The ＂new＂ in new normal means different to past; the ＂normal＂ means relatively stable. For a period of time in the future, the decrease of potential growth rate has become an indisputable fact. Social security fund is an important source of funds for the protection of people＇s livelihood, whose every movement often attract much attention. Under the situation of new normal economy, how to ensure the preserving or increasing value of social security funds on the premise of security is the core task in the operations management of social security fund investment. At present, there are some difficulties in the development of the social security funds, such as the management system and operation mechanism are not perfect, some institutional measures have not been fully implemented and the progress of the law and regulations is slow. In this paper, we will put forward some corresponding improvement measures, such as expand the scope of social security fund investment, accelerate the implementation of the nominal account system and strengthen the actuarial management of social security fund.展开更多

During analysis and interpretation of data, some touch of context is also given to clear the picture of weakness and strengths of project theory in terms of context. The main objective of project under study was to provide alternative energy to the communities living inside forest to reduce wood cutting for domestic purpose. Though there were many short term surveys were conducted during project, such as, average wood consumption at household level, community motivation survey. Instead to all MRDS （Mehran Research ＆ Development Society） felt need to conduct a detailed impact evaluation to see overall impact of project implementation and review on the life of end users or communities. After three years of project exit, MRDS conducted a qualitative impact study of project in the end of 2014. There were three key questions to explore during study： What was the overall impact of project on end users？ What the best practices of project and why？ What are project learnings and how？展开更多
