文摘With the rapid development of the global economic tide,the economic development has entered a new stage.The traditional pattern of economic development gradually farewell to history and the cultural industry is striding forward in a brand-new posture into the public's view.Culture is the soul of a nation;it brings not only a gift of value,but also a new economic growth point.Whether this economic turning point can be grasped or not is crucial to the development of the regional economy.This paper will make a brief summary of the cultural development and cultural industry in Yanbian,which hoping to find out the problems and provide some constructive suggestions for the long-term development of the cultural industry.
