The robust principal component analysis (RPCA) is a technique of multivariate statistics to assess the social and economic environment quality. This paper aims to explore a RPCA algorithm to analyze the spatial heterogeneity of social and economic environment of land uses (SEELU). RPCA supplies one of the most efficient methods to derive the most important components or factors affecting the regional difference of the social and economic environment. According to the spatial distributions of the levels of SEELU,the total land resources of China were divided into eight zones numbered by Ⅰ to Ⅷ which spatially referred to the eight levels of SEELU. 展开更多

The research analyzed social and economic development around Chao Lake as well as changes of water quality in Chao Lake and explored the relation- ships of local population and GDP with water chemical oxygen demand (COD), total phosphorus (TP), total nitrogen (TN), chlorophyll and eutrophication index. The re- sults showed that population around Chao Lake and GDP kept growing from 2001 to 2013, and water quality was improving. In addition, correlation analysis indicated that except of water eutrophication, GDP and population showed inverse correlation with other indices, demonstrating that water quality has been effectively controlled in Chao Lake recently. 展开更多

Data on discrete,isolated attributes of the marine economy are often used in traditional marine economic research.However,as the focus of urban research shifts from internal static attributes to external dynamic linkages,the importance of marine economic net-work research is beginning to emerge.The construction of the marine economic network in China’s coastal areas is necessary to change the flow of land and sea resources and optimize regional marine economic development.Employing data from headquarters and branches of sea-related A-share listed enterprises to construct the marine economic network in China,we use social network analysis(SNA)to discuss the characteristics of its evolution as of 2010,2015,and 2020 and its governance.The following results were obtained.1)In terms of topological characteristics,the scale of the marine economic network in China’s coastal areas has accelerated and expan-ded,and the connections have become increasingly close;thus,this development has complex network characteristics.2)In terms of spatial structure,the intensity of the connection fluctuates and does not form stable development support;the group structure gradually becomes clear,but the overall pattern is fragmented;there are spatial differences in marine economic agglomeration radiation;the radi-ation effect of the eastern marine economic circle is obvious;and the polarization effect of northern and southern marine economic circles is significant.On this basis,we construct a framework for the governance of a marine economic network with the market,the government,and industry as the three governing bodies.By clarifying the driving factors and building objectives of marine economic network construction,this study aims to foster the high-quality development of China’s marine economy. 展开更多

The exchanges between cities and counties in the northern slope economic belt of Tianshan Mountains(NSEBTM)are increasingly frequent and the economic linkages are increasingly close,but the spatial distribution of economic development and linkages among the cities and counties within NSEBTM is uneven.Therefore,it is of great significance to study the evolution of spatial-temporal pattern of the economic linkage network of cities and counties on NSEBTM to promote the coordinated and integrated development of the regional economy on NSEBTM.In this study,we used the modified gravity model and social network analysis method to analyze the spatio-temporal evolution characteristics of the economic linkage network structure of cities and counties on NSEBTM in 2000,2010,and 2020.The results showed that the comprehensive development quality level of cities and counties on NSEBTM increased from 2000 to 2020,its growth rate also increased,and its gap between cities and counties continued expanding.Both the spatial distribution patterns of the comprehensive development quality level of cities and counties on NSEBTM in 2000 and 2010 were presented as“high in the middle and low at both ends”,while the spatial distribution pattern of 2020 was exhibited as“high value and low value staggered”.The total amount of external economic linkages of cities and counties on NSEBTM showed an obvious upward trend,and its gap between cities and counties continued expanding,presenting a pattern of“a strong middle section and weak ends”.The direction of economic linkages of NSEBTM existed obvious central orientation and geographical proximity.The density of economic linkage network of NSEBTM increased from 2000 to 2020,and the structure of economic linkage network changed from single-core structure centered with Urumqi City to multicore structure centered with Urumqi City,Karamay City,Shihezi City,and Changji City,shifting from unbalanced development to balanced development.In the future,we should accelerate the construction of urban agglomeration on NSEBTM,cultivate a modern Urumqi metropolitan area,improve comprehensive development quality of the cities and counties at the eastern and western ends,strengthen the intensity of economic linkages between cities and counties,optimize the economic linkage network,and promote the coordinated and integrated development of regional economy. 展开更多

