Ocean society in China has been developing rapidly these years. The development of ocean society in China can be divided into three periods：“Starting Period” from the reform and opening-up in 1978 to the 1990s as its first period，“Accumulation Period” from the 1990s to the beginning of the 21st century as its second period，“All-round Development Period” from the beginning of the 21st century until nowadays as its third period. It is also found out in this report that the development of ocean society has already been given attention by government，concerned policies and legal construction have been improving continuously，marine hard power has been significantly improving，the idea of ocean society development has shown the trend of diversification，and the coordinated development among different regions has become increasingly necessary. Meanwhile，it also points out that the strategic of ocean society development is not enough，the obstruction from imperfect system and legal institution is still obvious，marine hard power is still falling behind，the unbalanced development among different regions has become more serious，marine ecological environment degradation still remains，and the challenge of globalization is inevitable nowadays. Therefore，it can be forecasted that the overall planning of ocean society development will be strengthened，marine hard power will be improved continuously，new fields of ocean society will develop more quickly than traditional fields，the trend of diversification will be more obvious，and the development of ocean society will depend more on international cooperation and exchange. So it is important to make ocean business planning and policies more strategically，improve marine hard power specifically，carry out ocean management comprehensively，strengthen marine education，and take part in international cooperation and exchange in the field of ocean society development.
