本文研究了降低投入品關(guān)稅措施對(duì)企業(yè)投入品進(jìn)口、投入品質(zhì)量,以及企業(yè)生產(chǎn)率的影響。此外,還研究了降低投入品關(guān)稅對(duì)企業(yè)產(chǎn)品范圍和就業(yè)的影響。本文共分七章。第一章介紹了研究動(dòng)機(jī),提出了研究問題,介紹數(shù)據(jù)來源。本文旨在回答以下問題:降低投入品關(guān)稅有助于企業(yè)的進(jìn)口強(qiáng)度和輸入質(zhì)量的提升,并進(jìn)一步提高企業(yè)的生產(chǎn)率嗎?降低投入品關(guān)稅會(huì)影響企業(yè)的產(chǎn)品范圍和就業(yè)嗎?基于埃塞俄比亞統(tǒng)計(jì)局在1996年至2016年期間收集的埃塞俄比亞制造業(yè)普查的面板數(shù)據(jù),并使用來自世界綜合貿(mào)易解決方案(WITS)的相應(yīng)關(guān)稅數(shù)據(jù)進(jìn)行匹配來回答以上問題。第二章梳理了相關(guān)的文獻(xiàn)。第三章闡述了理論機(jī)制。第四章根據(jù)研究對(duì)象的經(jīng)濟(jì)貿(mào)易改革的發(fā)展情況,對(duì)制造部門和對(duì)外部門進(jìn)行了基本分析。第五章概述了經(jīng)驗(yàn)?zāi)Ｐ�、估�?jì)方法和估計(jì)步驟。第六章對(duì)數(shù)據(jù)進(jìn)行描述性分析,并對(duì)實(shí)證結(jié)果進(jìn)行分析。實(shí)證分析分為兩個(gè)部分。第一部分首先測(cè)度投入品關(guān)稅降低對(duì)企業(yè)進(jìn)口強(qiáng)度的影響,然后進(jìn)一步分析投入品關(guān)稅降低對(duì)企業(yè)投入質(zhì)量提升和生產(chǎn)率的影響�？梢垣@得足夠詳細(xì)的數(shù)據(jù)進(jìn)行實(shí)證研究。本文使用Levinsohn和Petrin(2003)的方法估計(jì)微觀層面的生產(chǎn)率,該方法可以控制聯(lián)...
