It has an important significance for realizing waste recycling and improving eco-environment to prefect straw marketization system and sufficiently stimulate farmers’ straw marketization behavior. Based on 427 copies of investigation data on farmers,influence mechanism framework of farmers’ straw marketization behavior is constructed,and key factors of farmers’ straw marketization behavior are analyzed. Results show that farmers joining in straw marketization account for 42. 1%; in influence factors of farmers’ straw marketization behavior,cultivated land area,market price level,logistics satisfaction and air quality perception have significantly positive impacts on farmers’ straw marketization behavior,while education degree,agricultural income proportion and traffic convenience have significantly negative impacts on farmers’ straw marketization behavior. Therefore,it needs strengthening propaganda intensity,carrying out reasonable subsidies and support,encouraging and breeding new type of organization,and establishing and improving the price mechanism of straw marketization to perfect straw marketization construction.展开更多

Hubei is a major agricultural province in central China,and the healthy development of Hubei seed industry plays an important supporting role for the stability and prosperity of the national seed industry. Based on analyzing the scale and characteristics of Hubei seed demand,the market value of Hubei commercial seed is evaluated,the problems of Hubei seed industrial development are discussed,and some recommendations are put forward to strengthen development of Hubei seed industry.展开更多

According to the development demand of grain industry in Hubei Province and the national development plan of grain e-commerce,this paper analyzes the development trend of grain e-commerce in Hubei Province,and expounds the main factors restricting the transformation and upgrading of grain circulation mode in Hubei Province: lack of e-commerce talents;risks for food enterprises to conduct transactions in the platform-type e-commerce; risks in the security of third-party payment. Finally,this paper points out the effective ways of further development of grain e-commerce in Hubei Province.展开更多
