Numerous innovative applications have been developed to utilise large quantity of fly ash generated at coal fired thermal power plants (TPPs) worldwide. However, this requires power plants to undertake the role of third-party innovation intermediaries, that is, commercialising technological innovations developed by others. As commercialising an innovation requires considerable resources, a well-considered selection and promotion are desired. The paper presents a strategic framework for commercialisation of fly ash innovations. Explanation for step-by-step implementation and generic pointers for strategy formulation for typical problems are suggested. The proposed framework is expected to assist coal-fired TPPs in formulating strategies to commercialise innovative utilisation of fly ash. The study contributes to scarcely addressed aspects of an open innovation paradigm, that is, challenges faced by third-party intermediaries.  相似文献

The use–make framework is employed to explain functional forms in production theory, including Cobb–Douglas and Leontief. Productivity and efficiency are interrelated by augmenting the framework with a linear program that determines the frontier output.  相似文献

ABSTRACT

At first glance, it seems that South Korea’s three fiscal systems (mid-term expenditure framework, top-down budgeting, and performance management) function well. However, each fiscal system operates separately and they are inefficient because they follow past practices. This article explains what the problems are and how to overcome them.  相似文献

Scholars have questioned the appropriateness of using a western‐centric framework to investigate corporate social responsibility (CSR) in emerging economies. This study assesses the appropriateness of using such a framework in one emerging economy—India. More specifically, the drivers of CSR and their impact on firm‐level CSR activity in the Indian context are investigated and compared with those in developed economies. Content analysis of 369 CSR policy statements of publicly traded Indian firms revealed the factors that drive CSR activities of Indian firms are similar to those found in developed economies. However, the ways firms respond to the drivers of CSR are surprisingly different in the Indian context, and these differences can be traced to attributes of the Indian socio‐cultural context. Implications and recommendations for future research conducted in India, and in other emerging economies, are offered.  相似文献

This paper examines how digital technologies facilitate business model innovations in the creative industries. Through a systematic literature review, a holistic business model framework is developed, which is then used to analyse the empirical evidence from the creative industries. The research found that digital technologies have facilitated pervasive changes in business models, and some significant trends have emerged. However, the reconfigured business models are often not ‘new’ in the unprecedented sense. Business model innovations are primarily reflected in using digital technologies to enable the deployment of a wider range of business models than previously available to a firm. A significant emerging trend is the increasing adoption of multiple business models as a portfolio within one firm. This is happening in firms of all sizes, when one firm uses multiple business models to serve different markets segments, sell different products, or engage with multi-sided markets, or to use different business models over time. The holistic business model framework is refined and extended through a recursive learning process, which can serve both as a cognitive instrument for understanding business models and a planning tool for business model innovations. The paper contributes to our understanding of the theory of business models and how digital technologies facilitate business model innovations in the creative industries. Three new themes for future research are highlighted.  相似文献
