【摘要】 为了提高农村电网投资效益评估结果的客观性和完整性,基于数据包络分析理论,构建了计及地理空间信息的农村电网投资效益评估指标体系和后评估模型,通过投资效益值、投资冗余度、规模收益增减趋势等指标,客观反映了被评估地区电网的投资效益及其在样本数据集中的效益排序。以是否考虑地理空间信息对于电网投资效益影响的两组指标体系的评估结果为例,证明了本评估方法的有效性、实用性及合理性。更多还原

【Abstract】 In order to improve the objectivity and integrity of rural power grid investment benefit evaluation results,based on data envelopment analysis theory,this paper constructs the rural power grid investment benefit post-evaluation index system and model considering geospatial information.Through the value of investment benefit,investment redundancy and the increasing or decreasing trend of returns to scale,it objectively reflects the investment benefit of the evaluated regional power grid and the benefit order in the sample data set.Considering whether the geospatial information has impact on the power grid investment benefit,this paper proves the availability,practicality and rationality of the evaluation method by comparing the calculation results based on the two groups of evaluation index systems.更多还原
