  • 18. Innovation and Diffusion
    Hall on Diffusion 8 October 2003 18. Innovation and Diffusion Bronwyn H. Hall1 1 Hall on Diffusion 8 October 2003 18.1. Introduction In 1953, a young female Macaque monkey in the south of Japan washed a muddy sweet potato in a stream before eating it. This obvious improvement in food preparation was imitated quickly by other monkeys and in less than 10 years it became the norm in her immediate group; by 1983, the method had diffused completely. In 1956, the same monkey innovated again, inventing a technique in which handfuls of mixed sand and wheat grains were cast upon the sea, so that the floating cereal could be skimmed from the surface. Again, by 1983, this method of gleaning wheat had diffused almost completely throughout the local populations of Macaques.2 Besides the obvious fact that humankind does not have a monopoly on innovation, these examples illustrate a couple of things about the diffusion of innovations: first, when they are clearly better than what went before, new ideas of how to do things will usually spread via a “learning by observing” process, and second, the process can take some time; in these cases it took thirty years, and the life cycle of the Macaque monkey is somewhat shorter than ours (Kawai, Watanabe, and Mori 1992). Turning to the world of humans, it is safe to say that without diffusion, innovation would have little social or economic impact. In the study of innovation, the word diffusion is commonly used to describe the process by which individuals and firms in a society/economy adopt a new technology, or replace an older technology with a newer.

The key to the sustainable development of the construction industry is to popularize and promote the spread of green building technologies (GBTS) in the construction market. This study integrates the technology acceptance model (TAM) and the innovation diffusion theory (IDT) to analyze and construct the theoretical model of developers’ GBTS adoption behavior from three dimensions, including the individual factor, product factor and interface factor. This paper discusses the mechanism of GBTS adoption and diffusion in the construction market. The data are collected by questionnaire, and the structural equation model (SEM) is used for empirical analysis. The results show that the developers’ perceived usefulness (PU) and perceived ease of use (PEOU) of GBTS, developers’ innovativeness and sense of community at the individual level, competitive advantage at the product level, as well as government structural guarantees and relevant stakeholders at the interface level have a significant positive impact on the adoption of GBTS by developers.

  • A Summary of Diffusion of Innovations
    Les Robinson | Phone 0414 674 676 | Email [email protected] Web www.enablingchange.com.au | Blog http://enablingchange.posterous.com A summary of Diffusion of Innovations Les Robinson Fully revised and rewritten Jan 2009 Diffusion of Innovations seeks to explain how innovations are taken up in a population. An innovation is an idea, behaviour, or object that is perceived as new by its audience. Diffusion of Innovations offers three valuable insights into the process of social change: - What qualities make an innovation spread successfully. - The importance of peer-peer conversations and peer networks. - Understanding the needs of different user segments. These insights have been tested in more than 6000 research studies and field tests, so they are amongst the most reliable in the social sciences. What qualities make innovations spread? Diffusion of Innovations takes a radically different approach to most other theories of change. Instead of focusing on persuading individuals to change, it sees change as being primarily about the evolution or “reinvention” of products and behaviours so they become better fits for the needs of individuals and groups. In Diffusion of Innovations it is not people who change, but the innovations themselves. Why do certain innovations spread more quickly than others? And why do others fail? Diffusion scholars recognise five qualities that determine the success of an innovation.

Linking Resilience Theory and Diffusion of Innovations Theory to Understand the Potential for Perennials in the U.S. Corn Belt Abstract In the last 200 yr, more than 80% of the land in the U.S. Corn Belt agro-ecosystem has been converted from natural perennial vegetation to intensive agricultural production of row crops. Despite research showing how re-integration of perennial vegetation, e.g., cover crops, pasture, riparian buffers, and restored wetlands, at strategic landscape positions can bolster declining regional ecosystem functions, the amount of land area devoted to row crop production in the Corn Belt continues to increase.

  • Diffusion of Innovations 1 Diffusion of Innovations
    Diffusion of innovations 1 Diffusion of innovations Diffusion of Innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread through cultures. The concept was first studied by the French sociologist Gabriel Tarde (1890) and by German and Austrian anthropologists such as Friedrich Ratzel and Leo Frobenius.[1] Its basic epidemiological or internal-influence form was formulated by H. Earl Pemberton,[2] who provided examples of institutional diffusion such as postage stamps and compulsory school laws. The diffusion of innovations according to Rogers. With successive groups of consumers adopting the new technology (shown in blue), its market share (yellow) will eventually reach the saturation level. In mathematics the S curve is known as the logistic function. History In 1962 Everett Rogers, a professor of rural sociology published Diffusion of Innovations. In the book, Rogers synthesized research from over 508 diffusion studies and produced a theory for the adoption of innovations among individuals and organizations. The book proposed 4 main elements that influence the spread of a new idea: the innovation, communication channels, time, and a social system. That is, diffusion is the process by which an innovation is communicated through certain channels over time among the members of a social system. Individuals progress through 5 stages: knowledge, persuasion, decision, implementation, and confirmation. If the innovation is adopted, it spreads via various communication channels. During communication, the idea is rarely evaluated from a scientific standpoint; rather, subjective perceptions of the innovation influence diffusion. The process occurs over time. Finally, social systems determine diffusion, norms on diffusion, roles of opinion leaders and change agents, types of innovation decisions, and innovation consequences.
