In recent years, great progress in CM research has been achieved with the initiation of application of sustained and multifaceted use of modern scientific methods. More and more innovative methods are widely used in CM modernization researches, and the application of new methods becomes the key to further develop CM modernization.展开更多

The author shows why some reasons, according to which we should use mathematics in (economic) theory, are not convincing (they are even tautological), and what does mathematization have to do with arbitrariness of the orthodox economic theory. The author also shows why using game theory (a mathematical discipline) in modem microeconomics does not yield knowledge and correct explanation of economic situations and phenomena. At the end, the author presents fundamental questions that form the basis of economic science and its qualitative research methods, and shows what their practical relevance is. The purpose of this article is to argue, contrary to common opinion, that there can be an exact and objective science of economic phenomena that does not necessarily use modem mathematical theories or methods to explain these phenomena.展开更多
