We used 11 variables including macroeconomic variables and regional variables of Seoul and Busan from the 1st quarter of 2007 to the 4th quarter of 2010, and found out that Seoul's best model consists of fluctuation of land price (Seoul), consumer price index, market interest, mortgage rate, and CD rate, and Busan's best model consists of nominal GDP. In addition, we derived top ranked model with Occam's Window. With selected models and AR model, we predicted housing trade price index from the 1st quarter of 2011 to the 4th quarter of 2014, and both BMS and BMA showed better performance in prediction than AR.

In times like these, the role of knowledge, which is essentially the driving force of innovation and thus promoting technological change and economic growth, is shifting due to new labour market conditions. The present study aims to explore how processes of local knowledge bases have been altered in this transformative environment and how these have impacted on local employment growth. The investigation considers three different knowledge bases in conjunction, incl. knowledge size, knowledge creation, and knowledge application. The study is based on an econometric analysis of a panel of 94 France NUTS-3 regions covering the period 1985-2015, utilizing patent data from European Patent Office (EPO) Statistical Patent Database (PATSTAT), and regional data from European Regional Database (ERD). The result shows that the role of knowledge for employment growth has indeed changed towards more specialized inputs in applications while the importance of greater knowledge size remains still important.

Building upon the theoretical model proposed by Basu et al. (2003), we include several features to account for two important aspects of ICT: complementarity with other intangibles, and externalities among different sectors. We propose several measures of externalities, distinguishing between foreign and domestic spillovers, and inter- and intra-industry spillovers. We focus on domestic spillovers, and compare a standard measure with a measure computed by weighting the ICT capital of other industries with bilateral sectoral trade. We find that results are affected by the way spillovers are measured. Evidence in favour of domestic externalities is only found when using the second measure, meaning that spillover effects only exist among industries that are connected via international trade. Foreign spillover effects are not detected.

In order to produce novel and valuable knowledge, it is advantageous, perhaps vital, to rely on insights gained from prior research efforts. Those knowledge spillovers (KS) provide the rationale for sustained economic growth and produce unique place-based knowledge spaces. Due to the spatial embeddedness and stickiness of knowledge, most investigations mainly pay attention to the localized nature of KS, but what about those spillovers from other jurisdictions, or perhaps even from across the globe? To analyse the role played by international KS, the present study investigates to what extent international KS shape the evolution of the UK science and technology space. The first step involves creating knowledge spaces following the methodology outlined by Kogler et al. (2013; 2017) for the period 2006–15. Subsequently, we are following the paper trail of publications and patents developed by UK authors and inventors to depict to what degree international KS in specific science and technology domains have contributed to the production of novel knowledge in the UK. The results indicate that four out of five citations made in publications and patents in the UK are the works of authors and inventors residing elsewhere. This has important policy implications considering recent tendencies to curtail trade and the free movement of labour, all of which contribute to the diffusion of knowledge.

Using Web of Science publication data from European regions for the period between 2008 and 2017, this study examines, first, the impact of scientific collaboration on novelty of research. Here, five levels of collaboration are considered for each article-country, three levels of regions, and institutions, and novelty is measured with keywords information. Second, we investigate both the effect and moderating effect of research funding on novelty. Our findings show that there is a negative and significant relationship between scientific collaboration and novelty. Furthermore, funded papers show lower novelty than the unfunded, but funding does have a significant moderating effect on the relationship between collaboration and novelty. This study contributes by linking diverse levels of collaboration and funding sources to article's novelty and thus extending the scope of bibliometric research of publications.

Due to social distancing, the untact service area is expanding not only to shopping but also to online learning, home training, and telemedicine, and untact services are expected to expand to more diverse areas in the future. This study investigates four types of untact services: online lectures, online meetings related to work and study, online seminars, and online performances, and the effects of concerns about untact services on the intention of use have been examined using a path analysis model. As a result of the analysis, the perceived usefulness had a positive effect on the user’s continuous intention to use untact services. However, depending on the type of untact service, it can be confirmed that the factors that affect the intention to continue using the service differ from each other. Practitioners...
