泛珠三角经济差异的时空演进和影响因素探析

泛珠三角是横跨东中西部,包含沿海发达地区和内地欠发达地区的经济合作区。探析泛珠区域内经济发展差异的时空演变格局,并利用空间计量方法对影响泛珠地区经济发展的因素进行实证研究。结果表明:泛珠三角地区以沿海城市群和内陆各省会城市为中心的中心-边缘结构分布显著;区域内空间自相关趋势在加强,空间集聚现象显著;从时间和空间维度上都表明内部经济差异在缩小,区域合作取得一定效果;人均GDP总体空间格局稳定,局域内发生演变,人均GDP增长速度的冷热点区域变化较为明显。空间计量表明,工业化对区域经济发展影响显著,城镇化是促进经济增长的重要途径,城镇劳动人口没能充分发挥作用,表现出城镇就业人口的规模不经济。     

我国“一带一路”沿线地区风险投资时空分布及影响因素研究

深入分析我国“一带一路”沿线地区风险投资时空格局及影响因素,有助于促进创新创业与企业发展、提高区域科技创新水平。运用空间分析方法和空间计量模型,对2003-2018年我国“一带一路”沿线139个城市风险投资的时空分布特征及影响因素进行分析,结果表明：①沿线地区的风险投资发展具有不均衡性,呈现为沿海高、西部低的分异格局;②风险投资的全局自相关系数均为正,呈现出明显的空间集聚特征;③风险投资机构数、国家高新区数量、风险投资退出、政府引导基金发展、财政科技支出对区域风险投资具有显著促进作用,环境污染对风险投资有一定抑制作用。随着ESG投资理念逐渐获得认可,沿线地区可以通过提升绿色发展水平促进风险投资发展。     

物料流量会计的深化——利用MFCA与LCA的整合评估外部损害成本

物料流量成本会计(MFCA)是一种环境管理会计运用工具,也是企业高级管理人员和现场生产经理制定决定的一种工具.MFCA通过减少废弃物来实现提高生产能力的目标.MFCA衡量了材料的物量和存量信息,即在生产过程中的原材料、备品备件以物流和货币的单位表示出来,将MFCA与生命周期评价(LCA)整合,以此来评估外部损害成本.     

导致我国上市公司出现财务舞弊的因素分析

我国资本市场目前得到快速的发展,取得的成就备受瞩目,但是随之而来的上市公司中出现的财务舞弊现象是越来越严重,这不但对上市公司的健康发展造成伤害,同时对资本市场的资源配置运行带来了破坏,并且使上市公司的财务报告和由此而形成的审计报告都丧失了应有的风险预警的作用。在总结原有研究结论的基础之上分析现在我国上市公司的财务舞弊的动机,并提出相应治理建议,以期对我国的证劵市场中的财务舞弊现象起到遏制的作用。     

Environmental regulation and trade pattern：a case of China

As a growing number of countries, including both developed and developing countries, have in recent yearstaken environmental regulation at different levels, a question of great concern has been raised： can the regulation alterthe existing trade volume and trade pattern, and ultimately drive pollution-intensive industries to countries with low-levelregulations or even those without regulations at all？ Starting from the three different propositions concerning therelationship between environmental regulation and trade pattern, this paper applies cointegration analysis and errorcorrection model to empirically testing the relationship between environmental regulation and trade in China during theperiod of 1985-2005. Our empirical results indicate that in the short run the collection of pollution discharge fees bearsa positive impact on the export share of clean products of total exports. Thus, higher pollution discharge fees raise theratio of clean products exports to total exports. This further indicates that more stringent environmental regulationpromotes the exports of clean products. In the long run pollution discharge fees are positively correlated with the exportshare of clean products but negatively associated with their import share. Such correlations imply that environmentalregulation tends to facilitate the international specialization in line with comparative advantages.     

