And we put forward the following rational recommendations for improving the competitiveness of processing industry cluster of livestock products in Inner Mongolia: (i) The government should increase capital input, focus on supporting processing industry of livestock products, and give play to the guidance and aggregation effect of financial funds; (ii) In terms of enterprises, it is necessary to vigorously develop leading enterprises, to give full play to the cluster effect of the leading enterprises.展开更多

This paper takes the supermarket consumers as the study object. Through on-site questionnaire survey, we find that consumers' awareness of genetically modified food is not high in Yanbian Prefecture, and their willingness to buy is also low; the prices of genetically modified food, consumers' income, educational level and so on, are the main factors that affect the willingness to buy. Based on this, we put forth the relevant recommendations: increasing publicity efforts to safeguard consumers' right to know and choose; increasing supervision efforts to improve the existing regulatory system of genetically modified food; actively organizing forces to carry out the study on safety of genetically modified food.展开更多
