摘　　要：在采用关联度及格兰杰因果关系检验来验证信息产业与三大产业之间的关联性的基础上,建立中性技术进步假设下修正的柯布—道格拉斯生产函数,测量信息产业对河北省三大产业的间接贡献度,结果表明:河北省信息产业与服务业有较强的关联度,并且互为发展的因果关系,但与农业的关联水平较低。河北省发展信息产业应依托产业集聚度,充分发挥信息产业集聚效应,加强信息人才培养。By using the correlativity and Granger casualty tests to test the association of the information industry and the three major industries, the article sets up the modified Cobb-Douglas production function under the neutral technical progress assumption and estimates the indirect contribution of information industry on Hebei＇s three major industries. The results show that： the information industry and service industry in Hebei province have strong correlation degree, and have the causality relationship of the development, but the association level with the agriculture is low. The development of the information industry in Hebei province should rely on industrial concentration degree, give full play to the information industry cluster effect, and strengthen the information personnel training.
