下营坊花岗斑岩产于燕山台褶带的兴隆—宽城凹褶束内,系燕山期小岩株,属钙碱性系列,具壳幔混源成因,岩石蚀变强烈,并可见孔雀石化。岩石中钾长石有序度高,科长石An=25-35,黑云母均为镁质,副矿物为磁铁矿—榍石—磷灰石型。成矿元素Cu、An与CaO和S显著正相关,与SiO2反相关。K2O与Na2O反相关.K2O/Na2O>1,Fe3+/(Fe3+Fe2+)=0.53,σ<3,(L/Sm)=5.73,(La/Yb)N=21.4,δEu=-0.30。CU和Au丰度高,变化幅度大,并且Cu与深度正相关显著。各种特征均与世界上Cu—Au成矿岩体相符。有关成矿性图解和数理统计分析亦证明下营坊岩体为成矿告体。 相似文献

Organising international supplier relations: An exploratory study of Western purchasing in China 总被引:1,自引:1,他引:1
This paper analyses Western purchasing in China in order to investigate the motives for sourcing, the specific requirements of the area and, in particular, the base and features of supplier relationships. It reports recent experiences of seven companies based in Finland, including two global companies, two units with foreign ownership and three Finnish SMEs. Prevalent in Chinese sourcing are long-term supplier relations, but no partnership relations have been established. The companies build their supplier relations gradually and they all emphasise a long-term viewpoint to Chinese sourcing. Commitment of the Chinese partner is a key challenge, overcoming of which would help companies to avoid and solve, e.g. quality problems. The study shows that, for the Western supply personnel, key competences and tools for bridging the psychic distance are social skills and interest in the Chinese culture. 相似文献

The purpose of this paper is to explain the pattern of regional unemployment in transitional China. A model is developed to explore how urban unemployment in the provinces is influenced by peasants' wages, formal sector wages, and the size of the formal sector. Evidence from panel data suggests that a significant indicator of high unemployment rates is greater Urban–Rural Income Inequality within the province. The hypothesis is that the urban–rural income gap produces migration, and more rural migrants substitute for urban workers, causing further urban unemployment.Since the economic reforms began in 1978, the non-state owned enterprises have been carrying an increasing weight in the economy, and they have contributed significantly to the rapid economic growth of China. Empirical evidence shows that economic reforms have reduced unemployment. The provinces that are still heavily dependent on the state sector are therefore more likely to experience higher unemployment. 相似文献

This paper proposes a spatial structural decomposition analysis to measure the effects of the changes in intra- and inter-country linkages on the embodied energy demand in the concerned country. For the empirical analysis, we have used the China- Japan inter-country input–output tables for 1985 and 1990, expressed in constant prices of 1990. The empirical results reveal that (1) at least for the period between 1985 and 1990, the effects of the non-competitive input structural changes in China on the primary energy requirements of Japan were negligible, and (2) the contribution of the Japanese final demand shifts on the total change in Chinese primary energy demand was 40 times larger than that of the Chinese final demand shifts on the primary energy requirements of Japan. The Japanese policy makers should concentrate on the energy impacts of the changes in the domestic production structure rather than the changes in the Chinese production structure. 相似文献

This paper looks at the economic rise of China and its impacts and implications for the Association of South-East Asian Nations (ASEAN) region. The issues of complementarities and competitiveness of ASEAN and China in trade and investment and the opportunities and challenges arising from China's emergence and the ASEAN-China Free Trade Area are discussed. The message from China's emergence is clear and strong; it is that size does matter. To increase ASEAN competitiveness, the paper highlights the need for a deeper and more rapid economic integration of ASEAN in order to exploit scale economies. The important role of Japan in this process is highlighted. Finally the issue of ASEAN economic diversity is discussed. It is suggested that while ASEAN is fairly diverse, this should not be a critical stumbling block to a more rapid economic integration of ASEAN. 相似文献

Government as a discriminating monopolist in the financial market: the case of China 总被引:2,自引:0,他引:2
Roger H. GordonWei Li 《Journal of public economics》2003,87(2):283-312
We show that the many unusual features of China’s financial markets are consistent with a government choosing regulations to maximize a standard type of social welfare function. Under certain conditions, these regulations are equivalent to imposing explicit taxes on business and interest income, yet should be much easier to enforce. The observed implicit tax rates are broadly in line with those observed in other countries. The theory also forecasts, however, that China will face increasing incentives over time to shift to explicit taxes. 相似文献
