基于模糊联盟合作博弈的流域水资源优化配置研究

水资源短缺是我国面临的十分重要的资源问题,随着人口的不断增长,对水资源的需求也逐渐增加。水资源短缺已成为经济发展和社会和谐的一个主要瓶颈,如何将一个流域有限的水资源合理地分配给流域内不同的行政区域、区域内不同的产业是水资源规划与管理领域学术研究的核心内容。流域是一个自然形成的空间范围,往往涉及多个不同的行政区域,流域水资源分配牵涉到流域内不同利益主体,公平有效地进行流域水资源配置以达到水资源的可持续利用已经成为流域经济发展和社会稳定的重要因素。本文采用流域水资源分配的二次配置模型,在流域水资源初次分配当中考虑公平,建立基于用水主体需求的水资源分配优化模型,使得各主体需水量和分配水量的离差平方和最小,并得到初始水资源分配结果;在流域水资源二次分配当中考虑效率,建立流域水资源二次分配的模糊联盟合作博弈模型以最大化流域整体收益,并将由合作带来的流域整体收益的增加部分采用模糊夏普利值的方法分配给参与模糊联盟的各个用水主体,同时流域水资源得到有效再分配。最后,将上述流域水资源二次分配模型运用到一个算例当中,验证了模型本身的有效性和适应性。模糊联盟合作博弈模型对于促进流域水资源规划与管理具有借鉴意义。     

基于区间直觉模糊集的水资源配置群决策研究

水资源问题是我国面临的重要资源与环境问题。流域水资源配置的有效性缺失也使水资源问题进一步恶化,而水资源配置过程中大量不确定信息也使高效决策问题更加困难。基于区间直觉模糊群决策的水资源配置方案优化方法,分析了水资源系统作为复杂系统的特殊性和区间直觉模糊理论在群决策中应用的优势,利用区间模糊数来表达专家判断信息,提高了流域水资源配置方案的合理性。通过多个水资源领域专家的群体决策,从流域水资源可持续利用评价视角出发,针对流域的社会、经济、资源、环境等多个因素进行判断,利用IIWAA算子进行群体意见集成,最后根据流域指标与理想点逼近点的距离对流域水资源配置方案排序。通过赣抚平原灌区内的用水区域在不同方案情景下的水资源可持续利用实例分析表明,该方法能够比较准确地评估出流域水资源配置方案的可持续性,为流域的水资源配置方案制定提供有效合理的决策支持

合作视角下的跨境水资源两级分配模式

跨境水资源是淡水资源的重要组成部分,随着世界人口和经济的快速发展,各国对水资源需求增加,气候变化使水资源变化情势具有不确定性,更是加剧了各国对水资源安全保障的诉求。公平合理的跨境水资源分配对于缓解各流域国用水冲突、实现跨境水资源可持续利用具有重要意义。为提高跨境水资源分配的公平合理性和水资源利用效率,基于合作视角,该研究提出一个“初始分配以明晰所有权+优化再分配以实现高效利用”的跨境水资源两级分配模式。首先基于协商谈判视角,运用讨价还价博弈模型的方法理念,引入流域国间协商谈判机制,以实现跨境水资源在流域国间的公平合理初始分配。然后基于利益共享理念,构建具有模糊支付的跨境水资源合作博弈模型和要素双重模糊的跨境水资源合作博弈模型,探讨不同模糊情景下的跨境水资源优化再分配问题。并以澜沧江-湄公河流域为例进行实证分析,研究表明：(1)基于协商谈判寻求跨境水权分配最优解,可以有效提高分配方案的可接受性。(2)初始分配是流域国开发利用跨境水资源的基础,有利于明晰初始水权,但也存在难以长时间适应流域环境变化和各流域国用水需求变化的缺陷。(3)合作开发情景下的系统收益比非合作情景下的系统收益更高,且当...     

