运用协整等计量分析方法实证研究广东省技术创新产出及其影响因素和负外部性的关系。实证结果表明,科技使用额对广东省技术创新产出能力的提升具有推动作用;实际外商直接投资水平和环境规制能力对广东省技术创新产出能力的提升具有抑制作用。同时,科技使用额、实际外商直接投资水平、环境规制能力和广东省技术创新产出能力之间不存在显著的格兰杰因果关系;广东省实际外商直接投资水平的变化会引起广东省环境规制能力变化。
Cointegration and other quantitative analysis methods are used to empirically study the relationship between technological innovation output and its influencing factors and negative externalities in Guangdong Province. The empirical results show that the use of technology has a positive effect on the improvement of technological innovation output capacity in Guangdong Province. The actual level of FDI and environmental regulation capacity have an inhibitory effect on the improvement of output of technological innovation in Guangdong Province. At the same time, there is no significant Granger causality between the amount of technology use, actual level of FDI, environmental regulation capacity and Guangdong’s technological innovation output capacity. The change of actual FDI level in Guangdong Province will cause environmental regulation in Guangdong Province Ability changes.
