In the EURURALIS project, a chain of models was used to predict the changes in sustainable development indicators for European human well-being, ecology and economy issues, for four alternative scenarios of the future socio-economic development. This paper describes the biodiversity analysis of the project. Models based on general relationships between environmental factors and biodiversity loss were combined with socio-economic, land-use and environmental models to derive data that were integrated into an interactive tool for policy makers. The biodiversity analysis takes into account the effects of land-use change, climate change, fragmentation by major roads, area of unfragmented patches, nitrogen deposition, forestry and disturbance. Results show that biodiversity is projected to decrease between now and 2030 in most countries for all scenarios, indicating that it is unlikely that the EU will be able to fulfill its commitment to stop biodiversity loss by 2010. This is mainly due to urbanization and increase in stress factors, and outweighs the area increase of nature arising from land abandonment. Merits, limitations and uncertainties of this approach to biodiversity assessment are discussed.  相似文献

Innovation is characterized by uncertainties, high risks, large investments and late returns on investment which make it a complex process. This is particularly true for sustainable innovation where market forces alone cannot be relied upon to realize the desired transitions. Insight in the dynamics of such innovation processes is necessary in order to influence technological change toward a more sustainable direction. However, few instruments and indicators are available to assess the performance of emerging technological innovation systems. In this phase competition often takes place based on expectations rather than on technological performance. This paper therefore focuses on the expectation patterns of technological innovation systems in the exploratory phase through the analysis of the expectation dynamics of three emerging technologies in the field of sustainable mobility within the Netherlands: biofuels, hydrogen as a transport fuel and natural gas as a transport fuel. These technologies do not only compete with the current fossil-fuel based system but also with each other. We have collected over 5000 expectation events regarding these technologies for the period 2000–2008 and discuss the insights generated by the comparison of the observed expectation dynamics to theoretical patterns.  相似文献

The importance of project‐based firms is increasing, as they fulfill the growing demands for complex integrated systems and knowledge‐intensive services. While project‐based firms are generally strong in innovating their clients' systems and processes, they seem to be less successful in innovating their own products or services. The reasons behind this are the focus of this paper. The characteristics of project‐based firms are investigated, how these affect management practices for innovation projects, and the influence of these practices on project performance. Using survey data of 203 Dutch firms in the construction, engineering, information technology, and related industries, differences in characteristics between project‐based and nonproject‐based firms are identified. Project‐based firms are distinguished from nonproject‐based firms on the basis of organizational configuration, the complexity of the operational process, and the project management capabilities of the firm. Project‐based firms also differ with regard to their level of collaboration and their innovation strategy, but not in the level of autonomy. A comparison of 135 innovation projects in 96 of the firms shows that project‐based firms do not manage their innovation projects different from other firms. However, the effects of specific management practices on project performance are different, particularly the effects of planning, multidisciplinary teams and heavyweight project leaders. Differences in firm characteristics provide an explanation for the findings. The implication for the innovation management literature is that “best” practices for innovation management are firm dependent.  相似文献

This paper investigates the effects of having a separate innovation unit on exploration, exploitation, and ambidexterity in manufacturing and service firms according to traditional paradigms of the innovation management discipline that innovation units should be organized in a separate department. Many manufacturing firms have such a unit while few service firms do. This paper sets out to investigate the advantages of having such a unit for exploration, exploitation, and ambidexterity, and whether there are differences between manufacturing and service firms that could help explain why such units are present or absent. The literature suggests that a separate innovation unit has a positive effect on exploration and ambidexterity in manufacturing firms. However, the effect on improving operational activities, that is, exploitation, is unclear. If exploration and exploitation are two ends of a continuum, as the literature suggests, more exploration comes at the cost of exploitation. On the other hand, others have suggested the possibility of an orthogonal relationship, where a separate unit can simultaneously enhance exploration and exploitation. In this paper, the Dutch Community Innovation Survey (CIS) is used to investigate these relationships for manufacturing and service firms, with a question added to the survey regarding the locus of innovation within each firm, that is, mostly within a dedicated innovation unit or dispersed throughout the firm. Our findings show that a separate innovation unit increases exploration, exploitation, and ambidexterity in both manufacturing and service firms. It thereby provides support for the orthogonal view of ambidexterity. A separate unit enhances the ability to exploit and be ambidextrous equally in service and manufacturing firms, but has a weaker positive effect on exploration, and exploratory and ambidextrous performance in service firms. This finding implies that both manufacturing and service firms benefit from having a separate innovation unit, with the advantages being greatest for manufacturing firms. In service firms, such an innovation unit alone may not be sufficient, as such units are expensive to maintain, while they contribute less to ambidextrous performance than in manufacturing firms. Based on the latter finding, future studies should make a distinction between the ability to be ambidextrous in creating exploratory and exploitative innovations, and ambidextrous performance, the ability to gain financially from engaging in both types of activities simultaneously.  相似文献

