Innovation and imitation effects in Metaverse service adoption 总被引:1,自引:1,他引:0
This study examines the innovation and imitation effects in Metaverse service adoption. “Metaverse services” is a collective
term for services such as Augmented reality, Life logging, Mirror world, and Virtual world. Among them, Twitter, Google, iPhone,
and Secondlife (T.G.I.S) are the most popular services/products these days. To measure the adoption of these product/services,
the most commonly used are IP traffic and iPhone sales. Thus, in this study, we measured adoption by measuring changes in
the IP traffic volume of , , , and sales for iPhone during a 2-year period (from the first quarter of 2008 to the fourth quarter of 2009). To analyze this
time series data to reveal the innovation and imitation effect, we employed the Bass model. The results showed that each of
these services yields different innovation and imitation coefficient values. Imitation effects for all Metaverse services
are greater than innovation effects, and Secondlife’s innovation effects are larger than others. Also, iPhone sales, as a
measurement for information and communication technology (ICT) products, showed greater innovation effects than the other
services. Implications are drawn to explain these differences, such as, Googlemap’s imitation effects are based on network
externalities, while Twitter’s imitation effects are caused by the interactions of individuals; iPhone sales’ innovation effects
are explained by the timing of the measurement. 相似文献

The paper studies the effect of strengthening protection on R&D incentives in the context of process innovation. It shows that for non‐drastic innovations, that do not render the pre‐existing technology obsolete, the innovator might favor imitation if the expected royalty rate determined by the court is sufficiently high. Since imitation is discouraged for very high levels of patent protection, R&D investment is maximized for an intermediate level of patent strength. This finding provides a theoretical explanation for emerging empirical evidence questioning the effectiveness of strengthening protection on innovation incentives. It also serves as a justification for the imperfections of the existing patent system that allows for some infringement. 相似文献

The externalities produced by high-voltage transmission lines are multidimensional, may strongly depend on the local context, and are thus difficult to capture through standard environmental valuation exercises. We experiment a GIS approach to design a geographically stratified contingent valuation sample of the population resident in infrastructure corridors in a whole region. We estimate, by means of a binary choice logit model, the perceived marginal damage from impacts of power lines on human health, the landscape and the environment. Specific treatment is given to qualitatively different forms of impact, namely real estate depreciation versus diffused perception of damage, arising at different distances from the lines. The set of GIS-based variables (proximity to power lines, presence of other infrastructure, endowment of natural and built heritage and other local context variables) prove to be significant predictors in the utility function of resident households. Finally, we compute simulated values that combine information on individual’s willingness to pay, population density and the dimension of the considered corridor around the infrastructure, so as to generalize the outcomes of case-specific studies for use in policy choices such as infrastructure localization, undergrounding and negotiation of compensations. 相似文献

The All-Russian National Front (ARNF), created by Vladimir Putin in 2011, has rapidly increased its power and influence in policy-making. The Front has been used to monitor regional policies and to check both the effectiveness and loyalty of regional governors in carrying out central government policies. This article examines the main activities of the Front and its membership since its creation, and considers the implications for future economic development in Russia. 相似文献
