We find that FDI plays a different role in the development of different areas and industries through a comparison with state-controlled industrial enterprises in China. More establishments of smaller foreign funded enterprises and less foreign capital with a high level of management should promote the competition to stimulate manufacturing growth in eastern area, while fewer establishments of foreign funded enterprises with a large capital should make a great stimulus to the western manufacturing development. Both foreign capital and the establishment of foreign industrial enterprises have a great effect on the whole manufacturing sector by industry.展开更多

However, most previous studies focused on individual glaciers and/or decentralized glacial basins. Moreover, a majority of these studies were published only in Chinese, which limited their usefulness at the international level. With this in mind, the authors reviewed the previous studies to create an overview of glacial changes in the Chinese Tianshan Mountains over the last five decades and discussed the effects of glacial changes on water resources. In response to climate change, glaciers in the Tianshan Mountains are shrinking rapidly and are ca. 20% smaller on average in the past five decades. Overall, the area reduction of glacial basins in the central part of the Chinese Tianshan Mountains is larger than that in the eastern and western parts. The spatial differentiation in glacial changes are caused by both differences in regional climate and in glacial factors. The effects of glacial changes on water resources vary in different river basins due to the differences in glacier distribution, characteristics of glacial change and proportion of the glacier meltwater in river runoff.展开更多

These records were used to calculate Q0 (Q at 1Hz) and η values of Lg coda from each station by the stack spectral ratio (SSR) method. Then the tomography method was applied to obtaining lateral variation of Q0 and η values in Chinese mainland and adjacent regions. The result indicates that Q0 value varies between 150 and 600 in the studied areas. Yunnan, southwest Sichuan, and northwest Myanmar show the lowest Q0 value (Q0〈240) and the crust of these regions is characterized by complicated crack and strong hydrothermal activity. The highest Q0 value (Qo〉510) exists in the border of southern Mongolia, Alxa and Ordos block. The η value varies between 0.45 and 0.75 in Chinese mainland and its adjacent regions.展开更多

In this paper, we perform an analysis of surface air temperature in a region of China using a decomposition method in time series analysis. Applications to the National Centers for Environmental Prediction/the National Center for Atmospheric Research (NCEP/NCAR) Collaborative Reanalysis data in this region of China are discussed. The main finding was that the surface air temperature trend estimated for January 1948 to February 2006 was not statistically significant at 0.5904℃ (100 yr)^-1. Forecasting aspects are also considered.展开更多
