钢筋混凝土旧工业厂房主体结构的改造加固风险研究

为探索钢筋混凝土旧工业厂房的改造与加固风险,进行了实地调研和基础理论研究,借助SPSS 22.0统计软件对32个二级指标进行筛选,确立6个方面29个指标的改造加固风险评价指标体系,运用结构方程模型（SEM）实证分析关键影响因素及其作用路径。研究结果表明:设计方案、结构特征和施工技术对改造加固风险具有影响;结构特征与设计方案之间的强关联形成了隐性且重要的风险路径。基于关键影响因素及因素间关联关系,对宝鸡市某U型厂房主体结构加固实例提出建议,为此类项目的改造施工提供理论依据。

Exploring the role of local community perceptions in sustainability measurements

Measuring sustainability is an integral part of decision-making processes in order to promote sustainable development. The present paper focuses on sustainability indicators as these are measured on local level and explores two main issues: firstly, the subjective measurement of indicators focusing especially on social dimensions of sustainability, secondly, the incorporation of local perceptions in sustainability assessments. These two issues are explored in the Asopos River basin in Greece, an area where significant environmental degradation has been observed in the past decades and is also under financial pressure due to the ongoing national recession. A large-scale research study was conducted measuring environmental, economic and social indicators while, at a second stage, a model was developed, estimating new indicators that incorporate local communities’ perceptions on what they considered as important for their area. The results of the study reveal that the most important indicators for the sustainable development of the area, according to locals’ perceptions, are environmental quality as well as quality of life. By contrast, trust in local and central institutions and also local enterprises were not considered as important by locals. These results illustrate the importance of combining global and national scale assessment with locally focused social measurements of sustainability in order to better understand what is important for local communities prior to embarking on public policy planning.     

The impact of coal and non-coal consumption on China's energy performance improvement

China is the world's largest energy consumer, and coal accounts for a higher proportion of the country's total energy consumption, yet during its 12th five-year plan (2011–2015), the coal share among total energy consumption significantly decreased. Previous studies exploring energy performance typically used energy consumption as an input, but this lacks the analytical capacity for the structure of energy consumption. Thus, this study splits energy input into two different inputs, coal consumption and non-coal energy consumption, and based on their differences with other variables, uses the hybrid dynamic data envelopment analysis model to assess the energy performance of China's provincial industrial sector during the period 2011 to 2015. We then compare coal consumption's and non-coal consumption's rooms for improvement and conclude that provinces in eastern and central China should reduce the amount of coal consumption, thereby improving energy performance. Conversely, provinces in the western region should target a balance between energy utilization efficiency and coal consumption.     

我国特种劳动防护用品产业分布特点分析

为了解我国特种劳动防护用品产业分布特点和产业市场集中程度,基于生产企业统计数据,估算我国特种劳动防护用品产业市场集中度;对比2017年和2010年数据,统计分析我国特种劳动防护用品产业的区域、产品种类、企业注册资金规模和企业从业人员数量的分布和变化,分析总结了产业发展呈现的特点,提出了加快我国特种劳动防护用品产业发展的相应建议。结果表明:当前我国特种劳动防护用品产业市场结构尚属于低集中竞争型;各区域生产企业数量按照东部、中部、西部和东北的顺序依次递减,东部生产企业占据全国企业总数的65%以上;一半以上企业的注册资金均大于1 000万元;以从业人员数量看,80%以上企业属于小型企业规模;与2010年相比,2017年我国特种劳动防护用品生产企业从业人员数量增加了6.67%,企业从业人员规模分布变化不明显,企业注册资金规模已由约7成企业在500万元以下转变为近7成超过500万元,产品种类增加了40%。研究结果可为我国劳动防护用品产业和安全产业的发展提供科学参考。
