The substance of this article was prepared for and delivered as the keynote address at the Joint Information Systems Committee’s Electronic Libraries Conference, “Information Ecologies: The Impact of New Information Species,” 2‐4 December 1998, York, UK. With a prefatory warning about the useful limits of metaphor, the ecological principles of equilibrium, opportunism, symbiosis and ecological succession are applied to the information economy. The potential implications for publishers, libraries, and new information types are explored.

Competition will affect the structure of an industry and the structure will, in turn, affect the behaviour of the firms involved. Two of the most important characteristics of the online information industry are the diversity of hosts and the range of databases offered by each one. The latter is a significant factor in searchers' choices of databases and consequently encourages hosts to compete by acquiring additional databases. This type of non‐price competition plays a key role as it is difficult to make accurate comparisons of the costs of using different hosts. Parallels are drawn with other industries in which competition is, or was, expressed chiefly in the form of capacity. The structure of one sector of the online information industry was investigated by applying Q‐analysis to data on medical databases and hosts. Changes over a three‐year period are identified and are interpreted using concepts derived from ecological niche theory. Finally, the question of what would constitute an optimum structure is considered and it is argued on the basis of an economic theory originally propounded by H. Hotelling that free competition would be unlikely to produce optimal results.

Although the supply chain (SC) competition concept has emerged during the past decade as the way firms will compete in future, there is scant academic research on actual mechanisms through which such competition can occur. The purpose of this paper is to proposes interaction as the means by which competition between supply chains may be undertaken.

The paper investigates a Swedish logistics center via case study methodology to develop the idea of interaction for SC vs SC competition.

Results suggest that interaction points along organizations ' supply chains may present enough breadth to assume a role in determining how SC vs SC competition may be played out in reality.

Interaction, as proposed here, implies an emphasis on all points at which supply chains meet to request goods and services, including various points where such supply chains converge, e.g. service providers, original equipment manufacturers, etc.

Most studies dealing with competition between supply chains fall short of exploring the link between theory and corresponding practice of this evolving competition mode. Such a link is provided with the use of logistics centers.

This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies.

This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context.

This review suggests the potential benefits of synthesizing the research concepts of organizational strategy and ecology through socio-ecological level analysis.

The briefing saves busy executives, strategists, and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

The purpose of this paper is to illustrate the emergence of a biological invasion and to explain the potential economic and social consequences on food chains. Straddling between ecology, social sciences, resource management and economics, invasion science is aimed at detecting, understanding and mitigating the impact of biological invasions on receiving ecosystems, including food ecosystems.

After a theoretical investigation about the main notions relevant for the invasion science, the authors practically review the kind of impacts deriving from biological invasions, mainly under economic, human health, ecosystem and biodiversity criteria.

The authors apply the DPSIR (Driving forces–pressure-state-impact-response) framework, originally developed in the context of European Environment Agency in this different context in order to assess the social, economic and environmental impacts of Invasive Alien Species (IAS). Responding to this emerging phenomenon, the European Union issues the EU regulation 1143/2014 which is the first strong act on invasive alien species.

Implications – Food chains are complex systems that have multiple interdependencies both endogenously and exogenously, such as food production, food transportation, food logistics, food distribution, and so forth. However, it is rarely conceived the impact of invasion systems on the dynamics of food chains, although food sustainability is in turn impacted by how effectively and efficiently the various interdependencies have been designed or are working.

Details the results of a monitoring exercise introduced in one local hospital to address the amount of time that patients spent waiting when attending outpatient departments in hospitals. Discusses whether a purely quantitative approach to quality can deliver the desired improvements. Argues that quality measures should incorporate more qualitative dimensions, including the tapping of patient perceptions of their experiences, before a claim can be made that reducing waiting times has improved overall quality. Also argues that the frequent use of the term customer in the quality literature receives critical attention when it is applied in the NHS. The fact that the term conflates the roles of consumer and purchaser makes analysis potentially difficult. Suggests that regarding patients as customers (in the manner of some traditional approaches to quality) is not a useful aid to analysis.

The purpose of this paper is to solve new pricing issues faced by low-carbon companies in the Yellow River Basin, which is caused by the change of key pricing factors in the mixed appliance background of Big Data and blockchain, such as product quality and carbon-emission reduction CER level (hereafter, CER level).

