| Technological leapfrogging is the most important way for China to catch up developed countries. But there are few deep-seated theories of technological leapfrogging in China at the present time, and have not come into being a uniform theory. Furthermore, existing related theories are not got a success in explaining and guiding technical progress, economic grow and catching-up developed countries for China. Under this circumstances, researching the theories of technological leapfrogging and directing Chinese enterprise is very important.The paper outspreaded from the theoretics and the practice, the theoretics the former, the practice the latter; the theories of technological leapfrogging the former and the Chinese practice the latter, amalgamated the two of them.The paper answered why technological leapfrogging will be in the first. So, the author analyzed the base of technological leapfrogging and cleared up the theories involving catching-up and leapfrogging. The author reconstructed some theories of technological leapfrogging such as the definition, the essence, the characteristics, the impetuses, the system, the inward-foundations and so on in the paper. On the base of these, the author put forward the different patterns of technological leapfrogging and the characteristics, the conditions of each of them in the part of theory research.The intent of the paper is study the theories of technological leapfrogging and construct the theoretic system of it so as to steer China to catching-up. So, Chinese practice of technological leapfrogging is the paper's practicing part one. From the angle of modernization, the author analyzed why not success for China in the past tough it also has implemented catching-up stratagem such as "learning from outlander" of Wei-Yuan, Yang-Wu movement, "learning from Occident" of Sun Zhong-shan, the big jump, the foreign jump and the references produced from them for our technological leapfrogging. Then, the author analyzed the conditions that China possessed and not possessed. On the base it, the author put forward the different patterns of technological leapfrogging of China and several advices according with the situation of China. |
