本文以1999年～2005年黑龙江省R&D投入强度作为原始数据,采用灰预测理论建立数列灰预测GM(1,1)模型,对黑龙江省2006年和2007年的R&D投入强度进行预测并得出了预测结果,黑龙江省2006年的R&D投入强度为0.9963,2007年为1.1121,经检验模型预测精度高达95.38%,拟合度很好。 In this paper, the investment intensity of R & D in Heilongjiang Province from 1999 to 2005 was taken as the raw data. The gray forecasting theory was used to establish the gray forecasting model of GM (1,1). The forecast of investment intensity of R & D in Heilongjiang Province in 2006 and 2007 was made. As a result, the input intensity of R & D in Heilongjiang Province was 0.9963 in 2006 and 1.1121 in 2007, and the prediction accuracy of the tested model was as high as 95.38%. The fitting degree was very good.
