The results show that the safety degree of Hunan agricultural industry is always in the range of " basically safe" and above,it was in the range of " safe" in 2010 and 2011,in the range of " very safe" in 2013,and in the range of " basically safe" in the other years; the indices of productive force,competitiveness and dependency of agricultural industry is always in the state of " basically safe" or above,while the index of control force of agricultural industry is in the trend of changing from " basically safe" to " unsafe". Therefore,it is necessary to accelerate the innovation process of agricultural industry and improve the export quality of agricultural products,especially to establish a stricter market mechanism for foreign capital entry and foreign capital merger and acquisition,improve the control power of agricultural industry,and provide favorable guarantee for the safety of agricultural industry.展开更多

For example, computer, mobile phone, etc. are increasingly popular, especially hi-tech products updating more and more quickly, which has initiated some problems: resources depletion, environmental pollution, ecosystems damage, etc. While people are enjoying convenient and comfortable life from hi-tech, they are worrying about quantities of e-wastes discharged. In order to reduce the amount and harm of e wastes, this paper starts from the connotation of the ecological stability of circular economy electronics industry chain (CEEIC, for short), uses the food chain principle for reference to describe the links and connection of the electronics industry chain, and selects factors from the three link: production, consumption and recycle to construct indexes system based on their characteristics, with which a scientiflc evaluation is carried on for CEEIC by using fuzzy comprehensive evaluation.展开更多
