摘要 我国高新产业和传统产业R&D投入产出具有劳动投入影响大、资本投入为主要途径的基本特点,表明强度越来越大。近年来,我国R&D经费投入呈“S”形变化,用Logistic增长曲线对研发溢出进行拟合,运用R&D经费投入强度的空间矩阵分析若干支柱产业,表明虽然新兴产业发展快,贡献大,但传统产业仍占比高收益大。 R&D input and output in China’s high-tech industries and traditional industries have the basic characteristics,such as large labor input and taking capital investment as the main approach,which indicates that the intensity is increasing.In recent years,R&D expenditure investment in our country have changed in an“S”shape.This paper uses the logistic growth curve to fit the R&D spillovers and the spatial matrix of R&D expenditure intensity to analyze several pillar industries.The results indicate that although the emerging industries are developing fast and contributing a lot,the traditional industry still accounts for a large proportion of high returns.
