This study uses the current laws and regulations of Mainland China as the researching objectives trying to figure out some possible methods to be the references for those who are interested in investing into Chinese market in the near future. Although PRC has agreed to release trading right after joined WTO, the detailed regulations are not very clear yet. For those foreign traders may uncarefully disobey China¡¦s laws due to misunderstand the laws or just believe people¡¦s words in the market. This may put themselves in a high risk situation. After analyzes the laws, this study designs a suitable open questionnaire to have in-depth interviews with some high level managers currently working in Mainland China to explore Taiwanese SME¡¦s activities. On the method of qualitative research, we have to concern on three creteria: A. correct description, B.criticism and analysis, C. discovery¡CThis study found: information is difficult to be collected in China market¡Bthe credit is poor of your business objects¡Bchannels and sources of goods are difficult to control and difficulty to collect money. These problems will increase the transaction cost. While to build Guangxi or relationship and establish commercial friendship in Chinese market will help you to reduce the transaction cost. China market is a rapid growing but also high competitive market. To find a proper entry model is very important topic.

This study emanates from the worldwide issue of climate change, as well as the need for all nations to make an effort to reduce their carbon emissions and move towards greener economies. It delves into South Africa's current command-and-control environmental enforcement regime and highlights the pitfalls that allow major air polluters to avoid sanction of any form in many instances. This poor environmental enforcement and compliance effectively means that South Africa is unlikely to be capable of meeting targets set under international agreements. The study confirms that environmental enforcement is inadequately addressed in South Africa. This is attributable to the inherent shortcomings of command-and-control approaches, including that they are inflexible and offer few incentives for firms to modify behaviour to reduce emissions. Poor enforcement of environmental legislation results in negative externalities caused by air pollution being borne by people who did not create such pollution. The study therefore advocates the use of market-based mechanisms as an alternative to traditional command-and-control approaches to environmental enforcement. In light of the South African government's recent publication of the Draft Carbon Tax Bill, carbon taxes as a subset of market-based environmental enforcement mechanisms have the potential to better enforce the polluter pays principle. Mexico, arguably the most forward-thinking developing nation in terms of climate change mitigation, has taken numerous steps towards meeting international commitments, including the implementation of a carbon tax. While South Africa's proposed carbon tax does differ from Mexico's in some respects, the basic premise remains the same and some comparisons can be made in this regard, with accompanying lessons to be learned. Such lessons include that it is imperative that the carbon tax must be set at a high enough rate to meet international commitments whilst at the same time avoiding adverse economic effects, maintaining social welfare and stabilising economic output levels. The proposed carbon tax, while unable to achieve this on its own, is a good place to start and should be utilised in conjunction with the Draft Climate Change Bill to effectively and efficaciously bring about the required change. The proposed carbon tax undoubtedly has the potential to better hold major air polluters responsible for their CO2 and other GHG emissions. / Private Law / LL. M.
