【摘要】：隨著國際分工垂直專業(yè)化程度的加深,中間品貿(mào)易已成為我國乃至全球化生產(chǎn)中的重要環(huán)節(jié),國內(nèi)外許多學者對此做了相關(guān)研究,其中的熱點集中在進口中間品對生產(chǎn)率影響的探究上。但至今學界對此并無一致結(jié)論,這就對我們從微觀角度更為精確的研究進口中間品對生產(chǎn)率的影響提出了要求。近些年,以Alexis Antoniades(2015)為代表的一些文獻陸續(xù)提出了產(chǎn)品質(zhì)量內(nèi)生化模型,將原本視為外生的產(chǎn)品質(zhì)量,納入到企業(yè)利潤最大化行為中。產(chǎn)品異質(zhì)性理論和質(zhì)量內(nèi)生化模型的提出為我們提供了一個新的視角去觀察進口中間品對企業(yè)生產(chǎn)率的影響。鑒于國內(nèi)外有關(guān)這方面的研究還非常不足,本文便以進口中間品質(zhì)量為切入點研究對企業(yè)全要素生產(chǎn)率的影響。在異質(zhì)性企業(yè)理論的基礎(chǔ)上,本文借鑒Amit KKhandelwal(2013)的方法,借助中國海關(guān)數(shù)據(jù)庫的數(shù)據(jù)測算了中國企業(yè)2000-2006七年的進口中間品質(zhì)量;借助中國工業(yè)企業(yè)數(shù)據(jù)庫的數(shù)據(jù),用半?yún)?shù)LP法測算企業(yè)全要素生產(chǎn)率。在Alexis Antoniades(2015)模型的基礎(chǔ)上提出假設(shè)并構(gòu)建計量模型,然后用面板的固定效應進行估計,從整體和分組兩個層次驗證了進口中間品質(zhì)量對企業(yè)全要素生產(chǎn)率的促進關(guān)系。通過實證分析,我們得到如下結(jié)論:(1)我國進口中間品質(zhì)量整體上呈現(xiàn)逐年遞增的趨勢,其中從事一般貿(mào)易的企業(yè)和從事加工貿(mào)易的相差不多,但從發(fā)達國家進口的中間品質(zhì)量要明顯高于從發(fā)展中國家進口的,中高技術(shù)行業(yè)也明顯高于中低技術(shù)行業(yè)。從企業(yè)所有制的不同類型看,外資企業(yè)的進口中間品質(zhì)量最高,國有企業(yè)次之,私營企業(yè)最低;(2)整體上看,進口中間品質(zhì)量的提高對企業(yè)全要素生產(chǎn)率有顯著的促進效應,這一結(jié)果在考慮了內(nèi)生性問題后依然穩(wěn)健;(3)通過對分組回歸結(jié)果中進口中間品質(zhì)量估計系數(shù)的橫向?qū)Ρ?我們發(fā)現(xiàn)從事加工貿(mào)易的企業(yè)、外資企業(yè)和從發(fā)展中國家進口的企業(yè)以及中高技術(shù)行業(yè)的企業(yè)的進口中間品質(zhì)量對企業(yè)全要素生產(chǎn)率會有更強的正向影響,這一結(jié)果同樣通過了穩(wěn)健性檢驗。最后,本文根據(jù)實證結(jié)果提出了政策建議。
[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.
