Research on the Influence of Technical Barriers to Trade on China’s Exports: Take Electronic Products Industry as an Example

With the continuous improvement of China’s economic strength and scientific and technological level, China’s foreign trade is also developing rapidly, and technology trade is also prospering. Now it has become an important part of China’s foreign trade. At the same time, with the increasing trade friction, the export of electronic products in China is constantly affected by technical barriers to trade. By studying the short-term and long-term stages of TBT, this paper analyzes its mechanism and its impact on the export and welfare of electronic products in China, discusses its causes and puts forward corres-ponding countermeasures and suggestions.

sholds by developed countries or technologically advanced countries. They are nominally to safeguard the safety of countries and regions, and protect human life and health. The ecological environment is actually to restrict the entry of goods, investment and services from other countries and to protect the domestic market. Therefore, technical trade barriers are widely adopted by countries as an important means to protect their domestic markets and industries and promote foreign trade.
Although China is the largest trading country in the world, it often encounters the impact of technical barriers to trade due to its low technical content and lack of innovation. According to data released by the ministry of industry in China, the 2014 export enterprises in our country suffered a direct loss of technical barriers to trade above $75.52 billion, 2016; the technical trade barriers to China has reached $93.38 billion; the economic losses is caused by the additional cost of $24.75 billion, and by more than 40% above; the export enterprises encounter the technical barriers to trade. Since China's accession to the WTO, 80% of the trade barriers encountered in international trade are technical barriers to trade, and the export volume affected by TBT accounts for about 25% of the total export volume 1 . According to the latest information of the trans-pacific partnership agreement shows that the rules of world trade in goods will further be highly compatible with intellectual property rights, environmental protection, and technical standards. This will also cause China to face more technical trade barriers in the future, and will also affect China's various industrial exports in the next time.

Literature Review of Technical Barriers to Trade at Home and Abroad
Technical Barriers to Trade (TBT) originated from developed countries and regions and was widely concerned by theoretical circles at home and abroad in the late 1970s. As for the mechanism that smuggles TBT into a country's market, we believe that it will bring irreversible sunk costs, which in turn will affect the export decision of enterprises. Bolin Ye on the research background of the technical barriers to trade, show that in the second world war, the development of world trade liberalization, traditional trade barriers, countries to look for new trade barriers is the direct cause of its produce, and the new trade barriers and direct trade between countries export (Ye, 1999); Markusen think technical barriers to trade can cause additional costs to produce and export, the extra cost including fixed cost and variable cost, because different importer of technical regulations and standards vary, this makes the fixed costs of each market all have differences, also makes the enterprise when doing the export decisions will spontaneous choice with low barriers to entry in the market, or don't export, thus affecting trade flows. Therefore, technical barriers to trade, as a kind of cost increasing barriers, affects the export decision of enterprises, so that the flow of international trade changes (Maskus & Wilson, 2001 Wang argue that TBT is caused by the economic differences of various countries and the incomplete information of market mechanism (Gao, 2003). In the existing literature, all think roughly the technical trade barriers on exports and benefits there is a positive or negative impact: Cao and Johnson by studying in New Zealand to enforce beef and mutton in risk management and evaluation system, found that red meat exports growth significantly, thus confirm the exporter of the standard trade promotion effect (Cao & Johnson, 2006). Chunming Zhao and Hao Chen established the two-country model and used the game theory to conclude that as long as the technological gap between the two countries is not large, even if the technological barriers erected by the non-dominant countries can bring benefits and increase exports to their own countries. Junjun Hou also showed through empirical research that the improvement of national standards would promote the increase of export trade in the long run. However, through empirical research (Hou, 2009), Moenius believes that the heterogeneous standards of importing countries will reduce the export of trade but promote the import. In the analysis of china-South Korea trade gravity model (Moenius, 1999), Xiaojuan Chen and Yueying Mu found that the technical trade barriers set by South Korea had an obvious nature of trade protectionism, which inhibited China's agricultural exports to South Korea (Chen & Mu, 2015). Bao Xiaohua and Daming Zhu after building the nonlinear gravity model, and studied the difference of the exporter encounters TBT, found that the higher the per capita income level, production technical level is higher, the higher the government management ability can have more high TBT coping, and makes a long-term TBT may positive contribution to a country's exports, its benefits may also be positive (Bao & Zhu, 2015).

