笔者采用中国工业企业数据库与海关数据库的匹配数据,结合回归分析与倾向得分匹配法验证资本品进口对中国企业全要素生产率的影响效应。研究结果表明:资本品进口对企业生产率具有显著的提升作用,但具体效果因企业类型而有所不同,对小型企业的提升效果好于大、中型企业,对中、高技术企业的提升效果好于中、低技术企业。扩大高技术资本品进口是改善企业生产率进而强化我国产品国际竞争力的重要手段,有利于贯彻我国“稳定出口、扩大进口、促进贸易平衡”的对外贸易发展战略。
The author uses the matching data of Chinese industrial enterprises database and customs database to verify the effect of capital goods imports on the total factor productivity of Chinese enterprises by combining regression analysis and propensity score matching method. The results show that the import of capital goods can significantly improve the productivity of enterprises, but the specific effects vary according to the types of enterprises, and the promotion effect on small enterprises is better than that of large and medium-sized enterprises and medium-and high-tech enterprises In the low-tech enterprises. The expansion of the import of high-tech capital goods is an important means to improve the productivity of enterprises and thus the international competitiveness of our products, and is conducive to implementing the foreign trade development strategy of “stabilizing exports, expanding imports and promoting trade balance.”
