竞争市场中生产与碳交易策略

在碳排放约束下,利用动态古诺模型,分析厂商如何优化产量、交易碳排放权的规模、净化节约额以实现利润最大化的问题,得到相应的均衡量和各阶段最优量,并给出竞争市场中的企业减排策略以及政府的行为和碳排放权价格对企业减排策略的影响,阐述在竞争市场中减排和碳排放权交易的运行机制。研究发现: 双寡头竞争市场中存在均衡状态;在减排率较低时,制造上获得最高利润,而企业追求过高的减排率将会导致过分依赖碳减排市场而获得较低的利润;制造商应该适时低价购入过量碳排放权,而在高价时卖出多余的碳排放权,以充分利用碳排放权市场以增加利润降低成本;制造商的利润会随着政府碳排放权分配系数的增加而增加。     

减排约束下中国天然气供需安全评价:2006-2014年

为准确把握中国天然气供需安全状态,以2006-2014年的数据为样本,在模糊隶属度函数量化指标值的基础上,运用层次分析法(AHP)和熵值法确定指标权重,基于线性加权和函数计算均方根进行综合评价。结果表明:(1)中国天然气供需安全指数呈现"N形"波动,2006-2007年天然气供需安全指数上升。2007-2013年天然气供需安全指数年均下降1.7979。2013年以来天然气供需安全指数开始回升,天然气供需安全压力有所缓解。(2)天然气供应安全指数从2006年的17.5914下降到2013年的0.1556,峰谷差17.4359。天然气需求安全指数呈现"W形"波动。天然气市场安全指数相对稳定,2013年以来略有上升,天然气市场风险逐年下降。(3)天然气供需安全很大程度上取决于天然气供应是否安全。因此,建议从确保天然气稳定供应、提高天然气使用效率和降低市场风险方面采取措施,维护天然气供需安全。     

晚清四川鸦片贸易及其相关问题研究

晚清时期,受鸦片暴利的驱使,四川省广种鸦片,川土的销售和消费都很旺盛,烟土税也成为全省重要的财政来源之一.但旺盛的鸦片生产和贸易严重干扰了人们的正常生产和生活秩序,引起了乡村地区生产结构的巨大变动,使经济与社会发展更趋畸形,因而四川也成为了禁烟的重点省份.经过几届政府官吏的努力,四川省的鸦片在清朝覆灭前几乎禁绝,有力地维护了社会正义,但也使当时一些农民的生计受到影响.     

高校实施ISO9000标准的若干问题探讨

ISO9000族标准是国际标准化组织颁布的世界通用的质量管理标准。目前,国内一些高等学校开始按照ISO9000标准建立质量管理体系。电子科技大学中山学院在这种背景下,在全院范围内推行ISO9000质量管理体系。在这一过程中,产生了一些值得探讨的问题,出现了一些实际操作的难点,现提出来与大家共同探讨。     

建设节约型社会的理性思考

工业文明以来,石油危机、海啸等一系列生态危机就人类对资源的保护和利用问题敲响了警钟。为了实现人与自然的和谐、可持续发展,实现全面建设小康社会的目标,2004年初,我国政府正式提出建设节约型社会,使资源得到节约使用,环境得到保护,人民生活更加文明、健康、科学,经济与社会持续发展。建设节约型社会是可持续发展不可分割的部分,是构建和谐社会的重要保证,是中国现代化的根本出路,关系到中华民族的兴衰与长期发展,也关系到全人类的幸福与明天。本文主要研究节约型社会作为节约系统工程的评价及体系构建,以期更好地建设节约型社会。     

