The purpose of this study was to develop and evaluate a Chinese-Mandarin version of the revised new ecological paradigm (NEP-R) scale. In a sample of 515 Mandarin-speaking Chinese nationals, we first assessed the factor structure and internal consistency of the NEP-R and assessed its validity by examining associations with global warming risk perceptions and mitigation behavior. Respondents completed the NEP-R scale, together with measures of risk perception and mitigation behavior. Exploratory and confirmatory factor analyses indicated that a two-factor solution, reflecting ecocentric and anthropocentric worldviews, best fit the data. Multi-group path analysis revealed that respondents with stronger ecocentric and weaker anthropocentric worldviews perceived more risks associated with global warming. In turn, respondents who perceived more risks reported engaging in more global warming mitigation behaviors. But importantly, the path between risk perceptions and behavior was significantly stronger for highly educated respondents than for less educated respondents, suggesting that education may represent an important strategy for bridging the gap between perceived risks about global warming and action. 相似文献

Data Envelopment Analysis (DEA) window analysis with ideal window width is applied to evaluate the green technology innovation efficiency of 28 manufacturing industries in China during 2006–2014. The obtained results are compared with those calculated using the traditional DEA model, and convergence analysis of the efficiency is conducted. Five years is the obtained ideal window width and DEA window analysis with ideal window produces results closer to reality for China's manufacturing industry. The overall efficiency of the green technology innovation in the manufacturing sector is low following a wave-shaped curve – first decreasing, then increasing and decreasing again, with large inter-industrial differences. There are 8 high-, 14 medium- and 6 low-efficiency industries. A convergence trend in the green technology innovation efficiency within the 28 manufacturing industries exists, implying a catch-up effect between them. 相似文献

以江苏省383家众创空间为样本,应用组态思维和QCA方法整合资源与服务两个层面的6个条件,探讨形成众创空间创客集聚差异的多重并发和复杂机理。结果发现:①众创空间高创客集聚存在服务主导型、场地-创客教育主导型、全要素型3个组态,其中,服务主导型、场地-创客教育主导型能深层次、强有力地影响众创空间高创客集聚;②众创空间非高创客集聚存在单纯地产式、单纯线下投资促进、单纯线上投资促进3种组态,且对众创空间非高创客集聚的影响基本相当;③资金资源不充足、场地资源不充足与人员服务不充足在解释非高创客集聚时具有替代作用。 相似文献

Objective: To review, summarize, and analyze both similarities and differences of pharmacoeconomic (PE) guidelines, to enable researchers to access their characteristics and the current state of PE guidelines; furthermore, to learn which methodological issues still remain contested and to promote the methodological development of PE guidelines.Materials and methods: The authors performed a search for PE guidelines using PubMed, the Cochrane library database, and the websites of the International Society for Pharmacoeconomics and Outcomes Research. Information of each guideline was extracted using a pre-designed extraction template, which included 22 aspects; the guidelines were summarized in the forms of charts, and their characteristics have been described.Results: A total of 40 PE guidelines were studied. The most common methodological issues include the types of analysis, sources for effectiveness, use of quality-adjusted life-years (QALYs) to measure outcomes, and use of incremental cost effectiveness ratios to present results. The majority of the guidelines preferred a cost utility analysis with outcomes expressed in terms of QALYs. Most of the guidelines preferred meta-analysis or meta-analysis of the randomized controlled trials, and required a systematic review of all evidence. Issues that varied most in the guidelines were the choice of the comparator, recommended costs to be included, methods related to indirect cost calculations, methods of sensitivity analysis, and discounting rate.Conclusion: A comparison of these guidelines revealed that a number of differences exist among them in several key aspects, and some critical methodological issues still exist, for which no best solution is available. Furthermore, efforts need to be made to develop harmonious methods for the PE, and to improve the transferability of the outcomes of PE evaluations. 相似文献

With increasing environmental competitions between companies, there is a pressing need to explore how the environmental pressures from rivals influence focal firms' actions and the subsequent performance consequences. On the basis of social contagion theory and upper echelons theory, we examine whether firms respond to competitors' green success through green supplier integration, which further improves firm performance, and the moderating effect of organizational ambidexterity. The research explores hypothesized relationships adopting hierarchical regression analysis and bootstrapping method by collecting survey data from 206 Chinese manufacturers. Our findings suggest that competitors' green success positively influences green supplier integration. Green supplier integration mediates the impacts of competitors' green success on financial and environmental performance. In addition, the combined dimension of organizational ambidexterity plays a positive moderating role in the impacts of green supplier integration on financial and environmental performance. This study expands previous literature and managers' practices on green supply chain management. 相似文献

文章利用2010-2015年中国海关数据库与2012年、2014年和2016年中国劳动力动态调查数据,构建了城市出口增速放缓指标及基于全球总体贸易需求下降的"Bartik工具变量",从多维视角有效识别了中国出口增速放缓对区域劳动力市场就业调整的影响效应.研究发现:出口增速放缓显著降低了当地15-64岁劳动力参与工作的概率,出口增长幅度每下降1000美元/人,当地劳动力就业概率则下降3.7%.出口增速放缓使得劳动力在不同部门与不同就业身份之间进行重新配置,制造业和雇员就业概率下降,而服务业和自雇身份就业概率则上升,从而产生就业调整效应.机制检验表明,出口增速放缓对当地可贸易部门的企业绩效造成负面冲击,继而以降低劳动力需求来推动就业调整;而非贸易部门的企业绩效则在一定程度上缓冲了这一冲击.另外,基于当地劳动力失业原因与求职表现的研究进一步为这一机制提供了间接证据.上述研究结论为我国有效化解贸易风险和深入推进就业优先的双重战略目标提供了理论支持和经验证据. 相似文献

ABSTRACTA compact cat swarm optimization scheme (cCSO) is proposed in this paper, which is designed to solve application domains plagued with limited memory and less-computation power, as a member of cat swarm optimization algorithms (CSO), it composes of two sub-modes, i.e., tracing and seeking modes, so it keeps the same search logic of CSO. On the other hand, cCSO inherits the main feature of compact algorithms, a normal probabilistic model is used to represent the population of solutions instead of processing an actual population, which ensures the cCSO to have the modest memory requirement. The updating vector for the probabilistic model provides a clear moving direction for cats in next step. A cat without historical position and velocity is applied in the algorithm. When the cat is in seeking mode, it employs a differential operator to update the cat’s position, which makes it possible for the cat to have multiple searching directions. Experimental results show that cCSO has pretty performance compared with respect to some population-based testing benchmarks. And it also shows superior performance in convergence rate to some compact optimization algorithms. The case study of gray image segmentation proves that it suits for solving the optimization problem by limited hardware. 相似文献
