| Research related to safe and sustainable development of enterprise has been a long history.Back in the seventies,self-organization theory was firstly used in management science,which regarded the enterprise as an open complex system and had a profound impact towards thinking and researching methods.In the eighties,researchers took the enterprise as evolutionary system and put the research into a new area.In the nineties,the research of dynamic evolution often adopted the ecological view point.Until the 21st century,the problem of enterprise' dynamic evolution has always been a focus point,well, as large state-owned energy companies,the safe development of grid companies are greatly related to national security,economic development,social stability and people's lives and property.Under the global economic integration background,grid companies are facing global challenges from everywhere.How to survive in huge and complex dynamic systems and adapt to the changing environment at any time has been urgently need to be addressed.Though the current research on enterprise' dynamic evolution,it is found that most researchers either use the theory in a single view point of biology or ecology and the researches about energy enterprise mostly remained in the process of macro-management idea.The paper analyzed the mechanism of enterprises' evolution from the macro to the micro by combining the contemporary mainstream basic principle together,furthermore, demonstrated the evolutional mechanism of Northwest Power Grid Co.,Ltd's safe development in-depth and connected with the results of "Research on safe development strategy of the Northwest Power Grid Co.Ltd" commissioned by its safety supervision department,took SWOT technological matrix to analyze the status quo of the Northwest Power Grid Company's,concerned on the characteristic changes of different evolutional stages and managed the company according to the changing conditions,finally built the pattern of the Northwest Power Grid Company's safe development. |
