伴随我国经济社会的高速、多元化发展，环境污染呈现出由单一向复合、由点源向面源蔓延与加重的趋势，当前以“雾霾”为特征的区域性大气污染复合问题严重影响了人民群众的身体健康与生命安全。区域作为生态环境保护的基本单元，是多目标、分阶段统筹大气污染防治的责任主体。从环境生产技术视角分析区域经济活动与大气污染物排放的关系，可以从源头上把握内化到生产过程中的大气污染物排放，为生产行为的改善提供目标、责任、路径，乃至中短期生产行为与生产技术预测。本课题采用环境绩效测度、标杆管理、自组织特征映射神经网络、技术计量学等方法，重点研究环境生产技术约束下，自然减排、管理减排、成本最优与多准则减排目标与减排行为，对环境DEA技术进行分层，构建标杆路径，挖掘影响标杆路径选择的深层诱因及技术递阶规律。从实践上分区域、分类别在现实中搜寻“逐步对标对象”，制定可行“逐步对标方案”，为区域减排能力提升提供决策参考。

Following the rapid and diversified developments of economy and society, environmental pollution has been transformed from point-source to area-source, single to complex forms. At present, the regional and complex air pollutions, such as the haze, have been severely affecting people's health and life safety. As the basic unit of protecting ecological environment, district is the liability subject to control air pollution with multi-target and multi-stage. The relationship between regional economic activities and the emissions of air pollutants can be studied in the framework of environmental production technology, which can describe the joint production of desirable and undesirable outputs (pollutants generated), provide the behavioral objective, burden share and emissions path for improving production activity, and even short and medium term predictions for production activity and environmental production technology. Considering the constraints from environmental production technology, this research combines environmental performance measure, benchmarking management, self-organizing feature map neural network and technometrics to study the natural, managerial, costly and multi-criteria abatement activities and targets, stratifies the environmental DEA technology, establishes stepwise benchmarking path, and explores the impact factors, mechanisms and rules for spanning technology levels. In practice, this research will explore and classify the benchmarks for each region to realize technology leapfrogging step by step, and make plans for pursuing benchmarks in each technology level. At last, this research will provide decision-making reference for the promotion of regional emission reduction capability.
