从广义的创新概念出发,根据经济增长的共协理论方法,把国内生产总值分解为劳动报酬、资本收益和共协利益,建立劳动报酬函数、资本收益函数和共协利益函数,并利用DEA方法测算要素配置效率,从而推导出创新等因素在经济增长中贡献率的测算公式,为"创新驱动型经济增长"提供理论基础和测算方法。建立中国经济增长的实证模型,对创新、投资等因素的贡献率进行分析;并测算和分析中国1978—2012年固定资产投资等边际收益率的演化趋势,论证"投资单边驱动"的不可持续性,进而提出和论述"创新驱动—投资互动"战略,使中国经济进入创新驱动的、结构升级的新型经济状态。
Embarks from the broad concept of innovation, and based on the method of collaborative theory, this paper decomposes the GDP into labor remuneration, capital gain and collaborative interest, and establishes their functions respectively, and then it estimates the factors allocative efficiency by adopting the DEA method, thus to derive the calculation formula for the contribution rate of innovation and other factors to economic growth, and accordingly provide the theoretical basis and calculation method for the 'innovation-driven economic growth'. Besides, this paper establishes an empirical model for China's economic growth, and analyzes the contribution rate of innovation, investment and other factors; and estimates and analyzes the evolutionary trend of the marginal income ratio of fixed-asset investment and etc. from 1978-2012, and then demonstrates the unsustainability of unilateral investment drive, thereby the authors put forward and discuss a strategy for China's economic transformation,i.e. the 'innovation-driven and invesment-supportive' strategies.
