A PROCESS STUDY OF NEW TECHNOLOGY ADOPTION IN SMALLER MANUFACTURING FIRMS*

Based on longitudinal case studies of new technology adoption in five smaller Canadian manufacturing firms, this article develops an inductive process model that views the technology adoption process as a partially nested set of three parallel and interacting sub-processes that are different in nature: the strategic commitment process, the technology choice process and the financial justification process. These processes are themselves intertwined with other strategic decision processes in the firm, and influenced by a dynamic set of contextual elements that interact with one another over time. the study underlines the problems associated with a narrow conception of technology adoption as a ‘decision’while showing how various process models from the literature are useful in understanding different parts of the overall process of adoption     

Technology transfer as a learning and developmental process: an analysis of Norwegian programmes on technology transfer

This paper focuses on understanding technology transfer. The point of departure is to construct a model for transfer of technology based on organizational theory. The model identifies the transfer as a socio-technical learning and developmental process (TLD process). Technology is understood as a social construction where human choice and values determine the outcome. A successful transfer of new technology depends on a socio-technical change process, where the success is reached when the local company profitably integrates technology in its day-to-day operation.The TLD model is used as the basis for an empirical analysis of Norwegian programmes on technology transfer. This work is introduced by giving an overview of the literature evaluating the programmes. This literature, strongly influenced by qualitative methodology, does not give much insight into the basic elements of the TLD process. Therefore, the next step in the research is to investigate the models for the programmes in operation.The main conclusion is that no programme design is consciousiy based on understanding technology transfer as a socio-technical learning and developmental process. Firstly, technology is usually considered as a material artefact and not as a carrier of knowledge and cultural values. Secondiy, the traditional developmental model is bureaucratic and top-down. The intention is to furnish companies with technology and not to let the potential use of new technology be integrated into a planned learning and developmental process.The key point in this paper is to advocate that policymakers and managers of technology transfer programmes redesign their programmes to incorporate the important and necessary learning and developmental processes. If this is taken seriousiy, it will be possible to take full advantage of technology transfer as an important element in technology policy.

技术演化Logistic模型的扩展:多种技术创新演化的选择过程分析

典型的技术演化Logistic模型描述的是当存在两种新、旧技术的竞争时,单种创新的技术随时间的演化而扩散演化的轨迹,其缺陷是没有对多种创新技术同时作用进行分析。本文考虑一个改进的创新技术的扩散模型,拓展Logistic模型的解释空间,用技术适应度、新技术选择“尝试努力”时所运行的时间、平均尝试次数、“尝试努力”成功次数的平均概率等指标,来考察在一个固定的技术选择空间内,多种技术演化的随机寻优轨迹和寻优难度;从而在一定程度上为拓展技术选择空间引入新技术,不断进行技术创新提供理论解释。     

Defining and improving technology transfer business and management processes in university innovation centres

The complex and dynamic behaviour associated with technology transfer business processes combined with the technological risk involved in the participating small firms, has led to a lack of business process definition and improvement in this area. Furthermore, the embryonic firms are highly individualistic with differing needs for assistance and development. There may also be a tendency to provide infrastructure and basic services with an avoidance of business process definition and hence, improvement.The aim of this paper is to investigate how potential business and management inputs can be used to define and to suggest improvements for two key technology transfer business processes, namely the technology licensing process and the business building process.A stratified pathway process mapping approach is used. This research approach includes semi-structured interviews with University Innovation Centre small firms, focus groups with Innovation Centre stakeholders and best practice benchmarking.The findings indicate that a modified processual approach can be adopted to define key business processes within technology transfer. Using this approach it is possible to show where business and management interventions can most effectively be deployed in each process.     

Turning green subsidies into sustainability: How green process innovation improves firms' green image

Green process innovation has been seen as a key strategy for manufacturing firms to pursue sustainable development. Yet, how to help manufacturing firms eliminate bottlenecks when implementing green process innovation remains poorly understood. To address this issue, the current study, which is anchored in the government incentive perspective, examines the drivers, contingent conditions, and consequences of green process innovation by using the panel data of manufacturing‐listed firms in China from 2013 to 2017. The results present valuable findings: (a) green subsidies are positively related to two dimensions of green process innovation, namely, cleaner production technology and end‐of‐pipe technology; (b) both cleaner production technology and end‐of‐pipe technology are positively related to firms' green image; (c) a firm's cleaner production technology mediates the relationship between green subsidies and its green image; and (d) higher absorptive capacity strengthens the indirect effect of green subsidies on a firm's green image via cleaner production technology. Our results provide meaningful theoretical and practical implications by revealing the benefits of green subsidies through green process innovation by leveraging levels of absorptive capacity.

Environmental Accounting of Eco-innovations through Environmental Input–Output Analysis: The Case of Hydrogen and Fuel Cells Buses

The introduction of environmentally friendly innovations in both transport and energy sectors are included in the list of priorities of the European Union political agenda. This paper investigates the environmental consequences of the introduction of hydrogen and fuel cells technology in the European economic system by applying environmental input–output analysis and life cycle assessment tools. Hydrogen is produced through the reforming of natural gas and it is employed in fuel cells buses that offer transport services to final consumers. We have built three scenarios based on different assumptions on the final demand. We have shown the results for three impact categories: global warming, photochemical oxidation and acidification. The results suggest that the use of hydrogen in fuel cells buses is only environmentally desirable if accompanied either by the employment of renewable sources or by carbon dioxide capture, or both.

The technological choice decision making process: An example from Nigeria—the Kainji hydro-electric technology: A multi-purpose development technolog

This paper examines the technological-cum-economic/social/political criteria under which technological decisions are made. An example—The Kainji Dam hydro-electric technology—from Nigeria (a buyer of technology) is selected as a case study. The study shows the importance of socio-economic criteria in the process of making any technological choice decision. Nonetheless a close interplay of some political factors may mitigate purely the socio-economic considerations in the technological choice decision making process. This is evident in the choice of the Kainji Dam technology in Nigeria.
