制造业非均衡型技术蛙跳促进了中国经济的快速发展，也提高了制成品的技术含量，但其使得中国的技术创新能力与经济发展水平逐渐偏离，出现外部过度依赖型技术升级和经济增长，使得中国经济易受外部冲击，为长期健康、可持续发展埋下隐患。因而非均衡型技术蛙跳在一定程度上有悖于"稳中求进，促进经济健康发展"的要求，为此，本课题基于产品技术含量来源视角，在识别制造业非均衡技术蛙跳类型的基础上，建立非均衡型技术蛙跳机制与效应的理论，进而借助实证手段揭示不同地区和要素密集型制造业非均衡型技术蛙跳的内在机制与外在效应，并预测上述机制与效应的未来趋势，最后构建相应的优化思路和政策体系。本课题以十八大后中央经济政策取向为依据，深入分析中国非均衡型技术蛙跳的机制与效应，所得结论既能为中国解决关键技术和部件外部依赖问题提供新思路，也能为中国制定经济发展方式转变方面的政策提供理论依据，还能为未来经济政策的取向提供参考。

Unbalanced leapfrog of technology in manufacturing industry promoted the growth rate of China, it also improves the technological content of Chinese products. But it induces the departure of the innovation ability and economic growth, which makes the growth and technology progress of China highly depend on foreign countries. Such conditions not only violate the request of central government's economic policy, but also will harm the economic growth in long run. In order to better the conditions above, we study the unbalanced leapfrog from the angle of technology included in the products, the research contents are arranged as following: (1) Identify the kinds of unbalanced leapfrog of technology of manufacturing industry.(2) Construct the theory to explain the mechanisms and effects of unbalanced leapfrog, and study the Chinese characteristics through some estimation model, then forecast the trend of Chinese characteristics.(3)Base on the factors of China and the conclusion above ,this project put forward the some routines and policies to better the leapfrog of Chinese manufacturing. This project base on the policies of central government which are put forward after the eighteenth National Congress of the CPC, analysis the mechanisms and effects of unbalanced leapfrog in China, the results will provide ideas to solve the problem of key technology and accessory dependence, moreover they will be useful to the policy-making of China.
