采用1998—2012年的数据,在空间向量自回归参数模型(Sp VAR)的基础上,构建了半参数空间向量自回归模型(SSp VAR),并以京津冀地区为例,研究了资本积累、经济增长与能源碳排放之间的空间冲击效应。研究结果表明:R&D资本与经济增长、人力资本、物资资本和能源碳排放均存在明显的非线性关系;在北京地区各经济变量的冲击下,京津冀地区的资本、经济和能源碳排放均表现出不同的响应模式。
Through using the data from 1998 to 2012, the semi- parameter spatial vector autoregression model(SSp VAR) is built upon the Sp VAR model. Meanwhile, the spatial impacts of China's capital accumulation, economy growth and CO_2 emission from fossil energy is researched by using Beijing-Tianjin-Hebei region as an example. The results indicate: Nonlinear relationship exists between the RD capital, physical capital, human capital and CO_2 emission from fossil energy consumption, significantly. Under the impacts of endogenous variables from Beijing, the responses of capital, economy and fossil energy carbon emissions in Beijing, Tianjin and Hebei region present different response patterns.