Analysis of the Influence of TBT on Export and Welfare in
Short and Long Term

The Impact of TBT in the Short Term
TBT has a negative impact on exporting countries in the short term. First of all, we can illustrate from the S-D curve, as shown in Figure 1. D is the demand curve of importing country, S is the supply curve of exporting country, E is the initial trade equilibrium point, and Pe is the initial price equilibrium point. Exporters now importing countries technical barriers to trade, in order to deal with TBT, in a short time needs through negotiation or pay additional costs, which in turn makes the S curve to move above again, and the elasticity decreases, and the S curve moves to S*, assuming that importer D curve remains the same, so export prices will rise, and become a P*, exports also decreased.
Secondly, we can also analyze the impact of technical barriers to trade on exports according to the terms of trade. The mechanism is as follows: when TBT is implemented, China's commodities cannot meet the technical requirements of the importing country in a short period of time, so the export volume decreases rapidly, and some unmarketable commodities flow back to China, leading to the decline of domestic prices, the decline of export prices, and the deterioration of  After the implementation OF TBT, the improvement curve OF the exporting country will change to OF* due to the increase OF sunk costs and additional costs. As can be seen from the figure, the terms OF trade will deteriorate to OE* and the export volume will decrease.

The Long-Term Effects of TBT
TBT has a positive impact on exports in the long run. According to the "imitation gap model", technological innovation can promote trade, and continuous technological innovation will make import and export trade continue. The mechanism is as follows: when the importing country begins to implement TBT, the exporting country will produce trade inhibition effect in a short period of time, but in order to continue the trade, the exporting country will carry out technological innovation over TBT for a period of time. In addition, due to the non-saturation of consumer preference, the emergence of new technology will increase the demand of importing country. Therefore, in the case of constant supply, increased demand will lead to an increase in exports.
In time, under the action of each country and enterprise facing the technical barriers to trade is not always the same, with the development of science and technology, new technology constantly appears, so BT will follow the ascension of the new technology constantly improve themselves, so the importer will also continuously improve product quality requirements, so the technical barriers to trade and in the process of technological innovation and stimulate exports has realized the dynamic circulation and upgrade. As shown in Figure 3, the pro-

The Influence of Technical Barriers to Trade on Industry Welfare
Technical trade barrier also can produce obvious effect to industry welfare. As shown in Figure 4, China and foreign countries are the export and import countries of a certain commodity respectively. The horizontal axis represents the supply and demand quantity of the commodity, the left axis represents China, the right side represents foreign countries, and the vertical axis represents the price of the commodity. SX, DX, SM and DM are the supply and demand curves of exporting and importing countries respectively. PW is the transaction price under free trade conditions. If foreign countries now impose technical trade barriers on China's export commodities, China will passively improve the technical quality of export commodities, and the price will also be increased due to technical inputs such as R&D and quality improvement, and the transaction price of new products will be P2. Imports will fall as prices rise. Due to the backflow of some commodities in The Chinese market, the domestic price is reduced to P1, so will the export volume. Therefore, China's consumer surplus will increase the area of D + E, while the producer surplus will decrease the area of A + B + C + D + E, while the exporter will gain the area of B + F by virtue of their technical advantages. Therefore, due to the implementation of technical barriers, the net impact of industry welfare effect will be F-A-C. Therefore, the positive and negative of industry net welfare depends on the respective size of F, A and C.

