中文摘要：

面对错综复杂而又不断演进的经济世界，充满理性的实证主义者以选择性假设作为实证研究的逻辑起点的做法，为实证分析的范围和效果预设了局限性，体现为理论研究的狭隘性、碎片化和逻辑谬误三个方面的缺陷；作为分析工具的数理分析与经验检验未能解决这些问题，只是放大了问题的严重性。这种“实证”方法缺失了客观公正的求实精神与价值诉求。实证主义应以客观公正的价值取向与追求真理的精神，不惟形式化与经验至上，方能建构适应实践真正所需的方法与理论体系。

英文摘要：

Facing the complicated and developing economic world, rational positivists take se- lective hypothesis as the logical starting point of empirical studies, which brings limitations to the scope and effect of empirical researches, characterized by the/imitation, fragmentation and logical fallacies in theoretical researches. As analytical tools, mathematical analysis and empirical test cannot solve the problems, but to make them be more serious. The ＂empirical＂ method lacks ob- jective and fair positivist spirit and value demand. Instead of advocating formalism and empiri- cism, positivism should also be based on the objective and fair value orientation and the spirit of pursuing truth to form the methods and theoretical system of practice.
