Based on measure volatility of telecommunications investment in fixed assets,according to the statistical data of telecommunications investment in fixed assets and telecom consumption from 1979 to 2007,this paper analyzes the relativity of telecommunications investment in fixed assets and telecom consumption by using method such as cointegration test and Finite Distributed Lag(FDL) Model.

According to the real pollution state of multi sewage for Huizhou reach of the East River,and measuring data of hydrology and water quality,a multi group distributed lag model for the reach is established.

The problem of determining the lag length arises when a times\|series polynomial distributed lags model(PDLS) is built for economic phenomena.

A corrected auto-regressive distributed lag model was also developed to find the causality of power plants construction volatility with total electricity consumption.

This paper makes a positive analysis of the relation of revenue increase and economic growth in Guangxi province applying regression model, auto-regressive and dynamic distributed lag models.

Objective To investigate the distributed-lag effect of red meat consumption on the incidence of colon cancer by establishing distributed lag model in Beijing urban area.
