However,because of the defect of the market economy,enterprises are difficult to carry out green supply chain management spontaneously. In order to solve the above problem,the feasibility of the government as an external driving force to lead the implementation of green supply chain management was studied,and then a mixed guidance model of enterprise green supply chain management was established. In addition,the mechanisms of the government encouraging enterprises to implement green supply chain management were discussed,including negative punitive measures( fines and taxes) and positive incentive measures( subsidies and tax reduction) and the supplementary function of environmental credit system policy to realize government-led green supply chain management,which provides certain guiding for achieving the sustainable development of enterprises and society.展开更多

The properties of EI are obtained by embedding a single inclusion with the interface into an infinite matrix. However, whether such an EI is universal for different micromechanics-based methods is rarely discussed in the literature. In this pa- per, the interface energy theory is used to study the applicability of the above mentioned EI. It is found that some elastic properties of the EI are related only to the properties of the inclusion and the interface, whereas others are also related to the properties of the matrix. The former properties of the EI can be applied to both the classical Mori-Tanaka method （MTM） and the generalized self-consistent method （GSCM）. However, the latter can be applied only to the MTM. Two kinds of new EIs are proposed for the GSCM and used to estimate the effective mechanical properties of nanocomposites.展开更多
