【摘要】：中國的改革開放取得了巨大的成就,出口已經(jīng)成為帶動中國經(jīng)濟(jì)發(fā)展的引擎之一。在出口的過程中,我國涌現(xiàn)出了一大批具有先進(jìn)技術(shù)的產(chǎn)業(yè)和企業(yè),但是也有一些企業(yè)的經(jīng)營受到國際市場波動的影響。當(dāng)前國內(nèi)外學(xué)者在異質(zhì)性企業(yè)貿(mào)易理論的影響下,采用不同的數(shù)據(jù)和及計量方法去研究出口過程中的自選擇效應(yīng)和出口學(xué)習(xí)效應(yīng),得出的結(jié)論也各不相同。本文則從生產(chǎn)率分布的分位點(diǎn)角度去研究出口與生產(chǎn)率的問題,并試圖修正之前理論和實(shí)證研究中的一些紕漏。文章首先把出口學(xué)習(xí)效應(yīng)納入到異質(zhì)性企業(yè)貿(mào)易理論的分析框架下,把自選擇效應(yīng)和出口學(xué)習(xí)效應(yīng)融合到一個理論模型中,同時指出自選擇效應(yīng)主要作用于生產(chǎn)率的低分位點(diǎn),會使其分布產(chǎn)生左斷尾現(xiàn)象,而出口學(xué)習(xí)效應(yīng)則使得生產(chǎn)率分布整體向右移動,并給出了兩種效應(yīng)對生產(chǎn)率影響的圖形表示。接下來本文使用傾向得分匹配的方法,克服樣本選擇偏誤和內(nèi)生性問題,測度出樣本考察期間出口行為可以提升0.231個單位的生產(chǎn)率,分年份結(jié)果則顯示這種促進(jìn)作用會隨著年份的增加而減少,甚至在后期產(chǎn)生負(fù)面影響。隨后的圖形識別法顯示出口企業(yè)生產(chǎn)率分布有左斷尾現(xiàn)象,從而證實(shí)了自選擇效應(yīng)的存在；而其生產(chǎn)率分布在后期沒有右移動的現(xiàn)象,從而說明出口學(xué)習(xí)效應(yīng)在考察后期并不存在,此外文章通過比較生產(chǎn)率高低分位點(diǎn)的數(shù)值亦得出同樣的結(jié)論。接下來文章進(jìn)行了分位數(shù)回歸以及穩(wěn)健性檢驗,控制其他因素之后,依然得出了自選擇效應(yīng)存在,而出口學(xué)習(xí)效應(yīng)不存在的結(jié)論。文章還對出口學(xué)習(xí)效應(yīng)不存在的原因進(jìn)行了分析,加工貿(mào)易和勞動密集型企業(yè)的存在導(dǎo)致了這種現(xiàn)象。最后文章就實(shí)證結(jié)果提出了一些政策上的建議。
[Abstract]:China's reform and opening up has made great achievements, export has become one of the engines of China's economic development. In the process of export, a large number of industries and enterprises with advanced technology have emerged in our country, but there are also some enterprises whose operation is affected by the fluctuation of international market. At present, under the influence of heterogeneous enterprise trade theory, scholars at home and abroad adopt different data and measurement methods to study the self-selection effect and export learning effect in the process of export, and the conclusions are different. In this paper, the problem of export and productivity is studied from the point of view of productivity distribution, and some flaws in previous theoretical and empirical studies are tried to be corrected. In this paper, the export learning effect is first incorporated into the analysis framework of heterogeneous firm trade theory, and the self-selection effect and export learning effect are integrated into a theoretical model. At the same time, it is pointed out that the self-selection effect mainly acts on the low-score sites of productivity. The distribution will cause the phenomenon of left tail break, while the export learning effect will make the productivity distribution move to the right as a whole, and the graphic representation of the two effects on productivity is given. Then we use the tendency score matching method to overcome the sample selection bias and endogenous problems, and measure that the export behavior can increase the productivity of 0.231 units during the sample investigation. The year-by-year results showed that the promotion would decrease with the increase of years, or even have a negative effect in the later stage. Subsequently, the graph recognition method shows that the productivity distribution of export enterprises has left tail break phenomenon, which confirms the existence of self-selection effect, and its productivity distribution does not move to the right in the later period. It is shown that the export learning effect does not exist in the later period of investigation, and the same conclusion is obtained by comparing the values of high and low productivity loci. After controlling for other factors, the conclusion is that the self-selection effect exists, but the export learning effect does not exist. The paper also analyzes the reasons why the export learning effect does not exist, which is caused by the existence of processing trade and labor-intensive enterprises. Finally, the paper puts forward some policy suggestions on the empirical results.
