资源环境约束下宁夏经济增长方式转变研究

面对宁夏资源约束趋紧、环境污染严重、生态系统退化的严峻形势,在生态文明理念下研究其经济增长方式转变就很有必要.文章在前人相关研究的基础上,采用一个包含能源要素的二级CES生产函数研究了宁夏资源环境约束下的经济增长问题,在这个扩展的模型中忽略了技术因素,增加了环境对宁夏经济增长的影响分析.结果表明：推动宁夏经济增长的要素中,资本的贡献最大,其次是能源,劳动力的贡献最低.同时,经济增长的环境代价也很高.根据研究结论,提出了转变经济增长方式的具体改进措施.     

我国西部地区能源效率及影响因素研究

本文通过构建DEA模型研究西部地区1990-2016年的能源效率水平,接着运用面板数据实证分析了影响能源效率的因素。结果显示:西部地区能源效率水平差异较大,个别省份在谋求经济发展过程中存在能源浪费现象,节能潜力和改进空间巨大;经济发展水平、产业结构、能源消费结构、科学技术水平、对外开放程度、政府干预、要素禀赋结构对西部地区的能源效率有显著影响。据此,本文提出了相应的能源效率提升建议。     

对于能源利用、环境质量与经济发展的关系研究

经济增长方式转变既是中国经济突破现有发展瓶颈的关键,也是当前理论界的焦点。本文通过数据在能源利用、环境质量与经济发展之间进行分析,发现人均名义收入与环境质量之间的关系可以通过库兹涅茨倒U形曲线来反映。随着人均收入的增加,环境污染物总量将缓慢下降;其中二氧化硫的排放量与人均收入之间的关系是和库兹涅茨曲线理论一致的显示成倒U形的曲线,但人均收入与其他三个环境指标没有类似的关系;虽然近年来能源利用效率稳步增长,但经济增长严重依赖于自然资源,粗放型的经济增长方式依然存在。因此调整产业结构、改善生态环境系统对改善环境污染实现经济持续稳定增长具有非常总要的作用。     

数字普惠金融、融资约束与环境敏感企业投资效率 ——基于1173家上市企业面板数据

利用中国1173家由绿色产业和"两高"行业构成的环境敏感上市企业面板数据,检验数字普惠金融对环境敏感企业投资效率的影响.结果显示:(1)数字普惠金融有助于降低环境敏感企业现金流敏感性,提升这类企业可用于投资的现金利用效率;(2)受数字普惠金融影响,绿色产业企业相比"两高"行业企业投资效率提升更明显,子维度覆盖广度比使用深度对投资效率影响更小;(3)在融资约束中介作用下,数字惠普金融能够缓解融资约束,最终改善投资不足类型企业投资效率,但促进了投资过度企业的无效投资.     

尽快调整资源税政策 促进资源节约

我国改革开放以来GDP高速增长,但同时付出了自然资源过度消耗和环境污染过重的代价,导致当前经济发展瓶颈从过去的资金、技术和基础设施约束,转变为以高消耗、高污染为特点的资源紧缺约束,且有不断加剧的趋势。具体表现为:一是能源运用效率低、消耗大,在此状况下,国内资源禀     

中国商业银行风险约束效率变化分析--基于Super-SBM-Malmquist 模型的测度

随着中国经济由高速增长向高质量增长转变,商业银行面临的经营环境发生了显著的变化,这推动着银行运营模式的变革并对其效率变化产生了重要影响。本文以2009~2019年中国39家商业银行为样本,运用Super-SBM-Malmquist模型,将风险和效率相结合,对中国商业银行风险约束效率进行测度,对不同类型银行的效率差异及其原因进行解释。结果表明:2009~2019年中国商业银行风险约束效率呈总体上升态势,技术进步是导致效率提升以及不同类型银行效率差异的关键因素,这反映在银行业务模式对经济环境变化的适应性上。鉴于此,商业银行应以技术进步推动创新,不断提高核心竞争力,进而提高经营效率。     

