However, activities in a fast-growing economy significantly impact the supply and demand of these watershed services. To mitigate these impacts, the concept of payment for environmental and ecosystem services from water-sheds has emerged in global academic and policy circles. The governments and academic communities in China have increas-ingly described payments for ecological services from watersheds with the concept of watershed eco-compensation as it is urgent to protect watershed ecosystems. Watershed eco-compensation has proved to be one of the most economically effective means of solving environmental problems of watersheds to be adopted by the Chinese government. This paper presents an objective analysis of the Chinese market for watershed ecosystem services, including supply and demand for the services. It also summarizes Chinese policies on watershed eco-compensation, including relevant laws and regulations and fiscal policies. In addition, it presents a re-view of Chinese practices in watershed eco-compensation, in-cluding the analysis of an ecological construction project in West-ern China, inter-provincial watershed eco-compensation practices and plans, and payment for ecological services at the provincial and small watershed levels. Finally, it summarizes the key com-ponents of the process of payment in Chinese watershed eco-compensation. This discussion forms the basis of concluding suggestions for ecosystem services compensation and ecological protection in the large scale river basin.展开更多

Five fibre feedstuffs--palm kernel cake (PKC), wheat offal (WO), corn bran (CB), rice bran (RB) and brewers' dried grain (BDG) were used at 25% in each of the five experimental diets that were formulated in this study. Twenty weaner pigs (12.75 ± 0.6 kg) were used for the growth study while 15 pigs (14.95 ± 0.57 kg) were used for the digestibility study. The design of the experiment was completely randomized. The results of the study showed that the performance of the experimental animals were significantly influenced (P 〈 0.05) by the dietary treatments. The apparent digestibility of the crude protein, crude fiber and ether extract showed significant differences (P 〈 0.05) while there was no significant difference (P 〉 0.05) in the apparent digestibility of their dry matter, ash and nitrogen free extract. The diet that contained WO had the best growth response and apparent nutrient digestibility. Results of economics of production also showed that diet with WO gave the best (P 〈 0.05) value in feed cost/'kg gain and net profit/animal. It can be concluded from this study that although all the animals fed the different fibre feedstuffs performed satisfactorily on all the parameters monitored, but for optimum growth, apparent nutrients digestibility and economics of production. WO should be used as a fibre feedstuff in the diets of weaning/growing pigs in the tropics.展开更多

Therefore, municipalities must develop local programs for prevention and integrated management of MSW based on the data of MSW generation; however, these are scarce and diffuse. It is known that the MSW generation is affected by many factors, including life level. Given the importance of having reliable data, the objective of this study was to determine the per capita MSW generation of a small urban locality in the state of Veracruz and test whether there were significant statistic differences of per capita M SW generation among the life levels. The households were randomly sampled according to the Mexican standard of reference and were classified as popular, middle and residential. The per capita MSW generation determined was 0.355 kg·inhab^-1.day^-1. This value was lower than the value estimated by the national reference, suggesting that it might be overestimated and consequently lead to errors in estimating installations costs for the MSW treatment. The result of the experimental design revealed that there were significant statistic differences in the per capita MSW generation among the three socioeconomic strata. This study will allow the municipality to establish better strategies within the municipal program and differential rate for the provision of public clean service and it also provides a solid basis for future research under similar conditions.展开更多

This article briefly summarizes economists defined the government intervention and market regulation in the history of economic. Since the founding of New China, it elaborated to defining process of government intervention and market regulation in the development China' s economic. Under the new situation, it proposed government intervention should combine market regulation to achieve sound and fast development of economic. Market regulation in the development of vocational education for the economic development is the goal of training practical talents of vocational education. This objective requires that vocational education must work closely with the needs of economics' development and service for the economics' development. Under the system of planned economy, contraction between supply of talent and needs of economic is planning to achieve indirectly through a unified government.展开更多

This paper uses empirical analysis to prove that the service sector has a long-term mechanism to promote employment growth: first, the verification of the Baumol-Fuchs hypothesis shows that the income elasticity of demand for services in China is greater than 1. As the current development of the services is lagging behind, this sector has great development potential. Second, the revised employment equation shows that the employment elasticity of the service sector is much higher than that of the industrial sector, and its employment adhesiveness is stronger as well. The employment of the service sector can not only create more jobs for the national economy, but also help stabilize the job market. The employment pressure in China is mainly caused by migrant workers and college graduates. To solve the employment problems of these two groups, China has to promote the development of traditional services and speed up the upgrading of emerging services at the same time, and should neglect neither. This paper provides recommendations accordingly.展开更多

Traditional research into legal doctrine is unfavorable to the creative exertion of international jurisprudence, and the research methods of social sciences are playing an increasingly important role in the methodological innovation of international law. From the perspective of promotion of the international rule of law, the study of international law needs to deep research a State's motives, cause and innate logic in observing international aw, and law and economics can show its capability in this field. For the international rule of law, basic research needs to be carried about such social surroundings as where the rules are produced and applied and exerting influences. The research method of the sociology of law exactly hits the point. The application of empirical and experimental research methods offers a beforehand "rehearsal" chance for the process of the rule of law to grasp the pros and cons in the planning andpractice of the rule of law. The cooperation between the research methods of social science and the traditional research method of international law can reasonably interpret the phenomena of international relations and promote the international rule of law.展开更多

Furthermore, this paper specifies a nonlinear threshold cointegration model to reveals a nonlinear relationship between the urban-rural income gap and real economic growth over a long period since reform and opening up in China. Our results show that the regime switch of the long-term nonlinear threshold relationship takes place at the 0.100 (threshold value) of the Theil index. From 1978 to 1991, the long-term effect of the urban- rural income disparity on China's economic growth was positive; between 1992 and 1999, there was a smooth transition to a negative effect; and from 1999 on, the negative effect has been increasing year by year. Income disparity now has the effect of retarding China's real economic growth.展开更多

In this paper, we propose a new observable criterion called Marshallian deviation. It can be used to measure the distance of a transaction path deviating from the Marshallian path mathematically, and to answer the question why buyers with high values will trade with sellers with low costs in advance in some types of DA but not in others. Furthermore, three factors influencing the Marshallian deviations both in the CDA and in the PDA are also studied. They are respectively the strategic algorithm, the transaction duration and the number of traders. A few interesting findings are presented.展开更多
