摘要
文章基于跨省面板数据构建动态空间面板杜宾模型,采用空间偏微分法深入估计了电话与互联网两类通讯基础设施对经济增长的直接效应与空间溢出效应,同时进行了区域异质性分析。实证发现:电话普及率与互联网普及率对经济增长均有不显著的正向直接效应,前者有不显著的正向空间溢出效应,后者则有显著的负向空间溢出效应,而二者的交互项在长期与短期均表现出显著的正向直接效应与空间溢出效应,且长期表现均优于短期,两个时期发挥的总效应均主要来自空间溢出效应。此外,东部地区二者的交互项有显著的负向空间溢出效应,而中西部地区二者的交互项则有正向空间溢出效应。为此,今后应建立电话与互联网两类通讯基础设施的动态耦合协同机制,提高区域联动性与整合度,充分发挥其对地区经济增长的促进效应。
Based on the cross-provincial panel data, this paper constructs a dynamic spatial panel Dobbin model, makes an empirical analysis on the spatial spillover effect of telephone and Internet communication infrastructure on economic growth,deeply estimates the direct effect and spatial spillover effect of communication infrastructure on economic growth by using the spatial partial differential method, and analyzes the regional heterogeneity. The empirical results show that telephone penetration and Internet penetration have no significant positive direct effect. The former has no significant positive spatial spillover effect,while the latter has significant negative spatial spillover effect. The interaction terms of the two show significant positive direct effect and spatial spillover effect in the long-term and short-term, and the long-term performance is better than that in the short-term. The total effect of the two periods mainly comes from the spatial spillover effect. In addition, the interaction term of the eastern region has a significant negative spatial spillover effect, while the interaction term of the central and western regions has a positive spatial spillover effect. Therefore, it is of necessity to establish a dynamic coupling and coordination mechanism between telephone and Internet communication infrastructure, improve regional linkage and integration, and give full play to its promoting effect on regional economic growth.
