3.1 Establishment of the interest chain
On the basis of reference for other industry interest chain,we divide the interest chain for the antibiotics into three parts：Producer,Distribution process and Consumer.Different parts has different functions and also has different benefits from the antibiotics.
The producer mainly includes the production enterprise which produce the antibiotics and sell the antibiotics to the market.The distribution process includes the distribution enterprise,the hospital and the retail drugstore.Due to the strict control from the government on the circulation of the antibiotics,the distribution process can only be completed by the authorized hospitals or enterprises.And the doctors prescription is essential when you want to buy the antibiotic medicine.So,the doctor is the important terminal conductor for the use of antibiotics.The last part of the chain is the consumer.Patients and farmers are both included into this part.According to the related study,the majority use of the antibiotics is from the farmers who raise cattle for sell.
Finally,we establish the interest chain for the use of antibiotics which is vividly shown in the Figure 1.
