In this paper, the technology of features and object-oriented method, a spatial-temporal data model is proposed, which can be applied in the large information system engineering like the ＂Digital Ocean＂, and this paper discusses the application of spatial data model, marine three-dimensional raster data model and relation data model in the building of Data Warehouse in ＂China Digital Ocean＂, and concludes the merits of these models.展开更多

Secondly, it summarizes the several features and the move trends of China narrow and broad money multipliers and their structure factors. Thirdly, the paper empirically analyzes how and what degree the each structure factor affects China narrow and broad money multipliers holding everything else constant. At last two important conclusions are got, that is, the required reserve ratio is the most associated with China money multipliers and the saving deposit ratio is more associated with that, the required reserve ratio and the interest rates can be used as the ways of affecting money aggregate by the People＇s Bank of China.展开更多
