In society, and in marriage, exchange plays a major role. Because of the division of labor goods are exchanged within society and between different societies. Within marriage, exchange of different kinds of use values also plays a major role, and Ibsen is certainly aware of this: Marriage is a contract that explicitly or implicitly oblige the spouses to take care of and service each other in different ways. And this article attempts to prove that this is the core conflict in the pay.展开更多

The survey results revealed cash gifts to be the second-largest expenditure(1,330 Yuan) for rural households, far beyond the average spending on health(854.1 Yuan) or education(890.8 Yuan). The amount of cash-gift expenditures indirectly reflects a family's social relations level, and our developed Social Relations Extent Coefficient—based on cash-gift and food expenditures—can directly reflect the extent or level of these relationships. Different types of farmers or farming families have different coefficients. The coefficient also shows how social station affects a family's water resource utilization, and how water is distributed among different types of farmers. Despite the current inequities, however, promotion of better agricultural techniques and large-scale cultivation in this area could help distribute water resources more equitably and effectively.展开更多

Most of the 44 categories of light industries, several tens of thousands of enterprises mainly in economically developed areas, are undertaking the production of gifts. It was known that only in Shenzhen City, there are over 1600 gift-making enterprises. Their annual output of gifts exceeded 13 billion yuan, and annual export reached 1 billion US dollars.展开更多
