With the deepening of the reform and opening up and modernization in our country gradually accelerated, the public’s daily life are increasingly linked with public affairs. In an increasingly open and expand in the field of public life, how to participate in social public affairs more effectively and better defend social public interest, in short, how to cultivate the social public spirit has put on the agenda. As academic category of "public spirit", the most profound theoretical origin can be traced back to the "public" theory in western political philosophy, the "public" in the philosophy of Chinese traditional political philosophy, and "public" in Marxism philosophy. Looking from the connotation, public spirit is conceived in social public life internalization in the public mind to participate in public affairs and safeguard the public interests as the proper attitude, ideas and activities combined. The characterization for the modern society a qualified social members should have a series of social public ideas, and to cultivate public spirit is the national modernization construction, government administration and government governance and tremendously beneficial in building a harmonious socialist society, etc. To probe the evolution of public spirit, the public spirit of contemporary Chinese society must be on the basis of Chinese and western social public spirit. The lack of public spirit in contemporary China has its practice in reality. Under the urgent situation of social structure transformation, the first encounter is the fact that the public morals is landslide; And with the rapid development of social economy, on the one hand is the public public awakening of consciousness, to the contrary is relatively inefficient public participation; Thus in the field of public life is increasingly open society public, faces a public communication nominate caught on; Finally, in the process of social and public grow in our country, the folk organization is in the absence of social public life. Meditation of China’s public spirit fosters difficult aspect, there are mainly four factors in restricts the social public spirit bred in China. One is the traditional Chinese culture of continuous immersion, public or private promulgation and values inhibits the growth of public spirit. Second is the erosion of the negative effect of market economy, the profit of individualism thought and behavior of public spirit. Third is the national will to extrusion of public life in some extent, under the universal political atmosphere, the breeding of public spirit space crunch. The fourth is the concept of the rights and obligations of blanking, the notion of "private society" mentality that the public to enjoy the rights at the same time but afraid to bearing as the compulsory responsibility of public spirit. Thus, on the cultivation of social public spirit in contemporary China, the first, on the base of connection of the rule of law and the public, the law modernization and public spirit, we must highlight the social public spirit in the perspective of the rule of law. The second, In both international and domestic social trend of governance and good governance, the government governance of public administrative spirit to guide the production of social public spirit. The third is to the public reading and practicing of public spirit in public force of self cultivation value root public spirit. The fourth is the socialist core values education as an opportunity to help in the cultivation of social public spirit. In a word, the public spirit of exploration and research in contemporary Chinese society is still an unfinished task. Generally, cultivation of public spirit depends on not only both the national public consciousness of social norms and moral consciousness,but although more and more taken from practical living reality of social undertakings.