We choose a low-carbon supply chain with a low-carbon manufacturer and a retailer as our research object. Then, we propose that using the ineffective effect of the CER level and the quality and safety level to reflect the relationships among the CER level, the quality and safety level and the market demand is more suitable in the new environment. Based on these, we revise the demand equation. Afterwards, by using Stackelberg game, four cost-sharing situations and their pricing rules are analyzed.

Results indicated that in the four cost-sharing situations, the change trends and the magnitudes of the best retail prices were not affected by the changes of the inputs of the demand information and the traceability services costs (hereafter, DITS costs), the proportion about retailer's DITS costs undertaken by the manufacturer, the ineffective effect coefficient of the CER level and the quality and safety level and the cost optimization coefficient. However, the cost-sharing situations could affect the change magnitudes of the best revenues.

This paper has two main contributions. First, this paper proposes a demand function that is more suitable for the mixed appliance background of Big Data and blockchain. Secondly, this paper improves the cost-sharing model and finds that demand information sharing and traceability service sharing have different impacts on key pricing factors of low-carbon product. In addition, this research provides a theoretical reference for low-carbon supply chain members to formulate pricing strategies in the new background.

Aiming at the lack of explanatory power of traditional industrial organization theory in cross-border competition, by introducing the idea of ecological niche, the authors aim to explore the competitive situation of platform-based enterprises when they operate in multiple fields.

With the help of ecological niche theory, construct the niche width and niche overlap index of typical enterprises in the platform economy, and find out the advantages and the intensity of competition through comparative analysis.

In an environment of cross-border competition, large enterprises have significant competitive advantages, and the fierce competition is concentrated among medium-sized enterprises.

The conclusions of this paper not only provide new insights for explaining the phenomenon of cross-border competition in the platform economy, but also provide theoretical reference for the anti-trust enforcement practice in the platform economy.

The purpose of this paper is to propose a conceptualization of supply chain vs supply chain competition using the ecological niche approach. It suggests a probabilistic methodology for evaluating competition from time series data, using overlap in the utilization of services provided by critical providers as a source of competition.

Literature on ecological niche theory and competition is explored and given the uncertainty that surrounds the operation and management of supply chains, a probabilistic approach to the analysis of supply chain vs supply chain competition (via the Bayesian inference) is advocated. Simulated data are used to illustrate the methodology.

Should an area of overlap be identified, ecological niche theory provides a sensible approach to identifying the nature and extent of competition between supply chains. Applicability of the methodology is not limited to supply chain vs supply chain competition.

The data used for the analysis of competition between supply chains are computer generated and use a single niche dimension. Although this was done to merely test/validate the proposed model, the approach is somewhat oversimplified. However, the model is readily extendable to multiple niche dimensions.

The proposed approach offers a simple and straight‐forward method of estimating competition in general, and supply chains vs supply chain competition in particular. Attempts at using the niche theory of competition in this context are so far inconspicuous. Hence, approaching competition in this way contributes to furthering our understanding of competitive interaction especially in supply chains, whose prospect is yet to be pointed out in literature.

Knowledge input development and innovation implementation are new features of industrial technology innovation. The purpose of this study is to find the process of coordination and ecological spiral in the ambidextrous innovation of industrial technology.

To design the model of industrial technology ambidextrous innovation based on knowledge ecology spiral, an input-output model of knowledge for ambidextrous innovation and a spiral model of knowledge ecology were constructed based on an improved Lotka-Volterra model. Then, the equilibriums in different knowledge inputs and the spiral evolution of knowledge ecology were analyzed. Finally, the ambidextrous coordination mechanism of the core organization was revealed.

By coordinating the knowledge inputs and the knowledge ecology spiral, enterprises extend the R&D investments in the innovation chain, which will facilitate the knowledge inputs of the exploitative and exploratory innovation. Implementing the ambidextrous coordination in the technology innovation chain and the knowledge ecology chain has the advantage of promoting knowledge inputs, mobility and ecological spiral. Meanwhile, it can achieve the “multi-source, integration and coordination” development of industrial technology innovation.

The two-element innovative knowledge input coordination model and the knowledge ecological spiral model based on the improved Lotka-Volterra model are constructed, which extends the modeling way of the traditional knowledge input-output profit model. It is expected to reduce the amount of knowledge input of a single member and provide theoretical reference for improving the efficiency of knowledge input by constructing the inter-dependent regenerative and inter-generative knowledge interaction.
