产学研融合程度对科技型中小企业创新绩效的影响

构建产学研深度融合的技术创新体系,是我国为应对当前复杂多变的国际环境、满足新时代高质量发展要求的重要战略。基于产学研融合内涵,构建微观层面企业产学研融合程度综合评价模型,实证检验产学研融合程度对科技型中小企业创新绩效的影响以及环境不确定性的调节作用。结果表明,我国科技型中小企业产学研融合广度、深度和频度总体均呈波动上升趋势,正逐步迈向深度融合阶段;产学研融合广度和深度对科技型中小企业创新绩效具有正向影响,产学研融合频度对科技型中小企业创新绩效具有负向影响;环境不确定性会增强产学研融合广度对科技型中小企业创新绩效的正向影响,削弱产学研融合深度对科技型中小企业创新绩效的正向影响,增强产学研融合频度对科技型中小企业创新绩效的负向影响。结论可拓展产学研合作相关研究,发展产学研融合理论,为解决我国科技型中小企业产学研融合效率偏低、机制不佳等问题提供实践指导。

环境规制与中国外商直接投资变化——基于DEA多重分解的实证研究

中国经济进入“新常态”,产能过剩和环境污染问题日益突出,国际投资环境不容乐观,“供给侧结构性改革”为中国经济“新常态”下的必要举措。本文探索环境规制下我国FDI变化的影响因素,通过FDI的子向量距离函数定义“环境规制生产技术”和“非环境规制生产技术”,以此构造环境规制的成本效应,测度中国30个省份1999-2015年的环境规制成本,并在此基础上对实际FDI的变化进行分解。本文的主要结论有:2001年后,中国各省份的环境规制成本呈现整体上升趋势,东部地区的环境规制效果最为明显;环境规制下,中国各省份的实际FDI增速先加快后减缓,2015年之前,第二产业对FDI的吸引力最强,2014年开始,第三产业对FDI的吸引显著增强,“供给侧结构性改革”初显成效,促进了我国的产业结构优化升级。反事实检验显示导致各个时期FDI变化的影响因素不尽相同,但随着改革开放的力度不断加大,全要素生产率和产业结构对FDI分布的影响显著增强。     

Management and employee involvement in achieving an environmental action-based competitive advantage: an empirical study

The objective of this work is to conduct an empirical study that shows whether certain management and human resource factors influence the achievement of an environmental action-based competitive advantage in a company. To this end, we have taken a sample of 110 factories. Management's deep involvement and its strategic integration, as well as employee motivation and participation, have a positive impact on the achievement of an environmental action-based competitive advantage in a company.     

Altruistic or egoistic: Which value promotes organic food consumption among young consumers? A study in the context of a developing nation

The present research attempts to understand the importance of altruistic and egoistic value in determining the young consumers’ intention to buy organic food. Environmental concern was considered as the altruistic value, whereas health concern as egoistic value. Using the convenience sampling method, a total of 304 usable responses was collected from young consumers, with the help of self administered questionnaire survey approach. Data analysis was done using two step structural equation modeling (SEM) approach, i.e. measurement model and structural model. Findings indicated that, both altruistic as well as egoistic value influences the intention to buy organic food among young Indian consumers. However, egoistic value was found to have more impact on the consumers’ organic food purchase intention. The present research is one of the initial attempts in the Indian context to understand the importance of values (altruistic and egoistic) organic food consumption among young consumers.     

中国船舶工业绿色全要素生产率及影响因素分析——基于ML生产率视角对“波特假说”的再检验

选用船舶工业宏观数据和资源环境约束等作为基础数据,运用方向性距离函数和ML指数测算了中国船舶工业绿色全要素生产率(Total Factor Productivity),通过面板模型系统考察了环境规制、技术进步对中国船舶工业绿色全要素生产率的作用。发现从长远来看,绿色全要素生产率呈增长趋势且具有明显的收敛特征,技术进步和技术效率共同推动船舶工业绿色全要素生产率的增长,但整体上绿色全要素生产率低于传统全要素生产率。运用动态面板模型分析中国船舶工业绿色全要素生产率的影响因素,结论表明:较高的技术水平能显著提高绿色全要素生产率,而对国际市场的过度依赖阻碍了船舶工业绿色全要素生产率的增长。环境规制对船舶工业绿色全要素的增长已经带来"补偿效应"从而提高了中国船舶工业的国际竞争力,为考察船舶工业绿色竞争力提供了新的视角。     

Recreation and the Environment as Cultural Dimensions in Contemporary American Society

This paper broadly explores changing outdoor recreation demands, environmental opinions and demographics in the United States. With this country's population predicted to more than double by the end of this century, it is imperative that we understand these trends and their implications for better managing our natural environment and providing opportunities for outdoor recreation in that environment. Using national survey data, we have described differences in recreation behavior (participation) and environmental attitudes nationwide across six socio-demographic factors-race, country of birth, rural-urban residence, region of the country, age and income. Results indicate that demographic differences, recreation activity choices and people's environmental positions are linked.     

Voluntary carbon offsetting: Who does it?

Voluntary carbon offsetting was popularised during the last decade, particularly by airlines, as a tool to ‘neutralise’ emissions associated with travel. Although there is a wide range of carbon offsetting schemes for tourism, the uptake of these programs has been reportedly low. Regardless, little research has explored the visitor segments who voluntarily undertake carbon offsetting. Consequently, this research investigates the prevalence of carbon offsetting amongst international tourists to Australia between 2008 and 2010 and, using cluster analysis, segments the carbon offsetters into three distinct markets. Findings reveal a stable carbon offsetting market, despite a Global Financial Crisis occurring during the reference period. Further, travellers from the United Kingdom/Europe were more likely to carbon offset, while those from Asia were less likely to participate in the schemes. Thus, this could indicate that the social marketing, public discourse and substantial media coverage in the United Kingdom/Europe had enhanced climate change mitigation behaviours.     

核心企业治理能力对模块化组织价值创新的影响

模块化组织中核心企业治理能力直接关系到组织价值创新绩效。构建了核心企业治理能力影响模块化组织价值创新的概念模型,并将环境动态性作为调节变量引入该模型。基于268家以模块化方式运行的样本企业数据开展实证研究发现：核心企业治理能力所包含的系统设计能力、合作主导能力、关系协调能力和知识重构能力均对模块化组织价值创新产生了正向影响。其中,系统设计能力对组织价值创新的促进作用最大,其它依次为关系协调能力、知识重构能力和合作主导能力;在环境动态性的调节作用下,核心企业关系协调能力和知识重构能力会增强对组织价值创新的正向影响,而系统设计能力和合作主导能力会削弱对组织价值创新的正向影响。     

Indoor air quality in mass catering plants: Occurrence of airborne eumycetes in a university canteen

The present study aimed to investigate the viable eumycetes population of indoor air sampled in a mass catering plant that produces up to 1200 meals per day. The combination of a culture-dependent and -independent approach applied in the food-processing environment was efficient for the identification of airborne eumycetes. Penicillum, Cladosporium and Alternaria were the dominant genera, while Thysanophora, Aspergillus, Rhizopus, Annulohypoxylon, Arthrinium, Aureobasidium and Trametes were found to be in minority. The size and composition of the eumycetes population found in this study do not raise specific concerns. Nevertheless, a quantitative and qualitative monitoring of these bioaerosol should be included in the progress and criticality reports of the HACCP system in the catering services where eumycetes can pose different risks, such as worsening of the overall quality of meals and/or of the work environment. Indeed, these reports are a useful tool in the preventive HACCP approach, provided that an adequate frequency of sampling is planned in order to quicken the pre-warning process.