Sustainable livelihood security(SLS) is an integrating framework that encompasses current concerns and policy requirements for ecological, social, and economic dimensions of sustainable development. It carries particular importance for developing economies. This study intends to verify the relative status of SLS of the 30 districts in Odisha, which is a backward state in eastern India. In this study, a total of 22 relevant indicators relating to the three components of SLS—ecological security, social equity, and economic efficiency have been taken, based on various kinds of government reports. The principal component analysis(PCA) was used to ascertain the indicators and the importance of each of them to the corresponding component of SLS. The ecological security index(ESI), social equity index(SEI), economic efficiency index(EEI), and composite sustainable livelihood security index(CSLSI) of each district of Odisha were calculated through the min-max normalization technique. The results revealed that there are wide variations in SLS among the districts of Odisha. In this study, the districts are categorized into four levels based on the scores of ESI, SEI, EEI, and CSLSI as very low(<0.400), low(0.400–0.549), medium(0.550–0.700), and high(>0.700). According to the classification result of CSLSI, 2 districts are found to be in the very low category, 20 districts are under the low sustainability category, 8 districts are in the medium category, and none of the districts are found to be in the high sustainability category. The district of Sambalpur ranks the highest with a CSLSI score of 0.624. The bottom five districts are Gajapati, Bolangir, Nabarangpur, Kandhamal, and Malkangiri, having the CSLSI scores of 0.438, 0.435, 0.406, 0.391, and 0.344, respectively. The result of this study suggests that region-specific, systematic, and proactive approaches are desirable for balanced development in Odisha. Further, policy intervention is required to implement more inclusive tribal welfare policies. 展开更多

In this paper, we seek to analyze pre-electoral political language in Greece with the use of Social Network Analysis. For this analysis, we collected data from the pre-elections speeches of five political leaders from the 20th of September 2015 Greek general elections. We proceed to form, analyze and compare networks of words with an emphasis on financial vocabulary. Findings can provide interesting insights into how political leaders structure their speeches, evaluate important issues and use economic terms and political rhetoric, while different structural patterns can reveal the differences between political parties. Finally, we check whether the overall networks follow the general rules of real-life networks by belonging to the small-world or scale-free categories. 展开更多

World experience indicates the existence of significant imbalances in the development of countries.The problem of assessing the rational development of the regional and national economy is becoming urgent,since such assessments can prevent development imbalances across countries.The aim of this study is to elaborate a methodology to assess the countries’socio-economic development by integraring 12 modern indices of socio-economic development into the Composite Country Development Index(CCDI).The methodology of this research was based on a set of key indices that described socio-economic development level in four fields(social development,digital development,economic development,and environmental security)and then these indices were integrated into the CCDI.The study further applied factor analysis and R-Studio software to define the gaps of social and economic development in 59 selected countries using the trigonometric function of the angle sine.The correlation analysis confirmed the existence of a close interrelation among the studied countries.This paper noted that due to the emergence of new priorities,it is necessary to revise the assessment methodology of socio-economic development level and expand them to cover the decisive factors.This was confirmed by the results obtained,demonstrating various combinations of the development level in the four fields and their impact on the CCDI.The scientific contribution of this research is to form a methodology(e.g.,the CCDI)for evaluating the socio-economic development level of countries in the world. 展开更多

Purpose: This study analyzes the current status of institutional cooperation in economics and management (EM) and library and information science (LIS) in China.Design/methodology/approach: Based on the Chinese Social Science Citation Index (CSSCI) database, we constructed institutional collaboration networks in EM and LIS, and analyzed the collaboration characteristics through social network analysis.Findings: In the development and evolution of the collaboration network of institutions in humanities and social sciences, EM is always at the center. It has extensive cooperation relationships with other fields. The position of LIS has also become centralized, and its interdisciplinary cooperation has increased. For both EM and LIS, we observed "small-world" and "scale-free" networks, indicating full communication and mature development in both disciplines. Based on a comparison of two institutions in the two fields, we confirmed the comprehensive development in EM and the extensive information exchange in LIS.Research limitations: We collected data only from humanities and social sciences, but did not consider the connection between EM and natural sciences, or between LIS and natural sciences. In addition, the paper lacks analysis of institutional collaboration at the micro level.Practical implications: The paper provides insights into the institutional cooperation characteristics in EM and LIS in China.Originality/value: The paper offers a new perspective on the characteristics of institutional collaboration in China. 展开更多
