【正文】 as for the developing countries, the lower export cost of laborintensive products is one of their parative advantages. The uniform of labor standard will increase the cost and burden which will weaken their advantage and lead to weaken or close the foreign trade of the developing countries. However the developed countries can transfer their cost to the end users. 5) If the developing countries stand more quotas in one line or some product in international trade, the change of export will influence the international price of the product, such line or enterprises may take the integration of Occupational Safety amp。 Health, straight out the relations between the system and mechanism in safety produce and supervision。 in the meanwhile, our export enterprises ought to adapt the developing trend of the target market including green safety production, research and develop the green and safe product that are good to safety protection and the health of the public, raise the petition of international trade [6, 7]. Nowadays, China belongs to the developing countries with rapid development, it is not up to the standard of developed countries in some safety protection. We trust that we will reach the standard in of the developed countries in the safety protection with the rapid development of productive power. In some developed areas and cities, some pletive enterprises are trying their best to influence the international market price. Therefore, we should make an overall plan with due consideration when we take the stand of safety and international trade. In addition, we should publicize the safety culture of enterprises, our decision makers, managers and staff of safety management should realize the challenge of occupational safety amp。 on the contrary, the producers in export countries will undertake more proportion of the total cost. In Fig. 2, the total ine of given export product in big countries is P1E1Q1O in the condition that they do not take active steps to prevent accidents, occupation disease and are lack of safety incest。B. We must point out that if the accident, occupation disease will worsen native safety, and it can directly threaten the quality of export goods. Export petition will be influenced in small countries if the small countries do not prevent or control safety accident, occupation disease. C. Influence of Increasing the Safety Investment in Big Countries to the Total Costing in Export Goods “Big countries” in international trade mean the countries that stand more quotas in international trade, they can influence the given price in international trade. If the big countries takes active steps of preventing accidents, occupation disease, the total cost will be up, which make the international market inadequate supply, then the price will be fluctuated, so the big countries can make up for upward cost by increasing the price of product, and reduce export petitions of preventing accidents, occupation disease. As for the conditions of the big countries, we can note and analyze by following Fig. 2. Fig. 2. Big countries in export and international market price. In Fig. 2, axis X and axis Y indicate the same variable to Fig. 1. D is the import demand curve that foreign countries will meet the export goods of big countries. As big countries have abundant quantity, the export quantity will influence the international market price of these export goods, therefore, D is a curve of rightbottom. Sx is an export supply curve that big countries do not take steps to prevent accidents, occupation disease, the international market price is Pl, the export quantity is Q1， produce surplus that big countries can gain from the export goods is PlElA. If the big countries take active steps to prevent accidents, occupation disease, the total cost including productive cost, the cost of accidents, and preventive cost of occupation disease will be up, too. But the big countries stand the important position in international trade, the reduction of export quantity will lead to the upward price of the given product. In Fig. 2 ， the international market price in big countries is from P1 to P2. that is to say, the unit price of big countries export goods increase P3P2, but the accident loss that big countries undertake, preventions for occupation disease or cost of control is P3P1, the rest (P1 P2) are transferred to the import endusers. Therefore, preventing accidents, occupation disease make the export supply curve move (from Sx to S39。 secondly, productive accidents, occupation disease lead to some loss, but it has no threaten to native export, so it can reduce total export cost without taking steps. In addition, whether safety protection can influence their product’s petition depend on their costs as well as their prices. It is more important that we should judge your countries in some products big countries or small countries. B. Influence of Increasing the Safety Investment in Small Countries to the Total Cost in Export Goods “Small countries” in international trade mean the countries that stand small quotas in international trade, they can not influence the given price in international trade. If the small countries (the developing countries) takes active steps of increasing safety invest, then the total cost including productive cost, the cost of accidents,