“双碳”目标下农业生态效率测度及影响因素分析

农业生态效率是农业经济和生态环保协调发展的重要体现。文章首先引入农业碳汇效应,构建农业生态效率测度指标体系;其次,基于2010—2019年中国31个省市面板数据,运用熵权法改进的超效率SBM测算各地区农业生态效率;然后运用面板Tobit模型探究农业生态效率影响因素。结果发现：2010—2019年中国农业生态效率总体呈现平稳上升态势,空间上呈现东北地区最高、东部次之、西部较低、中部最低的分布格局;财政支农程度、工业化程度、农业自然环境、农业机械密度对农业生态效率产生负向影响;农业环境规制、科技支持力度、农业资源禀赋、农业人力资本和农业生产能力对农业生态效率产生正向影响。最后,提出合理投入农业要素资源;促进农业生产增长;加大农业科技研发和推广力度;提高农业劳动力素质等建议。     

Monitoring S3: Key dimensions and implications

Our work analyses the implications of a smart specialisation strategy (S3) monitoring model based on a system that considers three main axes linked to the logic of the strategies: output/results, smart specialisation process, and a learning component, on which we build our main approach. This strategic learning is based on the logic that S3 presents a new paradigm within the innovation policy scope that requires the inclusion of monitoring schemes that integrate the assessment of the dynamic process under which both public administration and other innovation stakeholders learn and improve their activities (within and without the strategy) thanks to the learning gathered throughout S3 (and its instruments and projects) implementation. The article also discusses this logic within the current and the next programming period for S3, and the role monitoring has or will have, while analysing the opportunities and challenges it presents.     

A systematic literature review of the etiology of borderline personality disorder from an ecological systems PERSPECTIVE

Borderline Personality Disorder (BPD) is one of the most common, complex, costly, and severely impairing personality disorders, affecting an estimated 2% to 9% of the general population and 40% to 44% of the inpatient psychiatric population. A review of the literature was conducted using a systematic methodology. By incorporating an ecological systems perspective, a holistic and comprehensive critique of the literature surrounding the etiology of BPD is presented. The findings reveal that the etiology of BPD is a complex integration of psychological, biological, and social factors. More specifically, however, this review found that: (1) the etiology of BPD is complex and has many factors, (2) the dominant discourse about the etiology of BPD is based primarily in the psychological and biological literature, and (3) the examination of BPD etiology has focused solely on the individual and microsystems levels, neglecting to consider systemic factors such as the impact of discriminatory health and mental healthcare practices. Findings and future directions are explored through the ecological systems theory lens.     

Enabling children’s deliberation in deliberative systems: schools as a mediating space

In recent years, there has been a growing scholarly interest in conceptualising schools beyond their educational functions, as sites and agents of democracy. Yet this interest is often underpinned by a narrow conception of democracy, focusing solely on schools’ public and social aspects. To capture the democratic potential of schools more fully, this article suggests adopting a deliberative systems approach, which conceptualises democracy as differentiated yet linked sites of democratic communications and views schools as one such site. Using this approach as a broader framework and drawing on the fieldwork conducted in two Japanese schools, this article identifies the condition under which schools can become a meaningful part of deliberative systems. It reveals that schools contribute to deliberative systems when they serve as a bridge between children’s everyday practices and deliberative actions in the public space. In light of the findings, this article suggests conceptualising schools as a ‘mediating space’.     

Interactive profit-planning systems and market turbulence: A dynamic capabilities perspective

This article describes, theorizes and empirically investigates the concept of interactive profit-planning systems (PPS) through the lens of the dynamic capabilities logic. With this conceptualization: interactive PPS capabilities comprise budgeting, forecasting and results-reporting routines, in which top and middle managers interact to create knowledge for sensing, seizing, and business model reconfiguring (to manage strategic business change). Survey data from 331 Australian firms is analyzed employing partial least squares structural equation modeling. The data provides support for two hypotheses: (1) greater market turbulence strengthens the positive effect of interactive PPS capabilities on business unit performance; and (2) greater market turbulence strengthens the positive effect of flexibility values (of organizational culture) on interactive PPS capabilities. Our findings show that interactive PPS capabilities function according to the salient tenets of the dynamic capabilities logic, and clarify the beneficial roles of formal cybernetic control systems and the intertwined involvement of top and middle managers in using dynamic capabilities.
