementation exercises undertaken in a region of the German Federal State of Lower Saxony are introduced.
