GATS is a household survey with a standard protocol and its goals are to measure tobacco use, to assess changes due to policy and to facilitate cross country comparison. China is the largest consumer and producer of tobacco in the world. China was selected as one of 14 countries of high burden of tobacco use, large population, and mostly low income, to conduct the GATS.展开更多

Instead foreign currency claims (largely dollars) build up within domestic financial institutions. And (2) economists – both American and Chinese – mistakenly attribute the surpluses to an undervalued renminbi. To placate the United States, the result is a gradual appreciation of the renminbi against the dollar of 6% or more per year. This predictable appreciation since 2004, and the fall in US interest rates since mid 2007, not only attracts hot money inflows but inhibits private capital outflows from financing China’s huge trade surplus. This one-way bet in the foreign exchange markets can no longer be offset by relatively low interest rates in China compared to the United States, as had been the case in 2005-06. Thus, the People’s Bank of China (PBOC) now must intervene heavily to prevent the renminbi from ratcheting upwards – and so becomes the country’s sole international financial intermediary. Despite massive efforts by the PBOC to sterilize the monetary consequences of the reserve buildup, inflation in China is increasing, with excess liquidity that spills over into the world economy. China has been transformed from a deflationary force on American and European price levels into an inflationary one. Because of the currency mismatch, floating the RMB is neither feasible nor desirable – and a higher RMB would not reduce China’s trade surplus. Instead, monetary control and normal private-sector finance for the trade surplus require a return to a credibly fixed nominal yuan/dollar rate similar to that which existed between 1995 and 2004. But for any newly reset yuan/dollar rate to be credible as a monetary anchor, foreign "China bashing" to get the RMB up must end. Currency stabilization would allow the PBOC to regain monetary control and quash inflation. Only then can the Chinese government take decisive steps to reduce the trade (saving) surplus by tax cuts, increased social expenditures, and higher dividend payouts. But as long as the economy remains overheated, the government hesitates to take these trade-surplus-reduction measures because of their near-term inflationary consequences.展开更多

Model simulations and palaeoclimatic data studies show an evident change in temperature and precipitation over China will occur under conditions of the global warming. Possible scenarios of the future climates are given here for China on the basis of synthesizing model simulations and palaeoclimatic data. Most parts of China will experience an increase in temperature, but the warming may be more remarkable in winter in h1e northern half of the country. Increase in precipitation will be seen in nearly every parts of the eastern China, and it will be larger in North and Northeast China. Impacts of the climate changes on the national tourism are assessed. Regions suitable for tourisin development in terms of climate comfortable index will shift northward. Some scenic spots and toruism facilities will be damaged due to sea level rise and increased rainfall. Some regions will benefit from the dimate change, but the tourism industry as a whole will be negatively affected.展开更多

The differences between regional climate variations and climate jump are the very important features and phenomena in estimating the trend of environmental evolution in the future. Finally, it is pointed out that sensitive zone is an ideal place to study global change. Many evidences show that the response of environmental elements in the sensitive zones to global change events is very obvious, so that much attention should be paid to the study of sensitive zone.展开更多

The global ocean model employed is based upon the ocean general circulation model of the Massachusetts Institute of Technology. A sequential data assimilation scheme within the framework of 3D variational (3DVar) analysis, called multi-grid 3DVar, is implemented in 3D space for retrieving multiple-scale observational information. Assimilated oceanic observations include sea level anomalies (SLAs) from multi-altimeters, sea surface temperatures (SSTs) from remote sensing satellites, and in-situ temperature/salinity profiles. Evaluation showed that compared to the model simulation, the annual mean heat content of the global reanalysis is significantly approaching that of World Ocean Atlas 2009 (WOA09) data. The quality of the global temperature climatology was found to be comparable with the product of Simple Ocean Data Assimilation (SODA), and the major ENSO events were reconstructed. The global and Atlantic meridional overturning circulations showed some similarity as SODA, although significant differences were found to exist. The analysis of temperature and salinity in the current version has relatively larger errors at high latitudes and improvements are ongoing in an updated version. CORA was found to provide a simulation of the subsurface current in the equatorial Pacific with a correlation coefficient beyond about 0.6 compared with the Tropical Atmosphere Ocean (TAO) mooring data. The mean difference of SLAs between altimetry data and CORA was less than 0.1 m in most years.展开更多

