细分贸易对中国行业技术进步的影响

The Impact of Decomposed Trade on Technological Progress In China's Industries

基于中国1995—2009年的数据,建立动态面板模型探索不同贸易类型对行业技术进步的影响差异。研究发现:贸易的开展对中国技术进步的影响并非完全一致,不仅存在贸易种类间的差异,同时也存在行业间的差异。其中,对于制造业的技术进步来说,中间品出口、用于出口的中间品进口和用于国内生产的中间品进口这三类贸易存在促进效应,用于出口的中间品进口贸易的正向效应最高,最终消费品出口和进口贸易存在阻碍效应;对于服务业来说,最终消费品出口、进口和用于出口的中间品进口这三类贸易存在促进效应,用于出口的中间品进口贸易的正向效应最高,中间品出口和用于国内生产的中间品进口贸易存在阻碍效应。

By setting up dynamic panel models and adopting the data of Chinese industries from 1995 to 2009, this paper tries to explore the differences of influence that different types of trade have on the technological progress of industries. The result shows that the impact of trade on China＇ s technological progress is not entirely consistent, and there are differences among trade categories as well as among industries. For the technological advancement in the manufacturing industry, three types of trade, namely intermediate product exports, intermediate imports for export and intermediate imports for domestic production, have promoting effects and the positive effect of intermediate imports for export trade is the highest, whereas final consumer goods exports and import trade have deterring effect. For the service sector, three types of trade, namely final consumer goods exports, imports and imports of intermediates for export all have promoting effects and imports of intermediates for export trade has the highest positive effect while intermediate product exports and intermediate goods import trade for domestic production trade have deterring effect.
