以净初级生产力作为生态系统服务的综合测量指标,在经典柯布道格拉斯生产函数的基础上,运用协整与误差修正模型对1986-2010年黑龙江省生态系统服务对区域经济增长的影响进行了分析,并评估了净初级生产力的边际价格。结果表明,黑龙江省生态系统服务对区域经济增长具有明显的促进作用,净初级生产力每提高1%促进真实GDP增长0.0257%;在生态系统服务的影响下,黑龙江省经济系统以每年1.8%的速率将系统波动产生的非均衡状态向长期均衡状态调整,说明生态系统服务在促进经济增长的同时也保障了经济体系的稳定运行;在误差修正模型基础上得到的黑龙江省净初级生产力的边际价格为255.1元/106kgC(以1952年价格为基准),此价格主要受净初级生产力产出弹性的影响。

In order to improve the accuracy and reliability of the ecosystem services assessment and promote the future ecosystem services conservation and sustainability, the way and extent of ecosystem services contributed to the regional economy growth need to be understood. Therefore, in this article net primary production is used as a proxy for ecosystem services, Heilongjiang province is chosen as the empirical study area,and co-integration and error correction models are applied to reveal both the marketed and non-marketed contributions of ecosystem services to the regional economy growth. The results show that ecosystem services in Heilongjiang province had an obvious role in promoting the regional economy growth as one percent increasing in the output of net primary production increases the real GDP by 0.0257% during 1986-2010.Marginal price assessment based on the economic axiom that the price for a factor of production equals its marginal product could reveal the social cost and economic value of ecosystem services and aggregate the marginal price estimation of different scales at one consistent level. The internal relations between ecosystem services and regional economy growth and the marginal price of net primary production this article revealed have strong implication for the ecosystem services utilization and conservation, and provide strong evidence that sustainable management of ecosystem services could be very beneficial.
