中国制造业转型升级与新微笑曲线理论

鉴于中国制造业转型升级支持理论的不足，将科技水平变量引入传统微笑曲线模型，发现传统微笑曲线理论和倒微笑曲线理论仅描述了产业链附加值分布图的一部分，只有两者结合才能构成完整的微笑曲线理论，即新微笑曲线理论。此外，基于新微笑曲线理论，提出对中国制造业转型升级的3个重要启示：①无论选择哪一条转型升级路径，加大科技投入、进行科技创新及提升科技水平均是中国制造业实现转型升级的根本路径；②价值链高端和低端的划分实际上是一个动态变化的概念，只要加大生产制造环节的科技投入，积极进行科技创新，大幅提升其科技水平，在一定条件下，产业链生产制造环节也能处于价值链高端；③对于当前大多数中国制造企业而言，其转型升级路径是直接在生产制造环节进行转型升级而非沿着产业链向两端攀升。

Chinese Manufacturing Industry Transformation and Upgrading and the New Smiling Curve Theory

Aiming at the shortage of Chinese manufacturing industry transformation and upgrading theory, the paper introduces one new variable, scientific and technical level, into traditional smiling curve model. It is found that traditional smiling curve theory and inverse smiling curve theory only describes half of the industrial chain added value cure，only the combination them together constitute the complete smiling curve theory, namely new smiling curve theory. Based on the new theory，the paper puts forward three new viewpoint about Chinese manufacturing industry transformation and upgrading:① increasing investment in science and technology, doing scientific and technological innovation, enhancing scientific and technical level is the fundamental path of Chinese manufacturing industry transformation and upgrading regardless of which one to choose the path of transformation and upgrading.②The division of the value chain's the high-end and low-end actually is a dynamic, changing concept, as long as the increasing the manufacturing sector investment in science and technology, actively carrying out scientific and technological innovation, significantly enhance the level of science and technology to a certain degree, the manufacturing sectors can also become high-end of the value chain.③For the majority of Chinese manufacturing enterprises, its most suitable path of transformation and upgrading is directly in the production and manufacturing sectors to upgrade rather than rising along both ends of industrial chain.
