【正文】 rend for Harmonization of Safety and Health Standards (HSHS) [3]. During the past decade, the developed countries have been busy with putting the social clauses into the international economy the trade system, Under the flag of “caring on the human rights in developing countries” they arouse the questions of “l(fā)abor standards”, that is to say, they relate the nation’s safety, productive questions with international trade, it is a “green protection” in nature. For a long time, in view of weak economic infrastructure, low productive capacity, lack of capital, low industrial technology, backward management system and soft supervision, many accidents occurred in industrial and mineral enterprises, accidents of workers for injury and dead, occupation disease occurred frequently, There are many questions in safety production,paring with the developed countries, there are the gaps that we can not reach the claims of “public international labor standard” [1], the safety conditions are very stern now. Some industrialized countries such as America and European Union note: with the rapid development of international trade and developing countries gaining more and more change to take part in the world economic trade, the differences of Occupational Safety amp。 Health, the government representatives and experts of some western countries such as USA and Germany put forward this question again and again [1]. There are some stipulations in North American Free Trade Area: Only the countries or regions that take the same Occupational Safety amp。 health condition. The developed countries are do their utmost to take the same activity and pander International Labor Organization (ILO) to carry out this strategy. By the end of 90s in 20th, International Labor Organization tried to turn Occupational Safety amp。 health standard integration. On the 15th World Occupational Safety amp。 health evaluation and standardized management system according to the No. 155 and convention like ISO9000 and ISO14000, evaluate the condition of enterprise safety amp。 health documents, it published the norm and directory of it’s OHSMS before 20xx. Nowadays, HSHS is not only slogan of conference, but also the international agreeable action. And the derived labor standard is one of thefocuses in international anizations such as WTO, and more and more countries give more attention on it. Safety production will e into being important influence on the economy of China and the social development [4, 5]. The authors will attempt to analyze the relation of safety cost and international trade by the relative theories of economy, understand the crucial reasons why the developed countries relate Occupational Safety amp。 health standard integration, labor standard with international trade, it is necessary for us to deeply analyze and discover its advantage and disadvantage and seek the relative measurement to realize the win/win of the safety production and economic development. Here we will take the economics analysis on relation of safety cost and international trade in a short time. As for an export enterprise, the cost of safety protection will influence their product’s price as well as the export price, which will influence their parative advantage. Objectively speaking, there are some countries dare not take active steps on safety protection, they worry about the strict safety protection will influence their product international petition. A. Influence of Safety Invest to the Total Cost in Export Goods Increasing the safety invest, preventive charge or taking measurement according to accident, occupation disease, as for the total cost of export product, it perhaps will have the following influence： 1) If we adapt some aftermeasurement to deal with accidents and occupation disease, it will increase negative safety invest, therefore, it will increase the total cost the export goods. 2) If we reduce the accidents in production, occupation disease by safety production, it is possible to increase or decrease the safety invest, thus it is uncertain to raise the total cost of export goods. But it need the conditions of high safety technology, high oneoff invest, high safety training and higher management. In the following analysis, we do not consider the condition of realizing the win/win both economic development and safety protection. 3) if we are lack of safety invest, preventive charge or taking measurement according to accident, occupation disease, there are two possibilities: firstly, frequent productive accidents, occupation disease make tremendous loss, influence mon production, then it can threaten native export, force the enterprises to prevent and control the accidents, thus increase the total cost。) and the export quantity is drop (from Q1 to Q2). In the meantime, produce surplus of small countries drops to triangle P0E39。x) and the export quantity reduce (from Q1 to Q2), the produce surplus of big countries will reduce from PlElA to P2E2B, P2E2B is larger than PlCB (produce surplus in the fixed international market price). From Fig. 2 we can see: If the big countries take active steps of increasing safety invest, then the total cost including productive cost, the cost of accidents, and preventive cost of occupation disease will be up, the loss will be shared by the endusers in
