问题的提出企业家现象普被许多经济学家所关注.从康替龙、萨伊到奈特和熊彼特,都发表过各自的见解,但不幸的是,在新古典经济学盛行的相当一段时间内,企业家理论在经济理论的发展中几乎消失了,这主要有两个方面的原因:一是新古典经济学关于信息可获得性的严格假设,其认为每个决策者都可以无成本地获得决策所需要的所有信息.这个假设使得决策过程变为机械地运用数学工具求解最大化的过程,而企业家那种充满想象和见识的决策就变得微不足道,企业家所承担的在不确定条件下决策的功能则在完全信息假设下消失殆尽;二是新古典厂商理论中生产函数和理性选择的逻辑排除了企业家的创新功能.生产函数已经为企业提供了一组投入和产出关系,决定了所有了解的产出和有效率的生产手段,故不需要企业家在组织和技术方面进行创新,来改变生产成本曲线和需求曲线.因此这两个假设都排斥企业家职能的存 Issues raised The phenomenon of entrepreneurship has been the focus of many economists, ranging from Comteon, Say, Knight, and Schumpeter to their own opinions, but, unfortunately, are prevalent in neoclassical economics For some time, the theory of entrepreneurs has almost disappeared in the development of economic theory. There are two main reasons for this. One is the strict assumption of neoclassical economics on the availability of information that every decision-maker can Costly access to all the information needed for a decision.The assumption makes the decision-making process into a mechanical use of mathematical tools to solve the process of maximization, and entrepreneurial kind of full of imagination and knowledge of the decision becomes insignificant, entrepreneurial commitment Second, the logic of production function and rational choice in neoclassical firm theory ruled out entrepreneur's innovative function.The production function has provided a set of inputs for the enterprise and Output relationship, determines all the output and efficient means of production know, it does not require entrepreneurs in the organization and technology innovation, to change the cost of production song Lines and demand curves, both of these assumptions exclude the functioning of entrepreneurship
