通过对广东省21个地级市2000—2010年的信息技术和服务业创新水平进行评价比较,发现信息技术和服务业创新水平表现出正相关性和非均衡性发展的现象,呈现出以珠三角为中心的核心—外围空间分布模式。实证结果揭示:广东省各个地区的信息技术和服务业创新之间存在长期均衡和双向格兰杰因果关系,无论在短期还是长期,服务业创新和信息技术之间相互影响的方向均为正,粤北山区的估计系数都较高;信息技术对服务业创新的短期影响力度大于长期均衡影响,而服务业创新对信息技术的短期影响力度比长期均衡影响小。
By comparing and evaluating the innovation level of information technology and service industry in 21 prefecture-level cities of Guangdong province from 2000 to 2010, it is found that the innovation level of information technology and service industry shows a positive correlation and a non-equilibrium development. Triangle - Centered Core - Peripheral Space Distribution Model. The empirical results reveal that there is a long-term equilibrium and two-way Granger causality between the innovation of information technology and service industry in all regions of Guangdong Province. Whether in short-term or long-term, the interaction between service innovation and information technology is positive. The estimated coefficients of mountainous areas in northern Guangdong are all high. The short-term impact of information technology on service innovation is greater than that of long-term equilibrium, while the short-term impact of service innovation on information technology is less than that of long-term equilibrium.
