【摘要】：公共物品研究是公共经济学的经典主题之一。在公共物品理论中,如何确定公共物品的最优供给水平的问题受到了众多经济学家的关注。本文拟对公共物品最优供给的新古典理论加以深入分析,并对新古典模型中的假设条件进行修正,从而研究在存在腐败行为的情况下,公共物品的供给水平会发生怎样的变化。本文首先提出了研究的主题,概述了关于本文主题的理论进展及研究现状,并介绍了本文的研究视角;此后,本文通过构建一个数学模型,对存在腐败条件下的社会计划者行为进行了形式化、模型化的研究。本文的主要结论是:在新古典的理论框架下,公共物品的最优供给由萨缪尔森规则决定。当我们放松其假设条件,引入腐败因素后,公共物品的供给数量相对于萨缪尔森规则发生偏离,高于(或低于)最优水平。并且,随着腐败程度的加深,偏离的程度逐渐增大。本文结构作如下安排: 第一部分是本文第1章,其主要内容是对有关公共物品提供理论的进展及研究现状作一个总体的阐述,并且说明本文的写作研究目的及研究视角。第二部分共分为三章(第2章、第3章、第4章),这三章的主要内容是在新古典的理论框架下,通过构造经济学中广泛运用的社会福利函数,以及个人效用函数,对在不同假设条件下的社会计划者行为作一个形式化、模型化的研究,以期望对公共物品提供理论有一个更为清楚的认识,进而分析公共物品过度供给或供给不足的政治原因。其中第2章是基本模型的构造与求解,第3章是扩展模型的构造与求解,第4章是模型的进一步扩展,并对“非仁慈”的社会计划者的行为进行更深入地分析和探讨。第三部分是本文第5章,其主要内容是在以上研究的基础上,对我国公共物品提供机制提出适当的政策建议。
[Abstract]:The study of public goods is one of the classic themes of public economics. In the theory of public goods, how to determine the optimal supply level of public goods has been concerned by many economists. In this paper, the neoclassical theory of the optimal supply of public goods is deeply analyzed, and the hypothetical conditions in the neoclassical model are modified to study how the supply level of public goods will change in the presence of corruption. In this paper, we first put forward the research topic, summarized the theoretical progress and research status of this topic, and introduced the research perspective of this paper. Then, by constructing a mathematical model, The behavior of social planners under the condition of corruption is formalized and modeled. The main conclusion of this paper is that the optimal supply of public goods is determined by Samuelson's rule under the framework of neoclassical theory. When we relax the hypothesis and introduce the corruption factor, the quantity of public goods supply deviates from the Samuelson rule, which is above (or below) the optimal level. Moreover, with the deepening of corruption, the degree of deviation gradually increases. This paper is structured as follows: The first part is the first chapter of this paper, its main content is to make a general description of the development and research status of the public goods supply theory, and to explain the purpose and research perspective of this paper. The second part is divided into three chapters (Chapter 2, Chapter 3, Chapter 4). The main content of these three chapters is to construct social welfare function and individual utility function, which are widely used in economics under the framework of neoclassical theory. This paper makes a formalized and modelled study on the behavior of social planners under different hypothetical conditions in order to have a clearer understanding of the theory of public goods supply, and then to analyze the political reasons for the oversupply or insufficient supply of public goods. Chapter 2 is the construction and solution of the basic model, chapter 3 is the construction and solution of the extended model, chapter 4 is the further expansion of the model, and the behavior of the "non-benevolent" social planners is analyzed and discussed more deeply. The third part is the fifth chapter of this article, its main content is on the basis of the above research, put forward the appropriate policy recommendations to our country public goods supply mechanism.
