投入品关税下降对企业投入质量、生产率和就业的影响

发布时间：2024-03-06 17:52

　　本文研究了降低投入品关税措施对企业投入品进口、投入品质量,以及企业生产率的影响。此外,还研究了降低投入品关税对企业产品范围和就业的影响。本文共分七章。第一章介绍了研究动机,提出了研究问题,介绍数据来源。本文旨在回答以下问题:降低投入品关税有助于企业的进口强度和输入质量的提升,并进一步提高企业的生产率吗?降低投入品关税会影响企业的产品范围和就业吗?基于埃塞俄比亚统计局在1996年至2016年期间收集的埃塞俄比亚制造业普查的面板数据,并使用来自世界综合贸易解决方案(WITS)的相应关税数据进行匹配来回答以上问题。第二章梳理了相关的文献。第三章阐述了理论机制。第四章根据研究对象的经济贸易改革的发展情况,对制造部门和对外部门进行了基本分析。第五章概述了经验模型、估计方法和估计步骤。第六章对数据进行描述性分析,并对实证结果进行分析。实证分析分为两个部分。第一部分首先测度投入品关税降低对企业进口强度的影响,然后进一步分析投入品关税降低对企业投入质量提升和生产率的影响。可以获得足够详细的数据进行实证研究。本文使用Levinsohn和Petrin(2003)的方法估计微观层面的生产率,该方法可以控制联...
