本文通过VAR模型与Granger因果检验分析贸易结构和人力资本联合指标对全要素生产率的影响。结果显示:相对于中低技术品,高技术品进口的技术溢出效果更明显;相对于人力资本分布,人力资本水平对技术溢出的吸收效果影响更大。因此,若要提高全要素生产率,应调整贸易结构和增加教育投资。 In this paper, the VAR model and Granger causality test are used to analyze the impact of the combined indicators of trade structure and human capital on total factor productivity. The results show that compared with medium and low-tech goods, the technology spillover effect of high-tech goods is more obvious. Compared with the distribution of human capital, the level of human capital has a greater impact on the absorption effect of technology spillover. Therefore, to improve TFP, we should adjust the trade structure and increase investment in education.
