Thus, while the world green tendency and the green demand rise increasingly, the research on the green cultural management is becoming more important. The study of the green cultural management is not only of vital significance in promoting the continuous development of social economy, but also exchanging the way of the economic growth from extensive pattern to intensive pattern, improving the capacity of the competition and economic benefit of the company, and accelerating the international business. Moreover, the research has another significant importance in enriching and developing the science of enterprise of management.展开更多
