| 中文摘要: |
| 文章采用区位商方法测算中国各省域高技术产业的集聚度，并在此基础上构建面板门槛模型，检验研发投入对高技术产业知识产出和经济效益是否存在门槛效应。结果表明，高技术产业集聚水平不高但呈现出逐年上升的趋势，且区域之间差异较大，存在东高西低的现象；研发投入是推动高技术产业技术创新的重要动力，对知识产出和经济效益分别存在显著的单门槛和双门槛效应，跨越门槛值后，研发投入对知识产出的促进作用增强，而对经济效益的抑制作用减弱。因此，应当加大研发资金投入力度，鼓励高技术产业大规模集群式发展。 |
| 英文摘要: |
| In this paper, the location quotient method is applied to measure the agglomeration degree of provincial high-tech industries in China. On this basis, a panel threshold model is constructed to test whether R&D investment has a threshold effect on the knowledge output and economic benefits in these industries. The results show that the level of high-tech industrial agglomeration is not high,but it shows a rising trend year by year, and there is a great difference between regions,with higher level in the east and lower in the West;R&D investment is an important driving force to promote the technological innovation for high-tech industries, which produces significant single threshold and double threshold effects on knowledge output and economic benefits respectively. After crossing the threshold value,the promotion effect on knowledge output is strengthened, while the inhibition effect on economic benefits is weakened. Therefore,R&D investment should be further improved, so as to encourage large-scale cluster development of high-tech industries. |
