摘 要:地理加权回归适用于局部关系的回归研究,可以更好地反映空间数据的空间异质性。利用GWR模型并结合相关理论分析我国生产性服务业发展的影响因素发现:人力资本对生产性服务业的发展呈正相关作用,而在2011年的中西部地区其的贡献相对较低;创新能力对生产性服务业发展的贡献为正,但存在减小的趋势;城市化水平对生产性服务业的影响变化较大,由2005年和2008年的负相关转变为2011年的正相关;工业发展水平对生产性服务业的贡献为正,高值区存在由东向西转移的趋势;对外开放水平与生产性服务业呈明显的负相关性;市场规模对生产性服务业发展的贡献为正,且有增强的趋势。

Abstract: Geographically weighted regression is suitable for the local relationship regression study, can better reflect the spatial heterogeneity of the spatial data. Using the GWR model and combined with related theoretical analysis the influence factors of producer services development in our country, found that human capital positively correlated to the development of producer services, and in 2011 the central and western regions of the contribution is relatively low; Innovation ability with a positive contribution to the development of producer services, but decreases; Urbanization level's influence on the producer services vary considerably, from 2005 in 2008 and the negative correlation to positive correlation in 2011; Industrial development level of producer services is positive, the contribution of the high value area is shifting from east to west trend; Opening up to the level and the producer services are significant negative correlation; The size of the market with a positive contribution to the development of producer services, and has a tendency to increase.
Key words: producer services; GWR; influence factor
引 言
20世纪80年代以来,全球产业结构开始呈现出“工业型经济”向“服务型经济”转型的趋势,生产性服务业逐步取代制造业成为西方都市区经济发展的核心动力和创新源泉[1]。在我国,发展具有更大带动作用和科技含量的生产性服务业成为实现产业结构优化升级和经济发展方式转变的重要措施。
国外学者对生产性服务业的研究开始于20世纪70年代[2],主要集中在对生产性服务业集聚的动因、集聚区模式和集聚形态动态演化等问题的初步探讨方法。Dniels(1985)[3]指出,传统和威望等人为因素以及劳动力等经济因素仍然会促使生产性服务业的办公场所向大城市的中央商务区集聚。……