网络口碑营销研究进展述评

本文对CNKI和ISI数据库中167篇网络口碑营销的文献进行了研究主题和研究方法的分析。结果发现,国内在网络口碑营销的研究内容和理论深度上与国外相比存在明显的滞后。国外研究主题侧重于网络口碑与消费者行为关系、网络口碑效应以及网络口碑可信度等方面。国外以调查实证和实验研究方法为主,国内则以描述性为主。未来可以通过调查或实验方法就中性网络口碑的作用以及网络口碑作用机理等开展研究。     

THE DISTRIBUTION OF WEALTH IN URBAN CHINA AND IN CHINA AS A WHOLE IN 1995

The composition, inequality and determinants of wealth among households in urban China in 1995 are studied. In addition, we compare the wealth distribution in urban China with the wealth distribution in rural China and present the first estimates of inequality in the distribution of household wealth in China as a whole. The results show that housing wealth makes up a large part of net worth in urban China. Most urban Chinese households keep a bank account; debts are unusual. A household's net worth is strongly related to its income and location. Net worth is more unequally distributed among urban households than among rural households. However, compared to the situation in most industrialized countries, net worth in urban China and in China as a whole appear to be rather equally distributed.

智慧BIM乔木模型：从设计图纸到施工 现场

现有的BIM应用软件提供的乔木模型多为RPC或高 精度3D模型等3D CAD类型。这些模型着重于表达美感或进 行展示,无法反映根系情况。虽然可能包含一定附加属性,但 表达乔木生长和空间需求的功能有限。因而,冲突检查、工序 调度等BIM的优势功能无从应用。风景园林实践领域已就此问 题开始构建自己的模型库,但能够准确反映现状树木真实尺寸 体量,以及现状树木和规划树木未来空间需求的模型仍未广泛 出现。提出一种基于树冠、树干和根系构型与生长功能的实体/ 网面封装建模方法构建BIM乔木模型。模型形态通过一组参数 调整,并根据树龄和反映环境限制因子的值来反映其变化。所 包含的数据和参数数量随后期设计阶段所需的LoD(详细层级) 及专业实践的具体要求而增加。该模型可以与提供本地区内外 苗木商品信息的植物数据库连接使用。     

The economic burden of common adverse events associated with metastatic colorectal cancer treatment in the United States

Aims: Adverse events (AEs) associated with treatments for metastatic colorectal cancer (mCRC) may compromise the course of treatment, impact quality-of-life, and increase healthcare resource utilization. This study assessed the direct healthcare costs of common AEs among mCRC patients in the US.

Methods: Adult mCRC patients treated with chemotherapy or targeted therapies were identified from administrative claims databases (2009–2014). Up to the first three mCRC treatment episodes per patient were considered and categorized as with or without the AE system/organ category during the episode. Total healthcare costs (2014 USD) were measured by treatment episode and reported on a monthly basis. Treatment episodes with the AE category were matched by treatment type and line of treatment to those without the AE category. Adjusted total cost differences were estimated by comparing costs during treatment episodes with vs without the AE category using multivariate regression models; p-values were estimated with bootstrap.

Results: A total of 4158 patients with ≥1 mCRC treatment episode were included (mean age?=?59 years; 58% male; 60% with liver and 14% with lung metastases; 2,261 [54%] with a second and 1,115 [27%] with a third episode). On average, two treatment episodes were observed per patient with an average length of 166 days per episode. Adjusted monthly total cost difference by AE category included hematologic ($1,480), respiratory ($1,253), endocrine/metabolic ($1,213), central nervous system (CNS; $1,136), and cardiovascular ($1,036; all p?Limitations: Claims do not include information on the cause of AEs, and potentially less severe AEs may not have been reported by the physician when billing the medical service. This study aimed to assess the association between costs and AEs and not the causation of AEs by treatment.

Conclusions: The most costly AEs among mCRC patients were hematologic, followed by respiratory, endocrine/metabolic, CNS, and cardiovascular.
