摘要
近年来,我国依靠加工贸易模式参与全球价值链分工体系的程度日益深化,中国企业的中间品进口行为不断增加。为考察近年来进口中间品的成效,文章选取2000-2006年中国工业企业数据库与海关贸易统计库合并数据,基于不同出口强度企业视角,使用普通最小二乘(OLS)、广义矩估计(GMM)等方法对企业中间品进口对其全要素生产率的影响进行考察,并采用倾向评分匹配法(PSM)和倍差法(DID)进行稳健性检验。多种检验结果表明:内销企业和出口企业进口中间品对全要素生产率均具有促进作用,且该效应在内销企业较为显著;将出口企业细分为一般出口企业和纯出口企业,发现进口中间品对全要素生产率的促进作用依内销企业、一般出口企业和纯出口企业递减。其中出口企业中加工贸易类型企业占比较大是导致上述结论产生的主要原因;进一步地,异质性检验结果显示,进口中间品对技术吸收能力强、从发达国家进口以及外资企业的生产率促进效应更明显。文章为客观评估中国企业进口中间品成效提供了新视角,同时也为现阶段"促进口"战略调整及未来"促进口"战略实施提供了有益的政策启示。
In recent years, depending on processing trade modes, China＇ s participation in division system of global value chains deepens increasingly, and Chinese enterprises＇ behaviors of importing intermediate goods are gradually increasing. In order to study the effect of imported intermediate goods,based on the merged data of Chinese industrial enterprises and customs statistics from 2000 to 2006 and from the perspectives of different export intensities, this paper uses OLS and GMM to investigate the effects of the import of intermediate goods on total factor productivity of the enterprises. Then it employs propensity score matching and difference-indifference methods to make a robustness test. The results show that the import of intermediate goods in domestic enterprises and export enterprises has a positive effect on total factor productivity, and the effect is more significant in the domestic enterprises. When the export enterprises are divided into generally export enterprises and purely export enterprises, the promotion role of the import of intermediate goods in total factor productivity is diminishing by the orders of domestic enterprises, generally export enterprises and purely export enterprises. Greater proportion of processing trade enterprises in export enterprises is the main reason for the conclusions above. Furthermore, the results of heterogeneity test show that the effect of imported intermediate goods on total factor productivity is even obvious when enterprises own strong technical absorptive capacity and import from developed countries, or the enterprises themselves are foreign-funded. It not only provides a new perspective for the objective evaluation of the effectiveness of Chinese enterprises in the import of intermediate goods, but also offers useful policy enlightenment for governments＇ current ＂promoting the import＂ strategy adjustment and future ＂promoting the import＂ strategy implementation.
