摘　　要：本文采用DEA-SBM方法对我国工业企业产品创新效率进行了测评。研究表明,由于纯技术效率水平低下,目前我国各省市工业企业产品创新效率普遍较低。总体而言,东部地区工业企业产品创新呈现规模收益递减趋势,产品创新投入相对过剩;西部地区呈现规模收益递增趋势。技术效率和规模效应的区域差异并不明显,纯技术效率在不同地区间的差异显著。研究结论为我国区域工业企业产品创新提供政策启示。The product innovation efficiency of industrial enterprises in China is evaluated using DEA-SBM method. The research shows that product innovation efficiency of industrial enterprises is generally low in China＇ s provinces and cities because of the low level of pure technical efficiency. Overall,the product innovation in eastern industrial enterprises shows trends of diminishing return to scale,the investment of product innovation is relative surplus; the product innovation in western area shows trends of increasing return to scale. There is no obvious regional differences on technical efficiency and scale effect,and the difference of pure technical efficiency among different regions is significant. The research conclusion provides policy implications for the product innovation of regional industrial enterprises in china.
