The concentration of HKDI in the southern China and the coast has has replace by the trend of moving northwards and iulandwards after 1989. But in terms of tnanofacturing sectors this trend has not clearly appeared until now. Those changing Patterns are dearly related to the behaviour of Hong Kong industrial investors.The survey results suggest that 'enjoying lower production cost' is the most important motive for thed investment in China. In consequece, 'close to Hong Kong','cheqper labour' and 'favourable policy' are major factors for determining the investment locations. This behaviour, together with the lack of comparison study in location selection among most investors, explains that Guangdong absorbed most Hong Kong investment in the 1980s. As the production costs have been increasing in Guangdong, are companies have started to invest in non-Guangdong locations since the end of the 1980s. From the mental map of Hong Kong investors, however, only some of the non-Guangdong locations are practically attractive.展开更多

For this launch, ZTE partnered with China Mobile Hong Kong. Grand X LTE (T82) is the company's first single-chip LTE smartphone. It has a 1.5 GHz dual-core CPU based on advanced 28 nm technology. Compared to most phones on the market, the single-chip model is faster and more energy efficient. T82 has a 4.3-inch qHD screen, which provides exceptional HD quality. The phone has an 8 mp rear camera that supports 1080p HD video shooting and playback. The camera module with enhanced flash captures the sharpest images during the day and night. The front camera supports 720p HD video calls. T82 is also WiFi enabled and uses Android 4.0. The maximum download rate is 100 Mbps, and users have access to more than 600,000 Android applications to download. T82 also has a unique buttonless design that resembles a mini tablet.展开更多

Results show that, over the past 124 years, the extreme daily minimum and maximum temperatures, as well as the length of the warm spell in Hong Kong, exhibit statistically significant long-term rising trends, while the length of the cold spell shows a statistically significant decreasing trend. The time-dependent return period analysis also indicated that the return period for daily minimum temperature at 4°C or lower lengthened considerably from 6 years in 1900 to over 150 years in 2000, while the return periods for daily maximum temperature reaching 35°C or above shortened drastically from 32 years in 1900 to 4.5 years in 2000. Past trends in extreme temperatures from selected weather stations in southern China from 1951-2004 were also assessed. Over 70% of the stations studied yielded a statistically significant rising trend in extreme daily minimum temperature, while the trend for extreme maximum temperatures was found to vary, with no significant trend established for the majority of stations.展开更多

They are the largest suppliers to the United States, which is the largest importing market in the world. In this research, export performances of the three areas to the United States are investigated. Analyses indicate that since the 1980s, textile and apparel exports of Inland in China to the US and its market share grew rapidly, while exports of Hong Kong and Taiwan grew much slower, and their market shares declined. Product prices of the three areas in the US market were generally higher than the market average. Especially for apparel, while export compositions of all three areas somewhat leaned towards the lower end of the market, actual product prices were substantially higher than those in the market.展开更多

To account for the discrepancy in the best track data between agencies, the maximum sustained wind speeds are standardized to the 10-minute average before data analysis. Moreover, a sensitivity assessment based on three different data scenarios is also conducted to study the uncertainty in trend analysis due to the discrepancy in the datasets from various agencies. The results show that, likely modulated by the El Ni?o Southern Oscillation and the Pacific Decadal Oscillation, there exist strong inter-annual and inter-decadal variations in the TC frequency in the SCS and the vicinity of Hong Kong.For the long-term trend, all dataset/scenario combinations depict a decrease in the TC frequency in the SCS and the vicinity of Hong Kong during the study period, but the trend is not statistically significant at 5% level for most of the datasets. As for the TC intensity, the discrepancy between weather agencies remains very substantial even when the difference in the wind speed averaging period is accounted for. The large differences in the available datasets do not allow for a reliable detection of the long-term trend of the TC intensity in the SCS. The study of the TC impacts on Hong Kong reveals that there is no significant trend on the TC-induced extreme rainfall in Hong Kong. The extreme high winds associated with TCs within 500 km range of Hong Kong have no significant trend at Waglan Island(offshore island) while those of the urban station at Kai Tak have a signifi-cant decreasing trend.展开更多

Of these,the Ping Chau Formation in the northwestern New Territories is the youngest known stratum. We perform a detailed study of the volcanic rocks of the Ping Chau Formation utilizing zircon U-Pb dating,with major and trace elements geochemistry. LA-ICP-MS zircon U-Pb data reveal Early Cretaceous age from two volcanic rock samples, with zircon crystallization from magmas at 140.3 ± 0.8 Ma and 139.3 ± 0.9 Ma,respectively. These rocks have high contents of total alkalis(Na_2O + K_2O = 5.58-9.45 wt.%), high-field-strength elements and light rare earth elements, conspicuous negative Eu anomalies, and depletions in Nb, Ta, Ti, Sr, Ba and P. Using this data, in combination with previous studies on the late Mesozoic volcanic belt in Southeast China, we propose that the volcanic rocks of the Ping Chau Formation probably originated from deep melting of the crust in a back-arc extensional setting induced by the subduction of the paleo-Pacific Plate. This formation represents the final stages of Early Cretaceous volcanic activity in Hong Kong, as associated with large-scale lithospheric extension, thinning and magmatism. Our results provide new information that can be used in evaluating the significance of Early Cretaceous volcanism and tectonics in Southeast China.展开更多
