泛长江三角洲城市旅游经济发展的空间效应

基于泛长江三角洲2002~2012年市域面板数据,并借助面板SDM及空间效应分解方法,对区域城市旅游经济发展及其动力因子的空间效应进行实证分析。结果表明:1区域城市入境和国内旅游发展都存在明显的空间依赖性和空间溢出效应,当邻近城市入境和国内旅游发展水平每提高1%,将促进本城市入境和国内旅游发展水平增加约0.257%和0.312%;2区域城市入境和国内旅游发展各动力因子的空间交互作用也较为明显。旅游资源禀赋、旅游服务设施、旅游交通设施和城市经济发展水平对入境旅游发展具有显著的空间溢出效应,旅游服务设施和城市经济发展水平对国内旅游发展的空间溢出效应也较显著。3保障性因子多为正向溢出,吸引性因子多为负向溢出。前者体现了动力因子的空间模仿效应,后者反映了空间竞争效应。保障性因子和吸引力因子的空间效应强度及作用路径差异推动着区域旅游发展格局不断演进。     

长江中游城市群经济与生态成本空间演化模式分析

综合运用变异系数、泰尔指数及ESDA-GIS多种方法,在充分考虑传统经济影响因子的基础上,尝试引入经济发展生态成本指标,分析长江中游城市群经济综合发展水平与生态成本的空间匹配及演化模式。研究表明:经济综合发展水平高低聚集特征明显,空间极化现象是导致区域经济发展不平衡的主要原因;生态成本空间集聚现象以高高集聚和低低集聚为主,且呈现出高高集聚减少、低低集聚增多的现象,生态成本消耗有所改善;2001~2012年长江中游城市群市域经济综合发展水平与生态成本表现出越来越显著的差异化空间格局,呈现出由低经济综合发展水平-低生态成本过渡到高经济综合发展水平-高生态成本,进而发展到高经济综合发展水平-低生态成本的空间匹配模式的阶段性特征;高经济综合发展水平-高生态成本的经济发展模式仍在大部分城市中存在,经济与生态空间协调发展的潜力仍然很大。     

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。     

上海港对间接腹地经济的作用研究——基于资本路径和物流路径

资本流和物流作为海港对间接腹地经济作用的载体,可以根据其作用路径进行详细分析。通过尝试性地建立面板数据模型,分析海港资本作用枢纽—物流园区、支线港和无水港对间接腹地经济的影响,结合海港对作用枢纽的影响力算法,研究得出上海港通过资本路径对间接腹地生产总值的产出弹性为0.058 6。通过物流路径的系统动力学分析对SD流图进行描述,结合Eviews软件设定各要素的数学方程,选择上海港进行仿真分析,并用历史数据对模型进行检验,误差在可接受的范围之内。进一步对系统进行短期预测,结合预测的结果发现货物运输对间接腹地经济作用的弹性约为0.7。最后分别对上海港主要的吞吐货种进行系统仿真,发现集装箱和石油、天然气及制品的物流运输对间接腹地经济影响最大。     

Listing for change? Exploring the politics of relief lists in Bangladesh after Cyclone Sidr

Ideal notions of efficient aid are challenged continuously by realities on the ground in the wake of major disasters, such as dire needs, limited resources, and opportunism. This paper demonstrates how ‘relief lists’ can be productive entry points for a systematic inquiry into the pervasive politics of disaster assistance. Through an analysis of qualitative data collected during the five years after Cyclone Sidr struck Bangladesh on 15 November 2007, it examines how relief lists featured in both physical and phantom forms and then developed beyond their transparency-making aims, becoming elevated sites of struggle for post-disaster resources. Three list processes, selected to indicate the temporal, material, and spatial dynamics of relief encounters, are assessed in depth. Although recipients of cyclone relief appreciated its value, the paper argues that list politics also stimulated structures of vulnerability, including inequality. Gradually, relief, as governed after Sidr, also served to restore the differential vulnerability of the country's coastal poor.

Green Screen or Smokescreen? Hollywood's Messages about Nature and the Environment

This paper examines ideologies about nature and the environment in popular, animated Hollywood films—including The Lorax, Wall-E, and Ice Age 2—through a symptomatic reading. The primary goal of the analysis is to elucidate key omissions in these texts through an assessment of the problematic—defined in this research as an a-priori answer to perceived audience concerns regarding the role of consumerism and corporate culture in environmental problems. Silences in the films revolve around: how environmental problems are defined; what the consequences are; who the responsible parties are; and what potential solutions exist to mitigate them. The significance of the research is underscored by the formation of an increasingly intimate relationship between children, consumer culture, and commercial media in the USA, as well as the increasingly dire information emerging about global environmental issues. This analysis reveals the dual, often conflicting, messages that commercial film provides for its young audiences about pivotal environmental problems and their potential resolution.     

Reconstituting “America”: The Clean Energy Economy Ventriloquized

With the foregrounding of “clean energy” policies by climate change concerns, the rhetorical constitution of “America” as a collective subject, mobilized to adopt the clean energy economy (CEE), becomes crucial. Here, I analyze the constitutive rhetoric of Pew Charitable Trusts’ landmark 2009 report on the CEE, drawing from the ventriloqual perspective to communication. I argue that this approach provides a more pragmatic, conversational understanding of the interpellative process constituting “America,” noting it to be hybridized and composed of various human and nonhuman agents. Tracing the ingoing interaction among agents—some manifest in the text, others spectral—sheds light on the complex relations of power at stake, recognizes the open-ended possibilities (and restrictions) of agency, and the role of material structures shaping environmental communication and policy.
