正面作用
1、环境壁垒及绿色标准在客观上促进了可持续发展的实施。经济建设和环境保护是任何国家发展过程都会遇到的一对矛盾。但眼前的经济利益往往会使人们选择破坏环境进行经济建设的道路。尤其在一些发展中国家，由于资金有限，根本无力去顾及环保。毁林而猎、竭泽而渔的做法使现在地球的环境急剧恶化。就算在我国，虽然

早已把环境保护作为一项基本国策，但据不完全统计，1998年全国影响生态环境的产品出口金额达86亿美元，占当年出口总额的6.2%；2000年污染较重的产品(如染料、皮革制品、印染品、纸浆等)的出口达110亿美元，占当年出口额的5.1%。而绿色标准的实施将迫使我国企业在生产过程中减少对环境的污染，采用绿色生产体系生产绿色产品。这在客观上会促进我国可持续发展战略的实施。同样，在一定程度上也会促使世界经济的发展和世界环境的保护趋向协调和平衡，有利于在发展世界经济的同时保护整个地球的生态环境。2、不断提高的检疫标准和包装设计标准，促使各国要不断提高本国产品的质量和卫生及安全性能，这对人类的性命安全和身体健康是有积极作用的。尤其是现在世界各国动植物流行病（如口蹄疫、疯牛病、小麦的矮星黑穗病、玉米细菌性枯萎病等）时有爆发，再加上转基因产品（GMO）的安全性仍无法科学测定，所以在国际贸易中，各国制订相关的检疫标准并严格执行是非常必要的。

The verview and impact of technical barriers to trade
Technical Barriers to Trade based on national or regional technical regulations, protocols, standards and certification (conformity assessment procedures) and other forms, involving wide-ranging, covers science and technology, health, quarantine, security, environmental protection, product quality and certification, and many other technical indicators system, used in international trade, which, showing a flexible, numerous regulations. As such a large number of barriers to technology emerged, so often an appearance of legitimacy, become the most covert international trade, the most formidable non-tariff barriers.
With the rise of the tide of economic globalization and trade liberalization, together with the relevant WTO rules limit the types and forms of international trade barriers are constantly changing: Getting lower and lower tariff rates, the traditional non-tariff barriers are gradually reduced, the new, more flexible, more subtle barriers to trade - but in the continuous development of technical barriers to trade, species are on the rise. China has joined the World Trade Organization, so in international trade, we must follow the relevant WTO rules and international practice act. Faced with these new changes we should how to deal with, resulting in the protection of world trade and China\'s foreign trade interests in a more open environment to promote the health of China\'s economic and social development? I would like to propose appropriate measures necessary to clarify before the international trade protection as a means of intensifying the underlying causes of technical barriers to trade:1. Safeguard the interests of all its fundamental purpose of international relations. Although the order to advance economic globalization and trade liberalization, countries in the Uruguay Round commitments to further reduce tariffs and to maintain the status quo in the gradual elimination of all non-tariff barriers. But now, increasingly fierce international competition, countries in order to safeguard its trade interests in the WTO to phase out clearly contrary to the spirit of some of the traditional non-tariff barriers at the same time continue to introduce more subtle technical barriers to trade, and numerous, requiring increasingly more demanding. In developed countries, between developed and developing countries, there are technical barriers to trade among developing countries. Only because of the technical level, developing countries are far lower than developed countries, so a greater impact on developing countries of technical barriers to trade. 2. Many of the exceptions and loopholes, but also for the implementation of technical barriers to provide a legal basis. Such as Barriers to Trade Agreement

the environment, as long as these measures do not think that the countries with the same conditions result in any unreasonable discrimination, or to become disguised restriction on international trade as a means Again, Application of Sanitary and Phytosanitary Measures Agreement, or health of the sanitary and phytosanitary measures scientific basis and the measures appropriate to the level of protection be implemented or maintained higher than the international standards, guidelines and recommendations of the measures.to trade has great legitimacy. 3. National and international environmental organizations are constantly improving the status; influence on government decision-making is growing. Therefore, governments have implemented such a policy; have to consider their voices, the parties to make concessions, increased trade barriers. As the global environment continues to deteriorate, causing the concern of the international community, since the since the 1970s, global environmental organizations have been established, more well-known, such as Greenpeace, international environmental film group, the World Wildlife Fund . In many countries have established sub-sector, with many members, a wide range of environmental information, and strongly oppose the governments of various environmental destruction, urged governments to implement sustainable development of economic and social policies. Once in the EU under pressure from environmental groups, many times to raise the environmental standards to reduce the production process and increasing environmental pollution on human health and life protection. 4.As mentioned earlier, the world\'s environmental problems have attracted national attention to the people and government, sustainable development is the public. Therefore, countries in international trade in order to obtain a more favorable position in the gradual elimination of some of the clear violation of the spirit of the WTO\'s non-tariff barriers at the same time, brings up the banner of sustainable development, are increasingly turning to the health and quarantine standards and the environment protection standards and people\'s health and sustainable development of non-trooped countries). Therefore, countries implement is nothing to fear, and standards are becoming increasingly demanding, more and more types. This is the main technical barriers to trade intensified.