A Case Study of China's Electronic Products Export Encounter TBT from the United States
Electronics is one of the most important export industry in China the development of electronic products is not only related to the development of the electronics industry in our country, also with the development of the electronics industry in our country, and electronic products export market in our country, the United States is China's largest export country, at the same time, our country is the largest country in the affected by the TBT.  This paper will analyze the data of electronic products exported from China to the United States in recent years, so as to discuss the impact of technical barriers to trade in the United States on China's electronic products.
According to the law of the People's Republic of China Ministry of Industry and Information Technology published data available electronic products exports to the United States in China, in 1993 China's exports to the United States electronics trade totaled $1.95 billion, China to become the second largest importer of electronic products, the US market since then, China's rapid growth of electronic products exports to the United States, from 1995 to 2001 in just six years, China's total trade rose from $3.69 billion to $10.64 billion, and since 2002, due to the impact of technical barriers to trade in the United States, the percentage increase short-term slowdown, but total trade is still increasing year by year, In 2007, China's export volume of electronic products to the United States exceeded 50 billion US dollars. In 2016, China's export volume of electronic products reached 93.16 billion US dollars. It can be seen from this that with the continuous development of Sino-American trade, the volume of China's electronic products exported to the United States is also expanding. By China's export trade on electronic products to the United States can be found that since 2001, the electronic products trade, China's exports to the United States, has shown a steady rise in status, in 2001 China's exports to the United States of electronic products trade for $10.64 billion, for $93.16 billion to 2016, during this period, China's overall trade shows continued positive growth trend. According to Figure 5, it can be seen more intuitively that China's export of electronic products to the United States is gradually tending to be reasonable and stable.
When China's foreign trade is developing rapidly, the United States frequently uses safety, green, environmental protection and other excuses to constantly implement technical trade barriers against China's electronic products export, so as to achieve the purpose of protecting the American own electronic industry and protecting the interests of its consumers. According to the latest statistics of the Ministry of Industry and Information Technology, China has nearly 70 percent of electronic manufacturers, more than 40 percent of electronic products have encountered the United States set up technical barriers to trade, the annual loss of tens of billions of dollars, it can be seen that China's electronic products export is facing the United States technical barriers to trade serious restrictions.
With the continuous progress of science and technology and the continuous improvement of consumer demand, consumers' dependence on electronic products is also increasing. At the same time, indicators of all aspects of electronic products must also be constantly improved. The United States has issued more and more technical trade barriers to electronic products, so China's electronic products export trade is facing an increasingly difficult situation. Among them, electronic products, such as electronic components, household consumer goods, computers and communication equipment, face the most significant technical barriers to trade in the United States. In recent years, with electronic products export trade in our country, our country's electronic products in the export process has encountered technical barriers to trade restrictions in the United States, the most typical event is "Blocking Huawei and ZTE event": in 2015 the United States intelligence committee banned Huawei and ZTE electronic products mainly export enterprises in our country. During this period, as the technology of electronic products in China could not be improved in time, the export volume showed a downward trend. As shown in Figure 7, since June 2015, China's export volume of electronic products has shown a trend of decline. It can be seen from this that technical trade barriers have played a role in inhibiting the export of electronic products in the short term.
Through the above data and theoretical analysis, we can know that the implementation of TBT in the United States, for example, will hinder the export of electronic products in China in the short term. This is because in the short term, enterprises are still unable to face higher barriers costs and carry out technological innovation quickly. In the long run, it has a promoting effect, because in the long run, more understanding of new technical standards in technical barriers to trade, can develop better products to expand the market, thus driving the increase in consumption, and then increase in exports.

Policies and Recommendations
China's electronic products in the export trade encountered technical barriers to trade problems, in most cases, because China's understanding of technical barriers to trade is not enough, but also some countries in the process of setting up technical barriers to trade and implementation is full of hide and other reasons.
Therefore, in the current situation of trade pattern, we should strengthen the re- At the same time, our country should also actively respond to bring the negative impact of trade barriers, and starting from the long-term interests of our country, combine the actual conditions of our country national condition, such as the level of productivity development, scientific and technological level, environmental conditions, etc. seriously and formulate internal technical innovation policies, and implement the strategy of "innovation to promote the reform", so as to provide the conditions for realizing technological leapfrogging.