“一带一路”战略背景下金属产业国际产能合作研究

随着全球经济发展放缓,金属资源国内需求结构变化,资源约束压力、产能过剩等问题更加突出。如何通过国际产能合作化解金属产业难题是亟待解决的一个现实问题。本文从中国金属产业的现状出发,借鉴美、日产能转移的成功经验,在"一带一路"战略的大背景下探索适合中国金属产业开展产能合作的新模式并提出相应的政策建议。研究认为,中国已成为世界金属生产和消费大国且工业化进入中后期,具有进行国际产能合作的现实需求,"一带一路"战略为中国金属产能国际转移带来了历史契机。这种契机主要表现在沿线国家的基础设施建设热潮带来全球金属资源消费新的增长点,中国主导的"一带一路"战略构建了一种新型地缘政治格局,既能增强中国在沿线国家中的贸易话语权,也为中国开展国际产能合作提供了条件。研究指出,在"一带一路"战略下,中国金属产业的产能转移应以"互利共赢"为基础创新产能合作模式:即以产能合作推动产能转移,达到产业互补经济互惠的目的;以产能输出取代产品输出,有效回避西方国家针对中国的"双反"政策;以基础设施援建消化部分产能,在帮助沿线国家发展基础设施建设的同时消化自身部分富余产能。在合作策略上,应注重六个方面:一是充分利用"一带一路"的战略合作关系;二是实施低端转移高端做强的策略方针;三是全方位开放和深化产能合作;四是开展境外产业园区建设和有色金属精深加工工程;五是大力鼓励民营资本参与;六是创新金属矿业投资模式。     

基于AHP LP法的南水北调中线水资源优化配置

水资源是不可替代的重要自然资源和战略性经济资源，水资源优化配置是解决水资源问题的重要手段。为促进区域水资源供需状况相对平衡，按可持续发展的要求，根据区域水资源优化配置的含义和南水北调河北省受水区的具体情况，以有限水资源综合效益最大为目标，考虑水源可供水量、用户需水量和水环境与经济系统协调发展等约束，采用层次分析法与线性规划法相结合的方法，建立了水资源优化配置模型，并对模型的目标函数、约束条件和主要参数确定进行了初步探讨。最后用该模型进行了南水北调河北省受水区2005年和2010年95%保证率下的水资源优化配置研究，并对求解结果进行了分析、评价及展望。结果表明，南水北调工程实施后，能够解决河北省受水区严重缺水的状况。     

中国二元经济中水资源流转模式研究

农业用水效率低下及水资源在工农业两部门间的结构性短缺将成为我国经济转型中面临的主要资源问题之一。如何优化配置水资源,实现工农业两部门的"双赢"是经济发展面临的一个重要课题。文章基于刘易斯-费-拉尼斯模型对二元经济结构体制下水资源流转过程进行系统性的经济学阐述,进而得出水资源在工农业两部门中的流转是从无限供给状态到体现稀缺性的过程。并结合1949-2009年中国水资源的利用情况,对中国水资源在两部门经济中的流转进行了阶段识别和趋势研究,即"余水"流转、"低效水"流转和"竞争性用水"流转,从而为水资源流转的实际操作提供了学理性解释,并据此提出通过建设引水工程基础设施、完善用水额度和税费标准法律规范,健全水资源流转的农业补偿机制和加强农业生产部门节水意识宣传,以完善我国水资源流转制度的相应对策建议。     

南水北调东线水资源配置中的期权契约研究

针对南水北调东线实际和传统水资源配置方法的局限性。借鉴金融工程的理念。引入水期权契约作为市场机制下水资源配置的一种方式．用以提高干旱年水供给保证率、规避水价波动风脸,从而提高东线水资源使用价值。分析期权契约理论用于南水北调水资源配置的可行性。并根据东线受水区流域水资源供求缺口的影响因素分析．得出水价的均值回复特性。在上述分析基础上引入多次执行期权契约。考虑应用动态规划方法对期权价值进行求解。并通过算例分析验证了该方法的可行性．最后根据南水北调东线实际构建了水期权契约在东线的应用流程。     

