Purpose: Recent years have seen a substantial increase in academic interest in social capital and innovation. Nonetheless, the bibliometric and visualization study on this subject is inadequate. This study aims to analyse the leading trends in literature that have connected social capital with innovation over the past few decades.Design/methodology/approach: This study attempts to provide an overview utilizing various bibliometric techniques combined with assorted themes and data extracted from the Scopus database. Results based on 716 documents reveal not only the principal modern trends but also the evolution of these scientific production developments.Findings: Results based on 716 Scopus indexed documents reveal the trends and trajectories as well as specific topics, journals and countries of social capital and innovation research Furthermore, this study offers an overview of trends and trajectories, as well as a visual and schematic framework for further research on this subject.Originality/value: Since there is lack of analyses the bibliographic data on social capital-related innovation, so this study is a unique contribution to the literature as complement. This may benefit researchers in identifying current trends and prospective study areas, as well as assisting future authors in conducting more efficient studies.

In recent years, the interest in academic research in the field of the value chain has increased rapidly. However, there is a lack of bibliometric and visualization research on this subject. This paper aims to analyze the main trends of the value chain in multidomain-related literature in the past decade. Thus, we used bibliometric 2002 documents data from the Scopus to generate figures like the trend, co-occurrence and proportion of the value chain by using Rstudio and VOSviewer. The results not only explained the main modern trends under the time series, but also showed the evolution of the development of the theme of the value chain. Additionally, the paper also determines the impact of the value chain in different journals and documents and analyzes the impact of themes, countries and keywords on the publication of the value chain literature. After identifying the most popular themes and keywords in the past decade, we predicted the trend and direction of future value chain research. Due to the lack of literature for data analysis on value-chain-related innovation, this study is a unique contribution to the literature on the measurement method as a supplement. This study also provides a visual and schematic framework for the relevant research in the field of the value chain and summarizes the trend and trajectory. This may help researchers understand the current trend of the research on the value chain and grasp the future research direction.

Song, L.; Zhang, L., and Wang, S., 2020. Population employment environment of coastal urban population and economic structure growth of coastal cities. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 134–138. Coconut Creek (Florida), ISSN 0749-0208.Because the problems in the economic system of coastal cities are becoming more and more prominent, in order to promote the sustainable development of the economic structure of coastal cities, this paper puts forward the impact analysis of the population employment environment and economic structure growth in coastal cities. First, describe and analyze the population employment situation and demographic factors that affect the growth of economic structure in coastal cities. Then, through discussing the development of relevant economic elements in coastal cities, master the overall situation of population employment and economic structure growth in coastal cities. Using the modified Cobb-Douglas production function model and 10-year data, this paper makes an empirical analysis on population employment and economic indicators in coastal cities, and concludes that the results of coastal cities, continental cities and desert cities all belong to increasing remuneration type.
