京津冀协同发展下保定市建设用地对二三产业贡献的区域差异研究

Study on the Regional Contribution of Building Land Input in Baoding to Secondary & Service Industry

作为京津冀核心城市之一,保定市土地供给与经济需求矛盾尤为突出。本文运用扩展后的柯布—道格拉斯生产(C-D)模型,测度2004-2013年保定市22个县(市)建设用地供给对二三产业的贡献,以期为保定市及各县建设用地科学管理提供依据。研究表明:2004-2013年保定市建设用地对二三产业的贡献值为12.69%,高于劳动力5.40%,低于固定资本78.47%;22个县市建设用地投入对二三产业发展贡献区域差异明显,这种差异主要受经济水平、区位条件、产业结构和资源条件等因素的影响。结论:保定市相关部门应因地制宜制定差异性建设用地供给指标,最大限度发挥有限土地资源产出水平,缓解土地供需矛盾。

As one 6f the core city of the Beijing-Tianjin-Hebei region, the contradiction of land supply and demand in Baoding is especially worrying. We use the improved Cobb-Douglas produc- tion function to carry out this study, analyzes the contribution of building land input in Baoding from the year 2004 to 2013. Results： The average reward of Baoding building land input kept in- creasing from 2004 to 2013 and The volatility of marginal output is large. The contribution of capital stock to Secondary and Service in- dustries is highest, then building land, and the lowest is labor, and the value contributions are 78.47%, 12.69% and 5.40%. Contribu- tion to economic growth of construction land supply varies from county to county in Baoding.