低碳模式下政府参与国际环境合作机制研究

哥本哈根气候大会再次引起了世界对低碳模式的关注,低碳经济的效率与国际环境合作密切相关。政府是国际环境合作的主体。本文通过分析各国政府和国际组织及非政府组织提供的报告与统计资料,指出低碳模式下政府参与国际环境合作存在多种形式,如在国内成立专门处理国际环境合作问题的机构、发起全球性环境会议,谈判具体实施细则、与国际组织和环境非政府组织开展合作、签署国际环境条约等。在对各种形式进行实证分析后发现,国际环境合作目前存在参与、执行、核实和签约模式等方面存在缺陷,因此影响了低碳模式的效率。     

Multicriteria decision-making for efficient water and land resources allocation in irrigated agriculture

The irrational use of water in agriculture is often responsible for several problems concerning the depletion and/or the pollution of water resources. In these cases specific policy measures should be taken to protect water resources from harmful agricultural activities, mitigating at the same time their potential impact on farmers’ welfare. To this end, a multicriteria decision-making model is formulated that aims at allocating efficiently water and land resources in a rural area of Greece, by optimizing a set of important socio-economic and environmental objectives. According to the model’s output, past and current decisions on irrigated agriculture turned out to be oriented towards meeting exclusively the socio-economic objectives. Yet, there are several other possible allocations schemes that could be applied in order to improve the performance of environmental indicators and to contribute to a more sustainable use of natural resources. Moreover, the decision-making model can be further employed to assess a number of additional policy measures in irrigated agriculture. In this framework, the outcome of imposing various water pricing policies was evaluated. The efficiency of these policies was found tightly connected to the elasticity of water demand. Namely, higher elasticity seems to enhance the flexibility in resource allocation and the movement towards environmental objectives.

Research on interest allocation in resource industry chain: taking resources exploitation in China as an example

In this paper, interest allocation in the resource industry chain is studied taking resources exploitation in China as an example. First, qualitative analysis is used to conclude stakeholders and their relationship in mineral resource exploitation. In the following section, using the tool of price constitution and comparison method, the research on interest allocation along the industry chain shows that midstream and downstream companies have advantages. The next section studies interest allocation among resource owners, exploitation companies and local governments. Through contrastive analysis of the financial report of petroleum companies, this paper quantitatively measures the scale of revenue shifting from resource owners, the central and local governments to exploitation companies. This contorted interest allocation is an important factor resulting in exploitation confusion and the large revenue gap.

中国工业水污染排放的空间格局及结构演变研究

我国工业企业污染物排放的空间格局正在发生变化。现有的统计数据不能提供区分区域和行业层面的工业企业污染物排放数据,无法刻画地市尺度上各个工业部门污染排放的空间格局及其演变。工业企业污染物排放的空间认知是制定环境污染控制和区域产业发展规划的科学基础。本文聚焦于工业水污染,构建了新的工业企业水污染排放的空间估算方法,估算分行业分区域的工业水污染排放量,来分析地市尺度上中国工业水污染排放的空间格局及其演变。本文构建的空间估算方法首先将全国分行业污染排放量依据产值分解到省级和地市层面,再依据企业规模校正系数、生产工艺校正系数和环境管制能力校正系数对未考虑区域差异的排放强度进行校正,最后采用适时修正法对污染物排放量的估算结果进行部门和区域的平衡调整。以基于空间估算方法估算的工业COD为例,剔除个别异常值后,2010年省级尺度重点行业工业COD排放量估算结果的平均误差为12.7%,数据质量优良,显示本估算方法较强的适用性。根据本文的结果,发现2005年至2010年间我国工业COD的减排主要由造纸及纸制品业的技术效应贡献,其中又以西部地区造纸及纸制品业贡献突出,其次是东部地区,中部地区略有贡献,东北部地区贡献为负值。其他对工业COD减排作出较大贡献的行业包括食品加工业和化学原料及化学品制造业,但不同产业的区域差异显著。基于可持续性发展的视角,技术效应与规模效应同样显著的产业应当作为区域的主导产业予以重点发展。     

