生产率衡量的是将投入转变为产出的效率，决定着一个企业、一个地区乃至一个国家的长期竞争力，贸易开放对生产率的影响是经济学研究的核心课题之一。在新的国际形势下，扩大贸易开放、提高生产效率、促进经济长期增长，对于发展中国家特别是处于改革关键时期的中国具有十分重要的意义。

本书在系统梳理生产率与贸易开放理论发展的基础上，采用规范研究与实证研究相结合、模拟分析与回归分析相结合的方法，从关税壁垒、非关税壁垒、进口渗透以及企业贸易行为的角度，基于国家、行业和企业三个层面，使用宏观数据、产业数据和微观数据，深入分析了发展中国家贸易开放对于生产率的影响。

Productivity measures the efficiency of transforming inputs into outputs, determines the long-term competitiveness of a firm, a region, and even a country, and the impact of trade openness on productivity is one of the core topics of economic research. Under the new international situation, expanding trade opening-up, improving production efficiency and promoting long-term economic growth are of great significance to developing countries, especially China, which is in a critical period of reform. On the basis of systematically combing the development of productivity and trade opening theory, this book adopts the method of combining normative research and empirical research, simulation analysis and regression analysis, and uses macro data, industrial data and micro data to deeply analyze the impact of trade opening of developing countries on productivity from the perspectives of tariff barriers, non-tariff barriers, import penetration and enterprise trade behavior.（AI翻译）
