摘　　要：把专利间的引用关系看作技术扩散,并将其引入Bass扩散模型,构建含有技术扩散影响因素的改进模型。利用普瑞斯的销售数据和丰田公司被引专利数据,对原始模型及改进模型作了非线性最小二乘法估计。结果表明,技术扩散能够影响消费者购买新产品的愿望,改进模型对HEV扩散的拟合度优于原始模型。It takes the reference relationship among the patents as technology diffusion and introduces it in the Bass diffusion model to build a refined model containing the factors contributed by technology diffusion.Sales data of PRIUS and patent data cited by Toyota are used to estimate the original model and the refined model in the method of nonlinear least squares.The results show that technology diffusion can influence the consumers to buy new products,refined model is better than the original model in degree of fitting of HEV diffusion model.
