Can pigs compete for advantages after China's accession to WTO

Introduction: pig feeding plays a major role in China's animal husbandry economy 5sq pig feeding plays a major role in China's animal husbandry economy, and the output value over the years accounts for more than half of the output value of animal husbandry Live pig, frozen pork and canned pork are China's bulk export commodities, with a steady upward trend In 1995, 2.53 million live pigs, 154000 tons of fresh frozen pork and 638.22 million tons of canned pork were exported, with a total foreign exchange earning of 650 million US dollars The 5sq domestic resource cost coefficient shows that China's pigs have a comparative advantage from 1990 to 1995 From 1990 to 1995, the domestic resource cost coefficient (DRCC) of pig in China was 0.32-0.44 (all less than 1), the comparative advantage was 0.56-0.68, and it was relatively stable, which meant that only 0.32-0.44 units of input cost was needed to earn 1 unit of shadow income The calculation of 5sq social net income (NSP) shows that the allocation of pig production resources in China has a certain efficiency From 1990 to 1995, the whole society can get 0.99-2.71 yuan per kilogram of pork produced in China The calculation results of 5sq effective protection rate (ERP) show that positive protection enhances the international competitiveness of pigs to a certain extent Due to the importance of pork in daily consumption and export of livestock products, China has been taking more active protective measures for pig breeding From 1990 to 1995, the effective protection rate of pigs in China was between 0.15 and 0.57 Further analysis of the reasons for the change of the domestic resource cost coefficient of pigs from 19900 to 1995 shows that the opportunity cost of domestic resources of pigs is on the rise (up 63.96% in 1994), so that the comparative advantage is on the decline (down 0.03% in 1994) Therefore, we should pay attention to controlling the rise of domestic cost in the future, otherwise we will lose the comparative advantage 5sQ 5sQ
