【摘要】：随着国际分工垂直专业化程度的加深,中间品贸易已成为我国乃至全球化生产中的重要环节,国内外许多学者对此做了相关研究,其中的热点集中在进口中间品对生产率影响的探究上。但至今学界对此并无一致结论,这就对我们从微观角度更为精确的研究进口中间品对生产率的影响提出了要求。近些年,以Alexis Antoniades(2015)为代表的一些文献陆续提出了产品质量内生化模型,将原本视为外生的产品质量,纳入到企业利润最大化行为中。产品异质性理论和质量内生化模型的提出为我们提供了一个新的视角去观察进口中间品对企业生产率的影响。鉴于国内外有关这方面的研究还非常不足,本文便以进口中间品质量为切入点研究对企业全要素生产率的影响。在异质性企业理论的基础上,本文借鉴Amit KKhandelwal(2013)的方法,借助中国海关数据库的数据测算了中国企业2000-2006七年的进口中间品质量;借助中国工业企业数据库的数据,用半参数LP法测算企业全要素生产率。在Alexis Antoniades(2015)模型的基础上提出假设并构建计量模型,然后用面板的固定效应进行估计,从整体和分组两个层次验证了进口中间品质量对企业全要素生产率的促进关系。通过实证分析,我们得到如下结论:(1)我国进口中间品质量整体上呈现逐年递增的趋势,其中从事一般贸易的企业和从事加工贸易的相差不多,但从发达国家进口的中间品质量要明显高于从发展中国家进口的,中高技术行业也明显高于中低技术行业。从企业所有制的不同类型看,外资企业的进口中间品质量最高,国有企业次之,私营企业最低;(2)整体上看,进口中间品质量的提高对企业全要素生产率有显著的促进效应,这一结果在考虑了内生性问题后依然稳健;(3)通过对分组回归结果中进口中间品质量估计系数的横向对比,我们发现从事加工贸易的企业、外资企业和从发展中国家进口的企业以及中高技术行业的企业的进口中间品质量对企业全要素生产率会有更强的正向影响,这一结果同样通过了稳健性检验。最后,本文根据实证结果提出了政策建议。
[Abstract]:With the deepening of international division of labor and vertical specialization, intermediate trade has become an important link in our country and even in the global production. Many scholars at home and abroad have done relevant research on it. The focus is on the impact of imported intermediates on productivity. However, there is no consistent conclusion, which requires us to study the impact of import intermediates on productivity more accurately from a micro perspective. In recent years, some literatures, such as Alexis Antoniades 2015, have put forward the endogenous biochemical model of product quality, which is originally regarded as exogenous product quality, which is included in the profit maximization behavior of enterprises. The theory of product heterogeneity and the endogenous biochemistry model of quality provide us with a new perspective to observe the influence of imported intermediates on the productivity of enterprises. In view of the lack of domestic and international research on this aspect, this paper studies the impact of imported intermediate quality on the total factor productivity of enterprises. On the basis of heterogeneous enterprise theory, this paper uses the method of Amit KKhandelwaler (2013) to calculate the quality of import intermediates of Chinese enterprises in the seven years from 2000 to 2006, and the data of China's industrial enterprise database. The semi-parameter LP method is used to measure the total factor productivity of enterprises. On the basis of Alexis Antoniades 2015) model, the hypothesis is proposed and the econometric model is constructed. Then the fixed effect of panel is used to estimate the relationship between the quality of imported intermediate goods and the total factor productivity of enterprises. Through empirical analysis, we get the following conclusion: (1) the quality of China's import intermediates is increasing year by year, and the difference between enterprises engaged in general trade and processing trade is not much. However, the quality of intermediate products imported from developed countries is obviously higher than that from developing countries. In terms of different types of enterprise ownership, foreign-funded enterprises have the highest quality of imported intermediates, state-owned enterprises take second place, and private enterprises have the lowest quality.) on the whole, the improvement of the quality of imported intermediates has a significant promoting effect on the total factor productivity of enterprises. After considering the endogenous problem, this result is still robust. (3) by comparing the estimation coefficient of import intermediate quality in the result of grouping regression, we find that the enterprises engaged in processing trade are engaged in processing trade. The quality of imported intermediates of foreign-funded enterprises, enterprises imported from developing countries and enterprises in medium and high technology industries will have a stronger positive impact on the total factor productivity of enterprises. This result has also passed the robustness test. Finally, according to the empirical results, this paper puts forward policy recommendations.
