摘要
按照“瓦格纳法则”的解释 ,在市场经济条件下 ,公共支出的相对规模存在不断上升趋势。为此西方的很多经济学家从多方入手 ,找出了一系列的推动因素来论证该法则的合理性。但是公共支出的规模毕竟要受公共需求、政府的行政规模和工作方式以及政府收入能力的影响 ,在个体理性和技术进步的影响下 ,社会公众会越来越倾向于采用市场交换的方式而不是政府提供的方式来获取所需的产品与服务 ;政府的行政规模会越来越小 ,由市场来提供原本由政府提供的产品与服务逐渐成为可能 ;社会公众会把越来越小的财富份额转移给政府。这就使得公共支出的相对规模不会一直增长下去 ,它必会存在一个合适的极值 ,甚至会在此极值后呈现出逐渐下降的态势。
According to “Wagner Principle”,the relative proportion of public expenditure to GDP rises continuously. Lots of economists have discovered too many factors to illustrate it and to prove that “Wagner Principle” is a truth. The relative proportion of public expenditure to GDP is always restrained by there variables, those are, the public demands, administrative scale and methods, and government's capacity of revenue. With the influences of individual rationality and of the improvement of technology, the public definitely prefer obtain what they need from market instead if government; the administrative scale becomes smaller; market can support more and more what were once provided by government; the public prefer to transfer smaller and smaller part of their wealth to the government. So the relative proportion of public expenditure to GDP will not rise continuously in the market-directed economy, it has a biggest number, and will even descend after the extremum.
