20世纪80年代以来，非关税措施开始成为限制国际贸易的主要手段，涉及相当多的产品，且发展中国家和欠发达国家受到的影响最大。我国是世界上最大的发展中国家，也是贸易发展最迅速的国家之一，相比其他发展中国家，我国产品出口遭遇的非关税措施也更多、更复杂，特别是对我国吸引外商直接投资、引进先进技术有着重要意义的机电产品的出口。因此，研究非关税措施的作用机制及其效应原理，不仅可以有准备地应对国外实施的非关税措施，削减或消除各种壁垒的限制，还可以加强和完善我国贸易救济措施制度的建设，为我国机电产品贸易的发展，营造良好的外部和内部环境，具有十分重要的理论和现实意义。 目前，关于非关税措施对机电产品出口影响的效应研究及实证研究并不多，本文将此作为研究的重点。在掌握大量数据的基础上，通过比较分析国内外学者在非关税措施效应方面的研究成果，本文选用改良后的频度比例法对我国机电产品遭遇国外非关税措施的程度进行测量。并以此为基础，选取技术措施、绿色措施和专利措施作为主要的非关税措施，分别对其进行短期效应和长期效应的分析。除此之外，本文还打破常规，除了从出口国的角度，研究如何应对国外对我国机电产品出口设置的非关税措施之外，还从进口国的角度出发，分析了我国机电产业设置非关税措施的可能途径和具体构想，这也是本文的一个研究重点。 本文共分为五个部分，第一部分对本文的研究背景和国内外已有的研究方法进行了详细阐述；第二部分着重对非关税措施的内涵、分类进行界定，提出本文的研究基础。并在此基础上，对近年来，非关税措施呈现的特征和新发展趋势进行详细分析；第三部分，分析了我国机电产品出口的现状及其遭遇的主要非关税措施，对不同非关税措施进行涉案次数和金额比较，并通过实证分析对我国机电产品遭遇非关税措施的总体程度进行测量；第四部分，着重阐述了技术措施、绿色措施、专利措施等主要非关税措施对我国机电产品出口的影响；第五部分，在前文分析的基础上，提出了我国机电产品出口应对国外非关税措施的对策。并从我国实际出发，探讨如何结合自身的技术条件和优势，对机电产品进口设置合理的非关税措施，以保护我国国内机电产业的发展。

Since the 1980s, non-tariff measures have become the main measures that restrict international trade, involved a considerable number of products, and affected most of developing and developed countries. China is the largest developing country of the world, and also gets rapid development in trade. Compared with other countries, the non-tariff measures that China’s export encounters are more complicated, especially for the export of mechanical and electrical products. Therefore, taking research on the principle and effects of non-tariff measures, not only can help deal with foreign non-tariff measures, reduce or eliminate the restrictions of all barriers, but also strengthen and improve the construction of China’s trade relief measure system, which can create a good external and internal environment for the export of mechanical and electrical products. The research is significant in both theoretical and practical aspects. At present, there are not too many effect and empirical studies on non-tariff measures that are related to China’s mechanical and electrical products, so, this paper will focus on it. After getting large amounts of data and comparing with the research of domestic and foreign scholars, the author selects the improved frequency ratio method to measure the extent that the mechanic and electrical products encounter non-tariff measures. On this basis, the author also chooses technical measures, green measures and patent measures as the main non-tariff measures, and analyzes their long-term and short-term effects respectively. In addition, the paper tries to break convention, not only analyzes that how to cope with foreign non-tariff measures, but also how to set up non-tariff measures to protect China’s electromechanical industries. This is also a research focus of this paper. The paper is divided into five chapters. Chapter one analyzes the research background and methods at home and abroad. Chapter two focuses on the content and category of non-tariff measures, and also analyzes their new trend and characteristics in recent years. Chapter three conducts a detailed analysis on the status that China’s mechanical and electrical products encounter the main non-tariff measures, and measures the extent through the empirical analysis.Chapter four focuses on the influence of technical measures, green measures and patent measures on China’s exports of mechanical and electrical products. Chapter five puts forward some methods to cope with non-tariff measures, and set up some reasonable measures to restrict import to protect China’s mechanical and electrical industries according to our own conditions.
