改革开放以来，中国的史学研究取得了前所未有的成就，研究的规模和成果的数量都是空前的。但如果仔细审视这种发展现状，不免有“只见树木，不见森林”之虞，原因在于史学的研究质量还有改进的余地。因此，在知识经济时代，史学若想与时代同步，必须改变研究现状，在提高自己的研究质量上下功夫，以学术研究质量的最优化来获得社会效益的最大化。 Since the reform and opening up, historiography in China has made unprecedented achievements, the scale of the research and the quantity of the achievements are unprecedented. However, if we look closely at the current situation of development, we can not help but think that “we can only see trees and see no forest.” The reason lies in the fact that there is still room for improvement in the quality of historiography research. Therefore, in the era of knowledge-based economy, if history should keep pace with the times, it is necessary to change the status quo of research and make great efforts to improve the quality of its own research and to maximize the social benefits with the optimization of academic research.
