This study utilizes structural equation modeling (SEM) to explore the positive effect of corporate environmental ethics on competitive advantage in the Taiwanese manufacturing industry via the mediator: green innovation performance. This study divides green innovation into green product innovation and green process innovation. The empirical results show that corporate environmental ethics positively affects green product innovation and green process innovation. In addition, this study verifies that green product innovation mediates the positive relationship between corporate environmental ethics and competitive advantage, but green process innovation does not. Therefore, corporate environmental ethics can not only affect competitive advantage directly, but also influence it indirectly via green product innovation in the Taiwanese manufacturing industry. Taiwanese manufacturing companies can increase their corporate environmental ethics and green product innovation to enhance their competitive advantages.  相似文献

Persons in the manufacturing and retail professions will continue to increase utilization of computer technology to assist in merchandising and management operations, and students need to be familiar with the use of technology as a tool. Attention needs to be directed at the underlying objectives for using microcomputers in the learning process. This paper focuses on the intergration of selected cognitive principles of instruction for developing a course in which students use the microcomputer as an analytical and evaluative tool.  相似文献

This paper examines how the perception on green environment can affect consumer behaviour. It tests whether consumer behaviour responds to environmental change. This study captures the interaction between green environment perception and behaviour. A neural network analysis is used to address this challenge to model such a behaviour. A total of 462 interviews were conducted and analysed using neural network process. A Scaled Conjugate Gradient with random data division was used in training and the performance was calculated using mean square error. The result reveals that perception–behaviour gap exists across generations on green environment. It indicates that perception on green producing, green living, green transport and green product is an important factor in determining the behaviour on green consumption. The neural network accurately recognized green behaviour up to nearly 82% with MSE = 0.09 at epoch 31, which is a high level of recognition accuracy. This study underlines the existence of perception–behaviour gap on green environment. However, these are only identified to people with low‐to‐medium level of green behaviours (level of correct only 44.5% and 30%). People with high level of green behaviour in fact show consistency between their perceptions and behaviours (level of correct 96.4%). This result shows that people tend to have higher perceptions on green environment, but their behaviour reflects otherwise.  相似文献

The purpose of this study was to explore whether the performance of the green innovation brought positive effect to the competitive advantage. This study found that the performances of the green product innovation and green process innovation were positively correlated to the corporate competitive advantage. Therefore, the result meant that the investment in the green product innovation and green process innovation was helpful to the businesses. This study argued that the businesses should cognize the correct value and positioning of the green innovation.Dr. Chen is the assistant professor in the Department of Business Administration in National Yunlin University of Science & Technology in Taiwan.

进口贸易、R&D溢出与中国制造业的就业变动   总被引:1,自引:0,他引:1  
本文利用1996~2005年中国制造业的面板数据,实证分析了进口贸易的R&D溢出对中国制造业的就业总量变动的影响及影响的部门差异。研究结果表明,考虑到进口贸易对国内制造业的R&D溢出效应后,中国制造业从发达国家的进口没有通过替代国内生产而减少就业,相反,进口贸易通过R&D溢出增加了整个制造部门的就业。由于技术进步的两面性和各部门要素密集度的不同,进口贸易的R&D溢出对就业的影响存在明显的部门差异。由于R&D投资回收期长、国内企业的技术吸收能力较弱,国内R&D投资和进口贸易的R&D溢出对就业总量的影响具有显著的滞后性。中国劳动力市场中的趋势效应、价格效应和规模效应的存在,使就业变动呈现动态调整的特征。  相似文献

在新一轮科技革命和产业变革背景下,新一代信息技术与制造业深度融合促使制造环节的创新功能凸显、增值能力增强和要素投入升级,进而提高了制造环节在全球价值链中的相对地位。新型制造技术的使用正在重构发达国家制造业的竞争优势,伴随着制造业回流,发达国家对全球价值链制造环节的参与程度有所提高。全球价值链调整导致中国制造业面临更加不确定的外部环境,同时又为制造业向价值链中高端攀升提供了机会窗口。中国应谨防过早“去工业化”,通过推动高水平对外开放、提高新一代信息技术与制造业融合创新能力、深入挖掘内需潜力、大力发展生产性服务业、深度参与全球经济治理等策略应对全球价值链调整。  相似文献
