【英文摘要】 In the perspective of the regional social cultural study this dissertation reviews and discusses deeply and widely the series changes emerged in the social lives in the Jiangnan Delta during the period of mid and late Ming Dynasty with the purpose to post the origins and the historical meanings of those changes in terms of the region as the whole country.Firstly from the spatial-temporal angles of the history and the region this dissertation reviews and analyses the politics, economy, society, culture, traditional customs, and the ecological environment in the Jiangnan Delta in order to argue that the changes in this area during the period of mid and late Ming Dynasty can not be summed up as a single or any individual momentum, but should be treated as the result of the multi-momentums. Secondly through probing into the family structure and relationship among family members, the development of the kindred organization and the social function, and the thrive of folk association and the impact of them this dissertation opens out that there were violent movements and obvious changes in the traditional social relationship with the core of social stratification during the period. Thirdly, it also studies the social lives in the Jiangnan Delta at that time from the different angles and different perspective.