社会选择理论在流域跨界水资源配置冲突决策问题中的应用

本文将社会选择理论引入到流域跨界水资源配置冲突的解决研究中,从群决策的角度寻找到流域内各区域一致同意的、满足水量分配公平的流域水资源配置方案。流域水资源配置冲突问题从表面上看是资源问题,实质上却是一个典型的决策问题。作为一种具有混合特性和稀缺性的自然资源,流域稀缺水资源的分配实质上是多主体参与的涉水利益分配,而分配的核心问题是如何通过合理的群决策机制协调水资源配置冲突中不同行政区域之间的利益关系进而实现公平。本文提出基于社会选择理论的流域跨界水资源配置冲突解决框架,首先从公平性角度将流域水资源配置冲突看成一个短缺资源的配置问题,利用P、AP、CEA和CEL四种破产准则获取可行的水量分配方案集合;其次运用社会选择理论中的PV、BC、HQ、PCM和FB五种偏好聚合方法进行流域内各行政区域个体偏好聚合的群决策分析;通过破产准则与偏好聚合的结合能够实现流域水资源配置冲突群决策结果的公平,所得流域水量分配方案易于被冲突主体所接受。最后,以华北缺水地区的漳河流域跨界水资源配置冲突问题为例进行研究,并比较不同破产准则及偏好聚合方法在解决流域跨界水资源配置冲突中的应用。研究结果表明,社会选择理论与破产准则的结合在解决流域跨界水资源配置冲突问题中具有较高的实用价值。     

Spatial effect of environmental regulation measures on industrial structure upgrading from the empirical analysis of Beijing-Tianjin-Hebei region and its surrounding areas

ABSTRACT

This paper investigates the spatial effect of environmental regulation measures on the upgrading of industrial structure in the integrated development strategy of Beijing-Tianjin-Hebei region and its surrounding areas. In order to reflect the effect of the environmental regulation and different regulation measures more truly, this paper constructs indices of the environmental regulation measures through the results of policy texts quantification. On the basis of the previous research, this paper divides environmental regulation into the following types: personnel and administrative measures of command and control; market-oriented fiscal, taxation, financial and other economic measures; guidance measures. Spatial panel regression results show that administrative measures of command control and market-oriented fiscal measures have a significant role in promoting regional industrial structure upgrading, but not conducive to the advancement of the industrial structure of adjacent areas. Their roles in promoting and inhibition are counteracted, which causes the total effect of industrial structure upgrading of Beijing-Tianjin-Hebei and the surrounding areas are not significant. Personnel measures, financial measures, other economic measures and guidance measures do not have the short-term effect and spatial effect on the upgrading of industrial structure.     

环境约束下中国省际水资源两阶段效率及影响因素研究

本文把水资源利用系统分为水资源利用阶段和污染物处理阶段,在环境规制下采用考虑非期望产出的两阶段SBM模型,对2001—2014年中国31个省级行政区的水资源利用整体效率和各阶段效率进行测度,并利用空间自相关分析方法对中国各地区水资源利用整体效率的时空特征进行分析,然后运用考虑空间效应因素的空间滞后计量模型和空间误差计量模型从人均水资源量、工业用水量、生活用水量、人均GDP、对外开放程度、产业结构、技术进步等方面对各地区水资源利用整体效率的影响因素进行分析。结果表明:(1)整体上看水资源利用第一阶段效率明显高于第二阶段效率,而整体效率接近于第二阶段效率,第二阶段效率决定了水资源利用整体有效性。(2)通过各阶段投入产出冗余来看,水资源污染物产出过多和处理不足是导致第二阶段效率不高的原因。(3)水资源利用整体效率的空间自相关强度显著大于0,在空间上呈现集聚分布特征,东部沿海地区为H-H集聚类型,中部和西部为L-L集聚类型。(4)各地区水资源利用整体效率存在空间溢出效应,一个地区的整体效率不仅受本地区因素影响,还受临近地区整体效率的影响。(5)在考虑和不考虑空间效应的计量估计结果中,工业用水量对整体效率产生显著的负向影响,而人均GDP、对外开放程度对整体效率产生显著的正向影响。根据实证结果,得出以下结论:一是加强水资源污染物排放管理,增强污水处理能力;二是实现高效工业用水,减少工业用水量;三是发挥各地区水资源禀赋优势,加强区域合作,优化水资源区域配置,促进经济-环境协调可持续发展。
