Recently, innovation processes towards sustainable development have received increasing attention in academic literature. This research introduces the combination of insights from innovation theory, sustainable development practice and small business characteristics to unlock new knowledge on factors that influence the translation of sustainable innovation within small and medium‐sized enterprises (SMEs) into practice. The sustainability themes and activities as described for large companies (i.e. in the sustainability reporting and management literature) were used as starting point in this study. It presents empiric results of the PRIMA Project conducted within the rubber and plastics industry (RPI) on sustainable innovation activities. It will show that many sustainable innovations are directed at the improvement of technological processes (eco‐efficiency) and to lower costs of production. These innovations can be seen as incremental. Companies with sustainability integrated in their orientation and innovation processes show value creation: the development of products new to the market (radical innovations) and cooperation with stakeholders. The PRIMA project shows that more insight in SME innovative characteristics and (e)valuation of sustainable innovation efforts provides opportunities to improve the sustainability performance of SMEs.

Providing health care involves a complex enterprise, and the trade‐off between quality and cost has been particularly stark compared to other industries. However, a recent focus on health sector supply networks is now producing significant innovations and improvements. This Special Topic Forum illustrates for the academic and practitioner community how health care supply chain research can benefit from our evolving understanding of supply chains and help push that understanding even further. We classify health care supply chain research into two broad categories—supply chain in health care and supply chain of health care—to set an agenda for future research.  相似文献

Recently, environmental management offers firms a source of competitive advantage in the marketplace. The development of environmental innovations is critical to the success of today's firms. Drawing on the Schumpeterian perspective of competition, this research examines how the perception of rival firms' green success influences a firm to pursue and produce environmental innovation through its green supply chain integration activities. Using survey data from 230 firms, a conceptual model is developed and tested using structural equation modeling. We find that the firms in our sample do perceive pressure from their competitors' success in environmental management activities, and thus take supply chain action to pursue integration activities. By differentiating incremental and radical environmental innovation, this study also reveals the role of three dimensions of green supply chain integration (internal, supplier, and customer integration of green product development) on incremental and radical environmental innovation separately. Specifically, findings suggest that green supply chain integration has a positive impact on developing incremental environmental innovation, while only customer integration has a significant positive impact on developing radical environmental innovation.  相似文献

Previous research shows that knowledge integration mechanisms (KIMs) mediate the cross‐functional collaboration‐product innovation performance relationship; however, this mediating effect seems to be rather weak. This study, in contrast, develops a moderated mediation (MOME) model to argue that such a mediating effect is moderated by product innovativeness. A sample comprised of 106 manufacturing firms is utilized in the analyses. A moderated‐mediation approach shows that the mediating effect of KIMs in the linkage between cross‐functional collaboration and product innovation performance varies by different perspectives of product innovativeness. From an industry (macro‐level) perspective, product innovativeness positively moderates the mediating effect of KIMs on product innovation performance; in contrast, such a moderating effect is not significant under a firm (micro‐level) perspective.

In this paper, purchasing innovation in the case of a distribution company is analysed from an interorganizational cost management (IOCM) perspective. In this company, purchasing costs play an important strategic role. This study suggests that a new practice of IOCM is necessary that is suitable for Korea's economic circumstances, including the family-controlled conglomerates (Chaebols) that dominate the entire economic system. The strong need to reduce purchasing costs within Chaebols and the Korean government policy that promotes joint growth of large and small firms are crucial factors in the successful implementation of IOCM practices. We also discuss the infrastructure that enables effective IOCM in the long term, thereby adding new findings to academic research in the area, and practical implications of this benchmark case for other companies planning purchasing innovations.  相似文献

In China, the balance gap of credit and saving account emerged in 1995, and its amount enlarged since then. By the end of Dec. 2005, with 28.7 trillion RMB saving balance and 19.5 trillion RMB gross credit account balance, the gap between saving and credit account was as large as 9.2 trillion RMB, which indicated a 67.8% of credit/saving ratio. Some believed this phenomenon was resulted from on one hand, the rapid growth of saving account; and on the other hand, relatively slower expanding of credit account. Some believed cooling down cash demand was behind the gap, while others claimed the balance gap caused dead capital and inefficiency service of saving account. In fact, the balance gap between credit and saving account might not necessarily relate to dead bank capital. And the phenomenon itself could not indicate the down-tendency of finance power that underlay economy. Nevertheless, it was liquidity not the balance gap should be regarded an index of capital situation in financial organizations. Therefore the balance gap between saving account and credit account could not be viewed as criteria against liquidity position. Solution of this problem should lay in boosting financial innovation among commercial banks, expending capital market and encouraging or permitting commercial banks as well as state-owed funds to enter share market and so on.  相似文献
