Taking agricultural workers as the research object,this paper analyzed factors influencing the implementation of e-commerce of agricultural products. Besides,from the enterprise status,market conditions,and groundings,with the aid of the GEM( Groundings-Enterprises-Markets) model,it evaluated the factors influencing the development of e-commerce of agricultural products. Then,using SPSS software,it analyzed factors and came up with improvement recommendations. The results show that 59% of the respondents are willing to conduct e-commerce,and the status of the enterprises,market conditions and groundings are main factors influencing the implementation of e-commerce of agricultural products. Therefore,it is required to increase industrial concentration,promote cooperation between small and medium-sized enterprises( SMEs),and strengthen infrastructure construction,so as to promote the development of e-commerce of agricultural products.展开更多

Then, it analyzes the competitiveness of agricultural industrial clusters in Hubei Province from three aspects, namely, the foundation, enterprises and market. In the aspect of the foundation, Hubei Province has superior geographical location, rich natural resources, abundant human resources, diversified capital sources, and hardware and software facilities. In the aspect of enterprises, agricultural suppliers (farmers) are relatively scattered in Hubei Province, organizational level of relevant enterprises is constantly improved, and structure and strategy of enterprises are constantly innovated. In the aspect of market, the competition of agricultural products is fierce in local market, and it is difficult to explore external market. Finally, it presents countermeasures to improve the competitiveness of agricultural industrial clusters in Hubei Province, including building agricultural industrial park and cultivating key leading enterprises, strengthening innovation management, and increasing financial support.展开更多

Learning from GEM and Open Quake is helpful to improve the seismic hazard model of China and enhance the scientificity of the seismic hazard assessment for metropolitans and major engineering facilities near major seismogenic structures.展开更多
分析了电阻率和电阻几何系数对基于炭黑/硅橡胶的力敏导电橡胶的"正拉力-电阻特性"(positivetensile coefficient of resistance,PTCR)的影响程度,揭示了力敏导电橡胶拉伸过程的电阻变化机理。在一定拉伸范围内(40%),当导电...分析了电阻率和电阻几何系数对基于炭黑/硅橡胶的力敏导电橡胶的"正拉力-电阻特性"(positivetensile coefficient of resistance,PTCR)的影响程度,揭示了力敏导电橡胶拉伸过程的电阻变化机理。在一定拉伸范围内(40%),当导电填料用量处在渗流区中心时,电阻率的增大是引起PTCR效应的主要原因。随着导电填料用量的增大,电阻几何系数的增大成为引起PTCR效应的主要原因。在某一特定导电填料范围内,力敏导电橡胶的"正拉力-电阻特性"还与拉伸长度有关。拉伸长度较小时,电阻几何系数的增大在PTCR效应中占主导;拉伸长度较大时,电阻率的增大在PTCR效应中占主导。展开更多

文摘Firstly, this paper summarizes concept of the agricultural industrial cluster and GEM model. Then, it analyzes the competitiveness of agricultural industrial clusters in Hubei Province from three aspects, namely, the foundation, enterprises and market. In the aspect of the foundation, Hubei Province has superior geographical location, rich natural resources, abundant human resources, diversified capital sources, and hardware and software facilities. In the aspect of enterprises, agricultural suppliers (farmers) are relatively scattered in Hubei Province, organizational level of relevant enterprises is constantly improved, and structure and strategy of enterprises are constantly innovated.