Although this pattern is in good agreement with the latitude distribution of the difference of zonal mean rates of precipitation between 4 × CO2 and 1 × CO2 simulated by climate model (Manabe and Wetherald, 1983), more studies are required to understand the linkage between the aridity trend in China and the greenhouse effect.The EOF analysis of the Northern Hemisphere sea level pressure for the season of June to August shows an abrupt change of the time coefficient of its first eigenvector from positive to negative in mid-1920's, indicating an enhancement of the subtropical high over Southeast Asia and the western Pacific after that time. This is an atmospheric circulation pattern that is favorable to the development of dry climate in China.展开更多

From 1842 to 1901, China was forced to sign 29 "unequal treaties", depriving China of much of its sovereignty. (China lost tariff autonomy, consular jurisdiction over foreigners, control over land in concession areas, inland shipping rights, control over foreign troops, and the right to outlaw opium and to tax businesses). These sovereignty losses correlated with China's economy shrinking to about five percent of the world economy by 1949 (Maddison, 2009). Communist China regained full sovereignty in 1949 and, even with a post-Korean War US-led Western blockade; China's planned economy model achieved average GDP per capita growth of 2.8% annually from 1949 to 1973, despite the disasters of the Great Leap Forward and Cultural Revolution (Maddison, 2009, p. 216). Though twice the per capita growth rate of India (1.4%), China's growth was only 35% of Japan's growth rate (eight percent from 1950 to 1973). After Mao's 1976 death, Deng Xiaoping, with the new global political/economic environment, opened China to the global economy, achieving annual per capita growth of more than five percent (Maddison, 2009). China's per capita income increased from USD 200 in 1978 to about USD 5000 in 2012, making China the world's second largest economy. We will explore how China used its post-1949 full sovereignty to combine lessons from China's semi-sovereign past and its domestic experiences (Great Leap Forward and Cultural Revolution) to engage in Western-style market reforms and "China Goes Global" policies. These Chinese reforms were also based on the post-WWII changed international environment and the success of Japan and the Four Tigers in creating "miracle" economies.展开更多

Although this pattern is in good agreement with the latitude distribution of the difference of zonal mean rates of precipitation between 4 × CO2 and 1 × CO2 simulated by climate model (Manabe and Wetherald, 1983), more studies are required to understand the linkage between the aridity trend in China and the greenhouse effect.The EOF analysis of the Northern Hemisphere sea level pressure for the season of June to August shows an abrupt change of the time coefficient of its first eigenvector from positive to negative in mid-1920's, indicating an enhancement of the subtropical high over Southeast Asia and the western Pacific after that time. This is an atmospheric circulation pattern that is favorable to the development of dry climate in China.
文摘Before 1842, China was a major world economic power, about 30% of the world economy. From 1842 to 1901, China was forced to sign 29 "unequal treaties", depriving China of much of its sovereignty. (China lost tariff autonomy, consular jurisdiction over foreigners, control over land in concession areas, inland shipping rights, control over foreign troops, and the right to outlaw opium and to tax businesses). These sovereignty losses correlated with China's economy shrinking to about five percent of the world economy by 1949 (Maddison, 2009). Communist China regained full sovereignty in 1949 and, even with a post-Korean War US-led Western blockade; China's planned economy model achieved average GDP per capita growth of 2.8% annually from 1949 to 1973, despite the disasters of the Great Leap Forward and Cultural Revolution (Maddison, 2009, p. 216). Though twice the per capita growth rate of India (1.4%), China's growth was only 35% of Japan's growth rate (eight percent from 1950 to 1973). After Mao's 1976 death, Deng Xiaoping, with the new global political/economic environment, opened China to the global economy, achieving annual per capita growth of more than five percent (Maddison, 2009). China's per capita income increased from USD 200 in 1978 to about USD 5000 in 2012, making China the world's second largest economy. We will explore how China used its post-1949 full sovereignty to combine lessons from China's semi-sovereign past and its domestic experiences (Great Leap Forward and Cultural Revolution) to engage in Western-style market reforms and "China Goes Global" policies. These Chinese reforms were also based on the post-WWII changed international environment and the success of Japan and the Four Tigers in creating "miracle" economies.
文摘The article briefly introduces the situation of the global mobile communications market,and based on the development status quo of China's mobile communications market,studies the strategy for China Telecom to enter the mobile market,mainly focusing on mo- bile technologies selection,differentiable services,regional strate- gies and price policies.
文摘The climate change prediction in China based on OCU model as well as summary ana-lyses of GFDL, GISS, NCAR, OCU and UKMO models are used for discussing the approaches topredict the response of the forest in China under double concentration of atmospheric carbondioxide after about 2020. The growth, production and distribution boundary of Chinese fir(Cunninghamia lanceolata), the tree composition and their growth in cold temperete Daxingan Moun-tain region, and potential forest zones in China are discussed in this paper as example.
