政策碎片化对耕地“非粮化”的影响及其治理对策 ——以Z市J区Y镇为例

以耕地“非粮化”面积达90%以上的Z市J区Y镇为案例,研究了政策碎片化对耕地“非粮化”的影响及其治理对策。研究发现,“单兵突进”的征地拆迁政策、“效力渐弱”的种粮补贴政策和“前后矛盾”的地方产业政策都是影响耕地“非粮化”的重要因素。建议从整体性视域出发,采取构建整体性政府行政机制以恢复农田系统、补贴政策由“种粮”向“收粮”转变、强化系统治理以统筹产业发展与耕地保护等治理对策,以有效解决耕地“非粮化”问题。

Rethinking assimilation and ethnicity: the Chinese in Thailand

US theoretical models of assimilation of ethnic groups within a larger culture usually assume a unilinear, unidimensional process, which is simplistic, does not account for the persistence of ethnicity, and oversimplifies the process of social change. The argument is advanced that ethnic identity is both primordial and situational (a private sense that is self-maintaining, cumulative, deepening, and self-affirming). Typically, a person has one primary ethnic identity, but where ethnic boundaries overlap, there is instrumental identity. Chinese in Thailand mostly adopt Thai values, speak the Thai language, go to Thai schools, join Thai associations, and celebrate Thai religious festivals. Their secondary identity as Chinese is integrated into their associations with other Chinese and in the home through the use of the Chinese language. Their Chinese identity appears also in ancestor worship. There are symbiotic relationships between native Thais and Chinese Thais along class lines. The Chinese are known to have great financial and economic resources, while the Thais have political and administrative control. These differences with the power elites separate the Chinese from the Thais and interfere with assimilation. The power is balanced. If the Chinese gained in political and administrative power, the balance would be upset, and the interests of both groups would be threatened. The view of Whitten and Whitten acknowledges that individuals and groups act to make the best of the situation and are not merely victims of social forces. Actions are maintained and resisted. The important consideration in theory-building is not the terms of assimilation but the terms specifying the conduct of the group as a whole and as individuals in daily social interactions. The theoretical discussion focuses on border crossings, the Skinner view of the Chinese, bilingualism and cultural education, socioeconomic organizations, occupational differences, and religion, tradition, and ethnic identification.     

How Autonomous are Public Corporations in Hong Kong? The Case of the Airport Authority

This article examines the degree of autonomy of Hong Kong’s Airport Authority (AA). Traditionally, airport management in Hong Kong was the responsibility of the government’s Civil Aviation Department. The AA was established in 1995 to manage the new international airport at Chek Lap Kok which opened in 1998. It was expected to run as a commercial enterprise but, because of its strategic importance, there was concern that it should not become an independent empire detached from government control. As a hybrid type of organization, the AA has moved steadily towards full commercialization. The government has also put its privatization on the agenda. Its transformation may have some implications for the redefinition of the future autonomy boundaries of public corporations in Hong Kong.
