英文摘要：

The evolution of the demographic structure of major developed countries shows some distinct characteristics. Firstly, the population age structure faces rapid aging;secondly, the population education structure keeps younger and better educated;thirdly, the population industry structure is increasingly service-oriented and high-end oriented;and finally, population migration favors young and skilled immigrants. Experience and enlightenment can be drawn for China from these developed countries in coping with demographic changes for the improvement of national competitiveness. These include a timely adjustment of industrial structure to optimize population structure, an increased admission of skilled immigrants to keep the population younger and high-qualified, an improvement of the human capital investment system to achieve a steady rise of population quality, and an active response to aging pop- ulation to sustain lone-term balanced population development.
