A Research on the Intra-Regional Accessibility and Economic Development in the Cardiff City Region

This paper investigates the relationship between intra-regional accessibility and economic development within the Cardiff City Region. Embracing the Capital City of Cardiff and its hinterland, this region is regarded as the economically most important one in Wales, and the key driver of Wale's current and future economic prosperity. Therefore, it is a significant problem how to fully realize its economic potential and its national role, and it is also controversial whether poor intra-regional accessibility is the biggest barrier to its further growth. This has been debated for years and provoked great research interest. By using a qualitative methodology, the paper identifi es that intra-regional accessibility is necessary, though not suff icient, for economic growth. It is necessary since it can increase the productivity of economic activities and infl uence the fi rms' location behavior, based on which this paper proposes some recommendations for economic development.

Ivory Coast Intra Regional Trade： The Role of Infrastructure and Economic Environment

Intra-regional trade dynamic can foster economic integration with a contribution of the lead economy. In that way, infrastructure and economic environment play an important role in expanding trade by reducing trade costs. This paper examines the role of infrastructure and the economic environment on Ivory Coast intra-regional trade. The study performs a transformed and advanced gravity model, using panel data over the period 1996 to 2013, modelling exports of Ivory Coast. The analysis shows experts towards the other member states of West African Economic and Monetary Union （WAEMU） depend significantly on the availability of transport and communication infrastructures developed as well as variables such as Gross Domestic Product growth, economic similarity within countries, Foreign Direct Investment （FDI） net inflows in Ivory Coast. Estimations point out that indeed, the level of economic growth in the other member countries, Foreign Direct Investment （FDI） net inflows in Ivory Coast, the number of mobile phone subscribers per 100 inhabitants in Ivory Coast and the proportion of paved roads, have a positive impact on Ivory Coast intra-regional trade.

Collaboration for radical and incremental innovation:The roles of intra-region and intra-group knowledge spillover

Knowledge spillover via collaboration is essential to innovation,with proximity being a vital factor.Nevertheless,little consensus has been achieved on which form of proximity is more critical for innovation.Instead of reaching a definitive conclusion,we highlight the potential of addressing the argument through the lens of innovation heterogeneity.This work thus contributes to current literature by integrating two forms of innovation,radical and incremental,into the discourse of geographical and organizational proximity in knowledge spillover via collaboration.Utilizing a dataset of patents from China’s listed firms between 2001 and 2017,we first categorize radical and incremental innovation according to the characteristics of knowledge combination,encompassing the familiarity of combined knowledge and maturity of combination ways.We further investigate the heterogenous effects of intra-region and intra-group knowledge spillovers,linked to geographical and organizational proximity in collaboration,on radical and incremental innovation.Empirical findings demonstrate that innovation relies on knowledge spillover both within groups and within regions.Moreover,intra-region spillover is essential for fostering radical innovation,while intra-group spillover only facilitates incremental innovation.Our findings provide both theoretical and practical implications,suggesting that multilocational enterprises should enhance their collaborator selection to leverage diverse knowledge spillovers,thereby fostering radical and incremental innovation in distinct ways.

Land Economic Density in China:Regional Differences and Influencing Factors

With the help of the Theil index,this paper analyzes the regional and intra-regional disparities in the Land Economic Density(LED)of the provincial-level regions in China from 2008 to 2017.The Pearson correlation coefficient is also employed to reveal the relationship between influencing factors and the LED of the empirical regions,so as to further identify differences in the LED of different regions.The paper finds that firstly,the average LED on the national scale has grown gradually from about 787 million yuan/km^(2) in 2008 to around 1,396 million yuan/km^(2) in 2017.Secondly,the intra-regional disparity in LED shows a decrease trend.Conversely,the regional disparity in LED has increased year by year.Thirdly,the LED of different regions has different correlations with their influencing factors.Finally,both education and technology input have a significantly positive correlation with the LED,and a negative correlation with urban-rural consumption ratio,which indicates that improving the education and technology input could balance regional development and narrow the development gap between urban and rural areas.
