Research Structure And Economic Growth Of China's Imports Of Tradable Goods

New Trade Theory tells us that besides static returns yields in trade,there are also dynamic returns and the later one are even more important.It comes from the technology spillover which decided by trade composition.It means, except through R&D,the main way for developed countries,developing countries can also utilize the technology spillover to raise their own technology level.By doing so will dramatically cut down the cost for development.Import is a key channel for the spillover.For an open economy,one can not only purchase hi-teach products but also advanced intermediate products to elevate the technical content embodied in productivity.Compared to export,import is a more direct way for technology spillover.Countries can share trade partners' R&D achievements through importation.This paper first establishes indexes to quantize our country's technology structure of import,and then analyzes the relation between these indexes and TFPG(growth of total factor productivity).In economic sense it also means the analysis whether technology spillover improve our country's economic development.This paper points out that a coordinated and balanced development between human capital and spillover through importation is of great importance.At the end of this paper,there are related measures to realize the lasting and sound economic development in the view of elevating import technical structure.
