经济学的度量空间与度量对象

The Metric Space and Measurement Object for Economics

经济学数量模型的应用效果普遍不是很好,一个重要原因是不能满足数学模型对完备度量空间的要求。而度量空间不完备的主要原因则是度量对象不够准确。经济学正确的度量对象是产权。相应地,经济学的研究对象应该是产权关系,也就是马克思主义经济学所称的所有制关系。产权在交换时表现出价值。由于产权的载体通常是产品,人们一直将产权的市场价值误称为产品的市场价值。这种误解应当纠正过来。以产权作为经济学的基本量纲,才能构建比较完备的度量空间。有了比较完备的度量空间,经济学模型才能实现“理论与事实之间的必要互动”。

The economic quantitative models are generally not very effective for practical application. One of essential explanations is that the models do not meet the requirement of mathematical models for complete metric space. The main cause of incomplete metric space is that the measurement object for economics is not well defined. The correct measurement object for economics is the property right. Therefore,the research object of economics should be the property right relation,that is the ownership relation called by Marxist economics. Property right show its value through exchange. People have always mistakenly referred to the market value of property rights as the market value of products because property rights are usually embodied in products. This error should be corrected. Only by taking property right as the basic dimension of economics can a relatively complete metric space be constructed. With a relatively complete metric space,the economic model can realize the necessary interaction between theory and matter-of-factness.
