Problems on the application of geographic information systems to urban environmental management

Geographic information systems (GIS) are a widely used tool in urban planning and management. More and more cities and decision-makers require its attributes of promptness, precision and visualization. But the application of GIS in urban environmental management is still a new field and relevant researches are getting on tardily. As a subsystem of GIS, an urban environmental management geographic information system (UEMGIS) should be a complex multi-discipline and multi-objective tool to perform quantitative multi-dimension analysis and to transfer the results into an expression legible to an ordinary user. It should be a dynamic system of prompt functions based on upgradable databases, and be composed of many subsystems respectively specialized in items about water, air, waste and noise as well as relative standards and regulations. However, existing UEMGISs mostly rely on the basic GIS too much to design the actual requirements of applications and managements in themselves, and the unavailability of sufficient fundamental data has retarded their improvement. In the design of a UEMGIS, the standardization of data classification should be taken into consideration to make the data exchangeable and shareable among its subsystems and within every subsystem, and the applicable error limits for input data should be defined in accordance with the user抯 required precision of data out. Data acquisition can be easy and quick if remote sensing, global positioning system (GPS) and other technologies are combined with GIS. Rapidly progressing information technologies have been giving a bright prospect for the melioration of UEMGIS that will have great potential and wide application in environmental conservation.

Framework based on building information modeling, mixed reality, and a cloud platform to support information flow in facility management

The quality of information flow management has a remarkable effect on the entire life cycle of buildings.Manual retrieval of technical specifications and features of building components and their performance assessment leads to increased cost and time and efficiency reduction,especially during the facility management(FM)stage.The introduction of building information modeling(BIM)in the construction industry can provide a valuable means of improving the organization and exchange of information.BIM tools integrate multiple levels of information within a single digital model of a building.Nevertheless,the support given by BIM to FM is far from being fully effective.Technicians can benefit from real-time communication with the data repository whenever the need for gathering contextual information and/or updating any data in the digital model arises.The framework proposed in this study aims to develop a system that supports on-site operations.Information requirements have been determined from the analyses of procedures that are usually implemented in the building life cycle.These studies set the standard for the development of a digital model of a building,which will be shared among various actors in charge of FM and accessed via a cloud platform.Moreover,mixed reality is proposed to support specific information that is relevant to geometric features and procedures to be followed by operators.This article presents three use-cases supported by the proposed framework.In addition,this research article describes the first proof of concept regarding real-time support for FM.

GIS-and RS-based spatial decision support:structure of a spatial environmental information system(SEIS)

The development of spatial decision support for environmental resource management,e.g.forest and agroecosystem management,biodiversity conservation,or hydrological planning,started in the 1980s and was the focus of many research groups in the 1990s.The combined availability of spatial data and communication,computing,positioning,geographic information system(GIS)-and remote sensing(RS)-technologies has been responsible for the implementation of complex SDSS since the late 1990s.The regional GIS-based modelling of environmental resources,and therefore ecosystems in general,requires setting-up an extensive geo and model database.Spatial data on topography,soil,climate,land use,hydrology,flora,fauna and anthropogenic activities have to be available.Therefore,GIS-and RS-technologies are of central importance for spatial data handling and analysis.In this context,the structure of spatial environmental information systems(SEIS)is introduced.In SEIS,the input data for environmental resource management are organised in at least seven subinformation systems:base geodata information system(BGDIS),climate information system(CIS),soil information system(SIS),land use information system(LUIS),hydrological information system(HIS),spatial/temporal biodiversity information system(STBIS),forest/agricultural management information system(FAMIS).The major tasks of a SEIS are to(i)provide environmental resource information on a regional level,(ii)analyse the impact of anthropogenic activities and(iii)simulate scenarios of different impacts.

环境问责风险与重污染企业审计费用——基于中央生态环境保护督察的准自然实验研究

本文以2008-2017年我国A股上市制造业企业为样本,以中央生态环境保护督察组进驻为准自然实验,以重污染制造业企业为实验组、非重污染制造业企业为对照组,构建多期双重差分模型,检验环境问责制对重污染企业审计费用的影响。研究发现,环境问责制显著降低重污染企业的审计费用;机制检验发现,环境问责制通过提升重污染企业绿色治理水平、会计信息质量和管理层语调可靠度,来降低重污染企业审计费用;异质性检验发现,在政企关联强、风险承担水平低、地区公众环境关注高的企业,环境问责制对重污染企业审计费用的影响更显著。本研究拓展了中央生态环境保护督察的微观后果,为规范环境风险挑战下重污染企业的审计定价、优化环境规制体系提供理论与决策依据。

绿色信贷指引对重污染企业环境信息披露的影响

在可持续发展战略背景下,国家和民众对环保问题的关注程度日益提高。国家从多方面出台环保政策规制企业行为,绿色信贷便是从银行金融业出发,通过限制金融机构对企业的放贷行为,促使企业经营更低碳环保。基于我国A股上市公司数据,使用双重差分法探究2012年颁布的《绿色信贷指引》对重污染企业环境信息披露的影响,使用词典法和文本分析法对企业年报中“管理层讨论与分析”模块环境信息叙述性披露进行了分析。研究结果显示,绿色信贷政策的颁布确实对重污染企业的环境信息披露有积极影响。具体表现在企业年报的“管理层讨论与分析”模块中有关环保的叙述性披露更多,更具体且更具有可读性;这一结论经过内生性检验、安慰剂检验后依然成立。还探究了该影响的中介效应,发现绿色信贷政策既能直接影响重污染企业环境信息披露,也能通过提高企业融资约束以及环境代理成本使企业加强环境信息披露。此外,企业的所有权性质会对该过程起到调节作用,国有重污染企业会披露更多、更具体的环境信息;股权集中度高的公司倾向披露更少的环境信息,但披露的可读性更高。最后基于以上结论,提出相应的对策建议。

背道而驰还是殊途同归:“环境披露漂绿”与公司价值

以印象管理理论为基础,捕捉企业对外披露的环境信息与实际环保行动之间的分歧,定义其为“环境披露漂绿”,并探讨其与公司价值之间的联系。研究发现,“环境披露漂绿”会对公司价值产生直接的不利影响;更深入的分析结果表明,“环境披露漂绿”会进一步加剧环境信息的价值效应折损;市场信任是“环境披露漂绿”降低公司价值的中介机制。“环境披露漂绿”的治理效应研究发现,提升内部控制质量以增强决策透明性和合规性,防止信息失真;优化市场环境以增强市场监督,提高环境披露透明度和质量;机构投资者凭借其投资分析和风险管理能力,可以有效约束公司行为;媒体作为信息传播渠道,能够揭露企业环境违规行为,推动公司遵守环境规定。
