摘 要: 文章采用二级CES生产函数来分析江苏企业的实际R&D数据,研究出口企业R&D贡献是否不同于非出口的企业,出口和非出口企业的R&D贡献是否会由于产业、地区、企业规模和类型的不同出现差异。通过分析发现:出口企业的R&D投入产出贡献明显高于非出口企业;某些产业的非R&D投入产出贡献大于R&D投入产出贡献;R&D资本投入产出贡献大于R&D劳动投入产出贡献。 With two - level CES production function model, the paper analyzes Jiangsu enterprises' R&D data, and studies whether the R&D contribution of export enterprises is different from that of non - export enterprises and whether the R&D contri- bution of the export or non - export enterprises varies due to the difference of production, area, firm scale and category. The study result shows that the export enterprises' R&D input - output contribution is significantly higher than that of the non - export enterprises, that the non - R&D input - output contribution i~ greater than the R&D input - output contribution for some indus- tries, and that the R&D capital input - output contribution is greater than the R&D labor input - output contribution.
