The main conclusions are: 1) The regional disparity of economic development in China, including the inter-provincial disparity, inter-regional disparity and intra-regional disparity, has existed for many years. Theil index by the comparative price has revealed the true trend for comparative disparity of regional economic development from 1952 to 2000. 2) Decomposition of Theil index indicates that the dynamic trend of comparative inter-provincial disparity in the coastal region is in line with dynamic trend of inter-provincial disparity in the whole China. 3) The R/S analysis results tell us that during 1966-1978, the Hurst exponent H=0.504 approximate to 0.5, which indicates that in that period the evolution of comparative inter-provincial disparity of economic development showed a random characteristic, and in the other periods, i.e. 1952-1965, 1979-1990 and 1991-2000, the Hurst exponent H>0.5, which indicates that in those periods the evolution of the comparative inter-provincial disparity of economic development in China had a long-enduring characteristic. 4) By using wavelet analysis at different time scale, we arrived at a conclusion that the evolutionary process of the disparity of economic development of China is not a simple inverted U shape but a compound of several U shapes. The result tells us that the evolutionary plot of inter-provincial disparity in China follows the inverted U on the whole at the higher scale, 24 ( 16 years). That is to say, the disparity tends to rise in the first stage of economic development, and fall slowly over the peak in the second stage of economic development. However, if we shorten the time scale to 23 ( 8 years), then a link of several U shapes will appear.展开更多

A large number of information ideas have gradually entered people's lives, bringing a lot of changes to people's lives and work, improving work efficiency and contributing to the country's economic development. Among them, the promotion of information technology has a strong role in promoting enterprises in different industries, especially in human resources management, but also has played its own potential. In such an environment, if you want to further improve the comprehensive economic benefits of the enterprise, you should start from the cultural level of the enterprise, build a positive energy enterprise culture suitable for your own development, and bring new development and progress impetus to the employees in the enterprise, so as to realize all-round human resource management.展开更多

The cause of such a behavior was theoreticallyinvestigated in this paper. The calculation of geostrophic current in this region indicates thatthere are relatively strong meridional geostrophic currents in this region even though the zonalcurrent is dominant in most seasons. Using a 2. 5-layer reduced-gravity model, ba-roclinicinstability of non-zonal current was discussed. It is found that at the western side of STCC thevertical shear of the meridional geostrophic current will be in favor of the ba-roclinicinstability, but at its eastern side it will suppress ba-roclinic instability, thus causing thegrowth of eddies over the western side much faster than that over the eastern side.展开更多
