Evaluation research on the innovation efficiency as value-chain framework: Evidence from Jiangsu province

摘要

Based on the value-chain framework, the innovation system was divided into two interactive sub-phases: upstream research and development process and downstream technological commercialization process. By introducing network DEA model, we computed the R&D, the technological commercialization and overall innovation efficiencies for 13 cities of Jiangsu province. The findings were presented as follows. From general prospective, none of innovation R&D efficiency, technological commercialization efficiency or overall innovation efficiency was high. From the trend prospective, recent years the trend of Jiangsu's innovation efficiency and economic cycle showed synchronicity. From the value chain prospective, upstream R&D efficiency did not show relation with downstream technological commercialization efficiency, and showed obvious inconsistencies, and the technological commercialization efficiency played a more important contribution to overall innovation efficiency than R&D efficiency. From the innovation regional prospective, the overall innovation efficiency showed obvious regional distinction, southern Jiangsu ranked first, followed by central Jiangsu and northern Jiangsu. This was the same with the level of economic development.