供给侧结构性改革下我国能源发展方式与政策建议的研究

当下我国需要面对经济发展中的产能过剩、环境污染、环保资源约束、能源利用率低下等诸多问题,这些问题不利于我国经济增长方式的转变,影响了人们的生产生活,是外部不经济性。供给侧结构性改革提出,正是解决能源结构失衡等一系列问题,达到能源资源的优化配置,从而促进我国经济与能源健康绿色的发展,是一种集约型、绿色可持续发展的路径。本文首先分析了我国能源的发展方式,主要从能源的低碳绿色和能源新动能的两个方面分析;最后本文分别从市场定位、政府定位,发展能源新技术提出相关的政策建议。     

中国区域绿色全要素生产率的影响因素及其空间特征

运用非径向非角度的SBM方向性距离函数与ML指数,将环境污染和能源消耗纳入生产率分析框架,将绿色全要素生产率(GTFP)增长分解为技术进步和技术效率改善,测度中国30个省市区GTFP,利用空间计量模型考量GTFP的影响因素及其空间特征。结果表明：样本期内全国平均GTFP累积增长31%,技术进步贡献较大。各地区的GTFP均呈现增长趋势,而技术效率则有所下降。地理邻接是空间溢出的主要途径,各变量对GTFP、技术进步和技术效率改善的直接效应和空间溢出效应呈现不同的作用机制,R&D投入、外商投资和环境管制等因素对GTFP的增长均有显著影响。     

云南生态文明示范区区域经济可持续发展路径研究

云南省生态文明示范区经济的可持续发展一直受到资源—环境的双重约束,使得长期陷入一种"绿色贫困"的陷阱中。基于此,本文建立了以Lucas内生增长模型为基础,同时将自然资源与环境污染引入生产函数与效用函数,构建资源—环境双重约束下的内生增长模型。意在探索生态文明示范区作为人类经济发展与自然环境组成的复合生态系统,在生态环境约束和自然资源约束条件下云南省生态文明示范区建设的经济可持续发展路线。     

数字普惠金融发展促进了城市创新吗?——基于空间溢出和门槛特征的实证分析

本文以我国2011-2016年248个地级市作为样本,利用北京大学数字普惠金融指数市级数据,基于空间面板模型和门槛面板模型,实证检验数字普惠金融发展与城市创新之间的空间关系和非线性特征。研究结果表明:第一,数字普惠金融发展水平的提升不仅对本地区创新有显著的正向作用,其溢出效应也带动了周边城市创新能力的提升。第二,数字普惠金融的发展对于城市创新的影响具有显著的门槛特征,当超过门槛值时,数字普惠金融发展对于城市创新影响的边际收益增加,在考虑区域差异性后该门槛特征仍然存在。第三,数字普惠金融发展的创新激励效应随着地区经济发展水平的提高呈现出边际收益递增的特征。基于以上研究结论,为了进一步提升城市的创新能力,应尽快转变经济发展模式,优化创新环境,激发数字普惠金融在城市发展过程中的“梅特卡夫法则”效应。     

Short-sale refinancing and price adjustment speed to bad news: Evidence from a quasi-natural experiment in China

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.

The case for management history

This article defines the case for treating management history as a discrete subject area, although one closely related to business, accounting, labour, and industrial history. It seeks to concentrate on the nature, process, and practice of management as an activity within the organization, and to argue that it is important that modern British managers understand the intellectual and cultural roots of their profession, since without these they will tend to be swayed by short-term management 'fads'. Within the broad topic there are several identifiable sub-areas for potential exploration, including the comparative historical development of management between different countries, management institutions, managerial careers and labour markets, management structures, management skills, and management thought and theory.     

Cost accounting standard and cost accounting systems in Japan. Lessons from the past - recovering lost traditions

This paper aims to show two things. The first is how Japanese culture has contributed to the development of Japanese cost accounting history. The second is to reveal the research possibilities of cost accounting history. This paper also reviews the salient features of several important examples of these aspects of cost accounting practice in Japan. It therefore explores, through some practical illustrations, how and why Japanese cost accounting differs from that found in the West.
