任何学术研究工作 ,都必须创新 ,也难在创新。就经济史研究而言 ,挖掘新史料、开拓新领域 ,固然是实现创新的重要途径。但如果运用新的理论方法、从新的视角对学术界已经积累了丰富研究成果的老问题做出新的阐释 ,从而在前人的基础上将研究不断推向深入 ,其创新的意义同样重大 Any academic research work must be innovative, it is difficult to innovate. As far as the study of economic history is concerned, excavating new historical materials and opening up new fields is, of course, an important way to achieve innovation. However, if we use the new theoretical methods to make a new explanation of the old problems in the academic circles that have accumulated rich research results from a new perspective, we will continue to push forward the research based on the predecessors. The significance of innovation is equally significant
