日前欣闻本刊“多元化经营”栏目的主持人康荣平、柯银斌写出了一部新著———《企业多元化经营》 ,而且 ,由此还引出了一件新鲜事 :海尔集团总裁张瑞敏为该书写了个序言。因为通常 ,为他人著作写序 ,是知名学者或政界名流的事。作为一个企业家特别是世界知名的企业家为一部书作序 ,确实并不多见。这确不多见的新鲜事或许说明了两个问题 :一是中国的经济理论需要企业实践者特别是企业家的注释 ,二是中国的企业家需要符合实践轨迹的经济理论。在本期的《多元化经营》栏目中 ,我们把张瑞敏总裁所作的序言奉献给读者 ,希望读者能够从中获得新的启迪 A few days ago I was glad to hear that Kang Rongping and Ke Yinbin, the moderators of our magazine Diversified Business, wrote a new book, “Diversification of Business,” and led to one more thing: Zhang Ruimin, president of Haier Group Wrote a preamble for the book. Because, usually, writing an essay for another book is a well-known scholar or politician. Preface to a book as an entrepreneur, especially a world-renowned entrepreneur, is indeed rare. This rare new incident may explain two problems: First, China's economic theory requires the comment of business practitioners, especially entrepreneurs; second, Chinese entrepreneurs need economic theory that is in line with the practice. In this issue of “Diversification”, we dedicate the preface made by President Zhang Ruimin to readers and hope readers can get new inspiration from it
