The Effects Research Of China's Total Factor Productivity From Technology Spillover By Import

Technological progress is the key power for a country to maintain sustained economic development. For developing countries, they could through import trade, introducing the advanced technology from developed countries, in which they can enhance their skills with lower costs and faster speed ,and reduce the technology gap with developed countries. As a developing country, After the reform and opening up, especially after the establishment of socialist market economic system, china's import trade has experienced sustained growth. Meanwhile, technical products and manufactured goods imports are also expanding. At the same time, the efficiency of resource use and the level of technology achieved a sustained progress. Using the relevant data of China's market economy ,This paper want to analysis the existence of significant technology spillover from imports and its spillover effects on the contribution of technological progress.For the effective analysis of these problems, first of all the theory of the relationship between imports of domestic technology spillover and technological progress are reviewed. On this basis, using the comparative method, general analysis China's import trade and the technical features of trade goods. The empirical part of this paper is the core basis on these problem. First, based on CH model, combined with its expanding research get the static analysis model of this article. According to the model analysis needs, collecting data since 1993, and calculation the value of relevant variables of this model, and get the analysis data by type of model, and obtained conclusions through a complete analysis of the model. Subsequently,using impulse response and variance decomposition method to analyze the changes in imports,which influence the process of dynamic change of total factor productivity in China. With the above analysis, we obtain the following specific conclusions:(1)There is obvious technology spillover effects on China's imports, which is an important factor contributions to technological progress, and when our imports increased by 1%, can promote growth of 0.24% of China's technology progress.(2) In the dynamic analysis, the current increase in imports will have lasting positive impact on technological progress in China ,that there is a strong evidence on imported technology learning effect in our country, and advanced technology can be faster absorption and transformation. (3)There are the two main channels of Foreign R & D spillovers to our country, the import trade of the long-term contribution of technical progress effect is more obvious, and the positive spillover effects of FDI more concentrated in the short term, long-term dynamic effects are negative overall. Therefore, the expansion of imports is more conducive to long-term sustained improvement of TFP.
