【Abstract】 Scientific forecast was of great importance to the economic phenomenon research and economic decision-making. Therefore,the research on economic forecast theory and method was always a focus topic.By combining the grey model,least square method,and topological model,an improved grey algorithm for forecasting was proposed.Using this new algorithm,the paper forecasts the tendency of average energy sources consumption per person in our country and draws the conclusions that the new algorithm is more accurate.It is proved the new algorithm is more accurate.更多还原
