昌吉市高新技术产业开发区循环经济模式探索及研究

传统开发区内,资源的流动是一些相互不发生关系的线性物质流的叠加,出入系统的物质流远远大于内部交互的物质流,因而造成经济活动的＂高开采、低利用、高排放＂特征,即＂大量生产、大量消费和大量废弃＂[1]。而发展循环经济,是我国贯彻落实科学发展观、建设资源节约型和环境友好型社会的重大战略选择[。2]目前新型开发区产业发展,则要求按照循环经济的理念,积极探索发展循环经济之路。本文以昌吉市高新技术产业开发区为例,研究其循环经济模式,为其他开发区设计和发展提供有益的经验和建议。

运用法律手段加强环境治理工作的有效性

单靠道德自律及经济、行政性处罚等手段 不可能从根本上解决环境问题,唯有加强法律作为硬性强制性手段,才能加大环保工作的有效性。     

A preliminary process design and economic assessment of a catalyst rejuvenation process for waste disposal of refinery spent catalysts

Spent hydroprocessing catalysts from refineries have been classified as hazardous solid waste by the United States Environmental Protection Agency (USEPA), refiners must find a viable but economical solution to solve this serious environmental issue. Catalyst rejuvenation is an attractive option for minimizing the environmental problems associated with spent catalysts. In this study, a preliminary design for such a process and the corresponding economic analysis are performed to assess the proposed catalyst rejuvenation process for metal-fouled spent catalysts generated in residue hydroprocessing units. The scenarios used in the economic assessment are based on three options of process synthesis and two operator modes. It is found that the option of rejuvenating medium and lightly fouled spent catalyst produced by the refinery will be the best solution for refiners, both environmentally and economically.     

CO2 emission driving forces and corresponding mitigation strategies under low-carbon economy mode: evidence from China’s Beijing–Tianjin–Hebei region

On account of the background of China’s “new normal” characterized by slower economic growth, this paper analyses the low-carbon economy status quo in the Beijing–Tianjin–Hebei region and empirically investigates the relationship between carbon dioxide (CO₂) emissions and its various factors for China’s Beijing–Tianjin–Hebei region using panel data econometric technique. We find evidence of existence of Environmental Kuznets Curve. Results also show that economic scale, industrial structure, and urbanization rate are crucial factors to promote CO₂ emissions. However, technological progress, especially the domestic independent research and development, plays a key role in CO₂ emissions abatement. Next, we further analyze the correlation between each subregion and various factors according to Grey Relation Analysis. Thereby, our findings provide important implications for policymakers in air pollution control and CO₂ emissions reduction for this region.     

Formalising informal solid waste recycling at the Pomona dumpsite in Harare,Zimbabwe

The role of informal recycling in poverty alleviation and solid waste management in cities in developing countries has been receiving increased attention. This study explores the integration of the informal recycling sector with the Harare City Council's solid waste management system, focusing on the Pomona dumpsite. The extent of this integration was compared with interventions proposed in InteRa, a new way of evaluating the integration of informal recyclers with the waste management systems of cities in developing countries. Our results suggest that the Harare City Council, which had the vision of transforming itself into a world‐class city, failed to fully integrate the informal recycling sector. We suggest to policymakers that complete integration of the informal sector will not necessarily prevent cities from achieving such visions. Rather, addressing the neglected interventions may help in achieving their visions.     

开放经济、环保财政支出与污染治理——来自中国省级与行业面板数据的经验证据

首先按照各省环保财政支出占GDP比重与按主成分分析法计算的地方环境污染物排放综合指数的排名情况把中国30个省份分成两个区域,区域1环保财政支出污染治理效应较强,区域2环保财政支出污染治理效应较弱。区域1包括北京、海南等14个省市,区域2包括天津、上海等16个省市。其次基于2007—2014年中国省级和行业面板数据,分析开放经济、环保财政支出对污染治理的影响。最后借鉴门限回归模型检验开放经济是否存在环保财政支出与污染治理的门槛效应。结果显示:(1)环境污染物排放存在区域差异和行业差异,区域1呈现出开放程度和污染物排放双低的特征,而区域2则表现为双高特征。制造业、电力、煤气及水的生产和供应业污染物排放较高,采掘业污染物排放年均增长速度最快。(2)样本期内省级和行业面板数据均表明开放经济与环境污染物排放显著负相关,对外开放不是助推环境污染的原因。(3)中国环保财政支出与环境污染物排放显著负相关,环保财政支出具有显著的污染治理效应。(4)开放经济对环保财政支出的污染治理效应具有门槛效应,当进口和出口贸易总额高于门槛值-1.221、-1.016时环保财政支出的污染治理效应很难发挥。(5)以进、出口贸易总额为门槛变量时,有107个观测值低于门槛值,占总观测值的44.58%,其中有59个位于区域1,占55.14%。鉴于此应继续加大环境保护财政支出,进一步提升环保财政专项支出在GDP中所占比重,保持适度的对外开放,优化能源消费结构和实现产业结构升级,全面改善环境质量,提升开放经济下环保财政支出的污染治理效应。
