This multistudy research examines the unit‐level relationship between promotive voice behavior and management innovation. Study 1 utilizes multisource data from 62 work units and reports that willingness to discuss ideas mediates the unit‐level relationship between promotive voice and management innovation. The results of Study 1 also show that the unit's available resources make the relationship stronger between promotive voice and willingness to discuss ideas. Study 2 employs a scenario‐based design to constructively replicate and expand the results of Study 1, utilizing a sample of 100 working adults. The results of the second study also show that resource availability positively moderates the relationship between promotive voice and willingness to discuss ideas. Furthermore, Study 2 shows that the indirect effect of promotive voice on management innovation through willingness to discuss ideas is stronger when more resources are made available to the work units. This moderated‐mediation effect is shown to be significant using two different operationalizations of management innovation. The implications for theory and practice are discussed. 相似文献

This paper constructed extended CDM model to study the effects of environmental regulation on industrial innovation and productivity based on the perspective of strong and weak “Porter hypothesis”, by using 28 manufacturing industry panel data of 2003–2014. The findings reveal that: (1) the impact of environmental regulation on R&D intensity lags behind. In the long run, environmental regulation intensity has a significant role in promoting R&D investment in manufacturing industry. (2) The R&D has a significant role in promoting the substantial innovation of manufacturing industry, and has a strong lag and continuity. However, the R&D intensity has no obvious effect on strategic innovation of manufacturing industry. (3) The substantial innovation doesn’t significantly promote the economic performance of manufacturing industry, but it has a significant role in promoting the energy performance of manufacturing industry, and the substantial innovation plays a significant role in promoting environmental performance in the long term. The strategic innovation significantly promotes the economic performance of manufacturing industry, and it inhibits the energy performance and has no significant effect on environmental performance in the short term. It can promote the energy performance of manufacturing industry, but significantly inhibit environmental performance in the long term. (4) Environmental regulation has significantly suppressed the substantive innovation and strategic innovation of manufacturing industry, and the weak Porter hypothesis has not yet been supported. In the short term, environmental regulation inhibits manufacturing economic performance, but it can promote energy and environmental performance. In the long run, environmental regulation promotes the economic and energy performance of manufacturing industry, but it inhibits environmental performance. The establishment of strong Porter hypothesis has a certain scenario. 相似文献

AbstractRe-distributed manufacturing (RDM), broadly described as manufacturing done at a smaller-scale and locally, could be beneficial to business and urban society through creating jobs, reducing the environmental impacts of production, and improving resilience to future disturbances. Consideration of RDM within a city-region requires the consideration of a wide range of issues – societal, technical, economic and environmental. This paper presents the results of a study into the potential for RDM to contribute to a sustainable, resilient city in the face of a range of expected future disturbances on the city and on manufacturing sectors. The study took an integrated assessment approach which incorporated the development of a conceptual framework; a ‘strawman’ causal loop diagram which was reviewed by participants in a workshop; and a stock and flow system dynamics model that represents our understanding about the structure and behaviour of urban manufacturing. Several key themes emerged: similarities between RDM and traditional manufacturing, availability of physical space for RDM to be done, achieving urban resilience through RDM by enabling responsiveness to disturbances, changes in environmental impacts from production, additions or losses in jobs, the competitiveness of local manufacturing, and skills and innovation for RDM technologies. Further work is recommended. 相似文献

This paper provides new econometric evidence on the determinants of eco-innovations by using multiple innovation indicators and by combining survey-based information and patent records at the firm level from two different time periods. We hypothesize that firms with a propensity to patent focus on future technological and market opportunities and do not directly or immediately react to incentives created by environmental policies. Based on negative binomial models, we confirm that eco-patents are stimulated by the expectation of creating technological advancement and new market opportunities. By contrast, energy cost savings can better or more easily be achieved when firms refrain from patenting and concentrate on non-patented innovations or adoption. Favorable framework conditions created by environmental policies and patent protection are also important for eco-patenting, but more in the longer term. Testing the validity of using self-reported eco-innovations, instead of patents, as the dependent variable in simple binomial probit models reveals that product eco-innovations as reported in the surveys are a relatively good proxy for eco-patents. Yet, for product eco-innovations, serving and enlarging current markets is another important reason to innovate. 相似文献

This paper first constructed a system to evaluate the innovation efficiency of industrial companies within Mainland China. Then, a principal component analysis (PCA) was performed to these indicators for dimensionality reduction, so as to figure out the technology innovation efficiency in these two phases, respectively. Finally, the overall efficiency of industrial companies in different regions was estimated and factorized via data envelopment analysis (DEA). The results showed that: (1) the efficiency of green technology innovation of industrial companies in China was relatively low as a whole, which mainly resulted from pure technical efficiency (PTE). Further, this huge gap continues to expand in these regions. And both PTE and scale efficiency (SE) in central and western regions leave much to be expected. (2) In the first phase of green technology development, when environmental factors were concerned, the efficiency was much lower than that without environmental considerations. Besides, the central and western regions were facing increasingly severe environmental problems, and there was a wide disparity in technology development efficiency among eastern, central, and western regions. (3) In the second phase of green technology commercialization, there were still more rooms for improvement in raising the efficiency of green technology innovation, and the efficiency in eastern, central, and western regions was ranked from highest to lowest. (4) Liaoning, Hebei, Heilongjiang, Xinjiang, Shanxi, Inner Mongolia, Yunnan, and Qinghai should focus on improving their technology; Jilin, Jiangxi, Anhui, and Guangxi should make their efforts to reduce resource redundancy; whereas Ningxia and Gansu should try to solve the above two issues. 相似文献

科技创新和低碳环保成为当今时代的主题,如何有效推动区域生态创新对于我国生态文明建设具有重要意义。本文基于低碳环保创新视角构建科技创新与生态环境复合系统协同度模型,在此基础上,选用2005-2013年中国三大城市群的面板数据对中国区域生态创新协同度进行测评,并运用计量经济模型从政府、市场、区域三个层面对生态创新协同度影响因素进行实证分析。协同度测度结果表明三大城市群生态创新协同度在[-0.05,0.3]之间震荡,协同度水平较低,区域科技创新与生态环境协同机制尚未建立。协同度增长速度存在空间差异,长三角增长速度最快,珠三角次之,京津冀增长最慢,原因在于河北省的生态创新协同度较低,京津冀区域存在内部发展不平衡问题。由于宏观经济环境和政府政策的影响,三大城市群协同度变化在时间上具有一致趋势。协同度影响因素分析表明政府环境规制、科技创新支持以及市场竞争程度对区域生态创新协同具有积极的推动作用,这说明政府增加环境规制强度和科技创新支持力度可以有效促进区域生态创新协同,市场竞争程度的提高也有利于提高区域生态创新协同水平。基于上述实证分析,本文认为政府应积极推动创新驱动战略和区域协同发展战略,加强环境规制和科技创新支持力度,建立生态创新产业链,鼓励绿色创新产业的发展,以科技创新拉动生态效益的改善,同时规范市场竞争秩序,完善技术交易市场,为绿色创新技术成果转化消除障碍,促进城市群形成生态创新协同机制并对全国各省市形成良好示范效应。 相似文献