Due to its environmental impact, the mobility system is increasingly under pressure. The challenges to cope with climate change, air quality, depleting fossil resources imply the need for a transition of the current mobility system towards a more sustainable one. Expectations and visions have been identified as crucial in the guidance of such transitions, and more specifically of actor strategies. Still, it remained unclear why the actors involved in transition activities appear to change their strategies frequently and suddenly. The empirical analysis of the expectations and strategies of three actors in the field of hydrogen and fuel cell technology indicates that changing actor strategies can be explained by rather volatile expectations related to different levels. Our case studies of the strategies of two large car manufacturers and the German government demonstrate that the car manufacturers refer strongly to expectations about the future regime, while expectations related to the socio-technical landscape level appear to be crucial for the strategy of the German government.  相似文献

Performance assessment of innovation projects is a central issue in innovation management research. Using existing literature, a model is developed to assess the performance of new product and new service development projects. In this model, project performance is defined as a combination of a formatively indicated operational performance construct and a reflectively indicated product performance construct. The validity of this model is tested based on a sample of 219 innovation projects assessed by innovation managers. Using only the innovation managers' responses, it is, however, not possible to distinguish between operational and product performance. The impact of common method bias and informant bias is subsequently assessed using a subsample of 128 of these 219 innovation projects that are assessed by the innovation manager and the project leader. These latter results show that operational and product performance are two distinct constructs. In addition, the multitrait–multimethod analyses show that especially the more abstract items of performance, such as the perceptions of quality, captured knowledge, competitive advantage, gained reputation, and customer satisfaction, suffer from random error and informant bias. Project leaders appear to be better informed to assess operational performance, while innovation managers are better in assessing product performance. The paper concludes with a qualitative comparison of several alternative performance models: the project performance model as derived from the literature, a similar (misspecified) reflective performance model, two stand‐alone models in which operational and product performance are assessed separately, and a mixed model that uses a combination of innovation managers' and project managers' data. Based on this comparison, it is advised to use either the stand‐alone models for operational performance and product performance or the mixed model whereby the project leader assesses operational performance and the innovation manager the product performance of an innovation project.  相似文献

Land-use changes rank among the most significant drivers of change in ecosystem services worldwide. The enhancement of important services such as biodiversity and carbon sequestration requires modifications in land-use that can lead to the decline in other ecosystems services. Targeting the most suitable areas for particular land-uses based on comparative advantages requires opportunity cost information across large regions. This is a demanding task because the input–output relations are ill-defined and determined by spatially heterogeneous operational and environmental conditions. To address this methodological challenge, this paper presents a two-stage semiparametric technique that enables multi-dimensional production possibility frontiers to be estimated from data provided by biophysical models. Specific advantages of the proposed frontier approach are its flexibility with regard to assumptions on the convexity of the production possibility set and its freedom from any separability assumptions for the input–output space and the space of the heterogeneous background variables. The method is illustrated for a case study of 18 Central and Eastern European countries. Results show that opportunity costs of changes in ecosystem services provision differ substantially between regions. Those areas having already relatively high levels of carbon sequestration have a comparative advantage in sequestering carbon. Opportunity costs of biodiversity are generally positively related with the level of biodiversity up to a turning point after which they are negatively related. To illustrate the policy consequences of the observed economies and diseconomies of scope we compare two management regimes to illustrate the potential gains from smart land management.  相似文献

A complex systems methodology to transition management   总被引:2,自引:2,他引:0  
There is a general sense of urgency that major technological transitions are required for sustainable development. Such transitions are best perceived as involving multiple transition steps along a transition path. Due to the path dependent and irreversible nature of innovation in complex technologies, an initial transition step along some preferred path may cut off paths that later may turn out to be more desirable. For these reasons, initial transition steps should allow for future flexibility, where we define flexibility as robustness regarding changing evidence and changing preferences. We propose a technology assessment methodology based on rugged fitness landscapes, which identifies the flexibility of initial transition steps in complex technologies. We illustrate our methodology by an empirical application to 2,646 possible future car systems.
