新疆作为丝绸之路经济带核心区,为实现基础设施的互联互通,将更多的资金投入到基础设施建设中。在供给侧改革背景下,投资的效率比规模更重要,因此,有必要对低效率投资进行优化调整。本文运用投入导向型的三阶段方法,实证分析了2005年—2015年新疆15个地州市基础设施的投资绩效及其影响因素。结果表明:新疆基础设施投资效率受规模效率的制约;环境因素和随机因素对投资绩效均有明显的影响。剔除这些影响因素后,大部分地区投资绩效均有所变化;南疆地区基础设施投资效率低于北疆以及全疆平均投资效率;在投资额不变的情况下,通过优化产业结构、加强对外开放度、适当调整政府扶持力度可有效提升基础设施投资效率。
After Xinjiang has been set as the core area of the Silk Road Economic Belt, in the realization of infrastructure interconnection and interworking, place more investments in the infrastructure construction. However, under the background of supply-side reform, the efficiency of investment is more important than the scale, and the low efficiency investment should be optimized. This paper applying input-oriented three-stage DEA approach, analyze infrastructure investment efficiency and its influencing factors in 15 regions and prefectures in Xinjiang from 2005 to 2014. The results show that: the efficiency of Xinjiang infrastructure investment is restricted by the scale efficiency; environmental factors and random factors have obvious influence on the investment performance. Excluding these factors, the investment performance in most areas have been changed; In southern area’s infrastructure investment efficiency is lower than Northern area and whole Xinjiang average investment efficiency; Under the same amount of investment, Xinjiang infrastructure investment efficiency can be effectively improved by optimizing the industrial structure, promoting openness and cooperation level, adjusting government support degree.
