Chapter 3 draws from secondary materials and literature to review the history and evolution of social health insurance in contemporary China (since 1949), providing the historical background and the economic context of China’s social health insurance expansion in the 2000s. It shows that throughout the history of contemporary China, social welfare was never considered a basic social right for citizens. Despite dramatic changes in the coverage and generosity of social health insurance across different developmental periods, the stratification of Chinese social health insurance is persistent and was reinforced during the social health insurance expansion between 1999 and 2011. Moreover, the economic transition and the diversification of regional economies in China constitute the economic context, in which the Chinese central and local leaders’ motivations for and differential responses to social health insurance expansion take shape.

In order to solve the inserting order scheduling problem of agile supply chains which already have fixed production plans, a two stage supply chain which consists of one factory and many suppliers is studied. Take minimizing the total supply chain cost as the objective, an Integer Planning (IP) model is designed to describe the scheduling problem based on the time slot representation of corps’s available schedule periods, and a Neighbor Value Partial Interchange Simulated Annealing algorithm(NVPI-SA) is proposed to optimize the IP model. Finally, the practicality and effectiveness of the model and algorithm is verified by scheduling experiments.

With rapid development of society and economy, the issue of water shortage has presently been more and more serious in China. Optimal water and land resources allocation, involving many aspects such as society, economy, ecology etc., is a rational approach to solve this problem. In this study, a substantially improved model, i.e., multi-objective optimal allocation, is established for coordinating the usage of water and land resources. The model was developed on the basis of Immune Genetic Algorithms (IGA), and it mainly includes three objectives and seven constraints. The results of case study show that there is no water shortage in the predicting year of 2020 in Dongtai City, Jiangsu Province by using the optimal allocation of water and land resources. The new optimal allocation proposed in this study has a positive influence to promote the economic and social harmonious development and the natural environment protection for coastal areas of China.
