通过构建三区域投入产出模型测算了我国长三角、珠三角、环渤海经济区服务业的区域内乘数效应、区域间溢出效应和反馈效应。研究结果表明,环渤海和长三角经济区的服务业区域间溢出和反馈效应比珠三角经济区大,环渤海和长三角经济区的区域间溢出效应高于所受到的溢出效应,而珠三角经济区的区域间溢出效应低于所受到的溢出效应。环渤海与长三角经济区之间的服务溢出频繁,珠三角与环渤海、长三角经济区之间的服务溢出较少。
By constructing the three-region input-output model, the intra-region multiplier effect, inter-region spillover effect and feedback effect of service industries in the Yangtze River Delta, Pearl River Delta and Bohai Economic Rim are calculated. The results show that the service spillover and feedback effects between the Bohai Rim and the Yangtze River Delta are higher than that of the Pearl River Delta Economic Zone and the spillover effect between the Bohai Rim and the Yangtze River Delta Economic Zone is higher than that of the Pearl River Delta The spillover effect in the economic zone is lower than the spillover effect. There is frequent spillover of services between the Bohai Rim and the Yangtze River Delta Economic Zone, with less spillover of services between the Pearl River Delta and the Bohai Rim and the Yangtze River Delta Economic Zone.
