摘要
在深入分析中国R＆D投入现状的基础上,借助柯布—道格拉斯生产函数模型,扩展构建了R＆D投入影响高新技术产业发展的数理分析模型,利用中国31个省份2004—2013年的面板数据,估计了资本素、劳动力素、R＆D投入对中国高新技术产业的产出弹性系数。结果显示：R＆D投入虽然在总量上有了大幅提高,但其占GDP的比重依然还非常低;R＆D活动的地区分布也极不均衡,主集中在东部沿海地区;同时由于产业发展水平的不平衡,导致了R＆D活动分布在产业间有较大的差异。整体而言,R＆D投入对于高新技术产业产值的增加具有较大的贡献,在东部地区更为显著,中西部地区R＆D投入对高新技术产业发展贡献的弹性系数比东部地区的1/2还小。相对于资本素和劳动力投入素而言,R＆D投入对高新技术产业发展的贡献在东部地区最大,在中西部地区最小;而劳动力投入素对高新技术产业发展的贡献始终处于十分重位置,其弹性系数始终保持在0.5~0.7之间。根据以上研究结论,结合中国实际,建议采取以下措施：继续加大高新技术产业R＆D投入力量;进一步提高R＆D投入的经济产出能力;注重产业集聚下三大地区的协同发展;转变政府在高新技术产业发展中的角色等等。
With Cobb - Douglas production function model, using the panel data of 31 provinces in China from 2004 to 2013, estimated the output elasticity of R＆D investment, labor factor, capital elements in China＇s high-tech industry. The results show that R＆D investment has a larger contribution to increasing the output of high-tech industry, More remarkable in the Eastern, Midwestern R＆D investment in high-tech industries contribute to the development of elastic coefficient smaller than 1/2 of the Eastern region. In Midwestern regions, elastic coefficient of R＆D investment contribute to the development of high-tech industries is smaller than 1/2 of the Eastern region. Labor elements is always very important for high-tech industry development, the elastic coefficient is always maintained between 0.5-0.7. Capital elements＇ s contribution to the high-tech industry development is largest in the Midwestern, the smallest in the Eastern, capital elements＇ s contribution in Middle and Western region is 2.7 times and 4.6 times than the Eastern respectively. Finally, according to the conclusions of this study some countermeasures and suggestions were presented.
