The application of this method to modeling the China＇s adjacent seas shows that the Bohai Sea has a highest peak response frequency （PRF） of 1.52 d^-1; the northern Yellow Sea has a PRF of 1.69 d^-1; the Gyeonggi Bay has a high amplitude gain plateau in the frequency band roughly from 1.7 to 2.7 d^-1; the Yellow Sea （includ- ing the Gyeonggi Bay）, the East China Sea shelf and the Taiwan Strait have a common high amplitude gain band with frequencies around 1.76 to 1.78 d^-1 and are shown to be a system that responds to the open ocean forcing in favor of amplifying the waves with frequencies in this band; the Beibu Gulf, the Gulf of Thailand and the South China Sea deep basin have PRFs of 0.91, 1.01 and 0.98 d^-1 respectively. In addition, the East China Sea has a Poincare mode PRF of 3.91 d^-1. The PRFs of the Bohal Sea, the northern Yellow Sea, the Bei- bu Gulf and the South China Sea can be explained by a classical quarter （half for the Bohai Sea） wavelength resonance theory. The results show that further investigations are needed for the response dynamics of the Yellow Sea-East China Sea-Taiwan Strait system, the East China Sea Poincare mode, the Talwan Strait, and the Gulf of Thailand.展开更多

On the basis of systematic collection of statistical data, this paper gives a quantitative estimation of the wage level of rural migrant workers in China and its evolution following pro market reforms since 1978. Results indicate that over the past 30 years, the nominal monetary wage of migrant workers maintained a 10% average annual increase. Real wage levels adjusted by the consumer price index （CPI） experienced three stages of evolution： initially, migrant workers earned a higher average monetary salary than formal employees, whereas this situation reversed in later stages.展开更多

While it reinforces the global mobility of high-technology staff, it does not actually lead to the cross border flow of general labor, especially low-skill labor in the developing countries. This may create a problem for the developing countries, that is, how to combine international capital, which is expanding incessantly and has strong mobility, with the international labor, which is great in quantity and weak in mobility. China’s accession to WTO in 2001 is an important milestone of China’s reform and opening up. This means that China展开更多
