中国工业生产率区域差异持续扩大,导致区域经济难以均衡增长。在此背景下,估算了中国31个省市的工业生产率偏移的资本产出差异项和劳动产出差异项,发现各省市的工业技术特征具有明显的空间依赖性。分别使用似不相关估计(SUR)和空间面板的空间滞后模型(SLM)以及空间误差模型(SEM),检验了我国R&D投入对工业生产率的作用机制。研究结果表明,我国R&D投入更容易引致资本深化的劳动偏向型技术创新,劳动资源丰富的地区不能通过R&D投入取得竞争优势;而资本市场发达的地区从R&D投入中更容易获得技术优势。
Regional differences in China’s industrial productivity have continued to expand, which has caused regional economies to struggle to achieve balanced growth. In this context, the differences in capital output disparities and labor output disparities of industrial productivity shifts in 31 provinces and cities in China were estimated, and it was found that the industrial technology characteristics of each province and city have significant spatial dependence. The spatially lagged model (SLM) and spatial error model (SEM), which are irrelevant estimations (SUR) and space panels, are used to test the mechanism of R&D investment in China on industrial productivity. The research results show that China’s R&D investment is more likely to lead to capital-intensive labor-biased technology innovation, and regions with abundant labor resources cannot obtain competitive advantage through R&D investment; and regions with developed capital markets are more likely to obtain technological advantages from R&D investment.
