The processes of diversification are reviewed through the prism of not only the views and approaches developed within the framework of modern evolutionary economic geography but also institutional economics. It is shown that the state and dynamics of diversification processes in the Asian Russia are determined by the peculiarities of the transformation of the country’s economy as a whole during the transition from the system of centralized planning and management to a system based on market principles of interaction between economic agents. The role and importance of previously formed assets and implemented solutions – especially in the infrastructure sphere and previously created production structures – are extremely high. Without taking into account the peculiarities of space – the significant distances between different productions that are links in the value chain – the transformation of the economy leads to a narrowing of the spheres of economic activity and subsequent de-industrialization. According to the authors, the transition to the evolutionary process of economic diversification of the vast macroregion is impossible without a balanced public industrial policy and policy in the field of nature and subsoil use. The analysis of the processes of diversification / de-industrialization is supplemented and expanded within the framework of the cognitive analysis of possible directions and conditions affecting them. The authors offer a set of fundamental measures and steps, that allow, in their opinion, moving from ‘extra-regional’ causes of diversification to augmenting the role and importance of local and internal factors and conditions","PeriodicalId":54733,"journal":{"name":"Networks & Spatial Economics","volume":"40 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82464372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This model is formulated as an equivalent integer programming problem by predefining the transportation corridors and passengers' OD pairs. A branch-and-cut algorithm is proposed to find a non-inferior solution set. We also conduct trade-off analysis between efficiency, effectiveness and equity under each deployment strategy using the modified Gini coefficient method. The effectiveness of the proposed model and solution algorithm are tested with rapid transit network of the Beijing Capital International Airport. Results show that among the three common network topologies, including star, tree and finger, the passenger demand coverage and travel time reduction per unit cost under star topology outperform the other two topologies. As for finger topology, the performances of the passenger demand coverage and travel time reduction are the best among the three, but the cost is the poorest. In addition, the trade-off analysis shows that the solution whose objective is to maximize passenger demand coverage has a higher efficiency and a lower unit cost than the solution whose objective is to reduce travel time. However, the latter has a higher level of equity, especially for the medium and low-cost solutions. The proposed method in this study can help the decision makers to design effective landside rapid transit networks for large airports to improve the service level.","PeriodicalId":54733,"journal":{"name":"Networks & Spatial Economics","volume":"22 4","pages":"767-801"},"PeriodicalIF":2.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9244575/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40482461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All users in social media platforms are modeled as nodes in one of five compartments of a directed random graph: susceptible, hesitating, infected, mitigated, and recovered (SHIMR). The system is expressed with edge-based formulation and the transition dynamics are derived as a system of ordinary differential equations. We further allow individuals to decide whether to share, or disregard, or debunk the rumor so as to balance the potential gain and loss. This decision process is formulated as a game, and the condition to achieve mixed Nash equilibrium is derived. The system dynamics under equilibrium are solved and verified based on simulation results. A series of parametric analyses are conducted to investigate the factors that affect the transmission process. Insights are drawn from these results to help social media platforms design proper control strategies that can enhance the robustness of the online community against rumors.","PeriodicalId":54733,"journal":{"name":"Networks & Spatial Economics","volume":"22 4","pages":"831-854"},"PeriodicalIF":1.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9245889/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40586921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Does the direction and magnitude of subsidies impact depend on farm specialization? To address this question, I use farm-level data from Amur region in the Russian Far East for 2010–2014. The data set includes farms inputs and output as well as state subsidies and degree of farm specialization. The latter is defined as the share of crop production in total farm revenue. The sample of farms is not random but includes almost the entire set of corporate farms in the Amur Region. Using the data, I estimate the production function that allows me to study the relationships between total factor productivity (TFP), farms specialization and state subsidies. To test whether farm specialization moderates the impact of subsidies on TFP, an interaction term between specialization and subsidies was included in the model. So, I study how the marginal effects of subsidies change conditional on degree of specialization. My findings support the heterogeneous effect of subsidies on TFP depending on the degree of farm specialization. High degree of specialization on livestock production is associated with negative effects of subsidies on TFP, while I don’t fine a statistically significant connection between subsides and TFP for farms specializing on crop production. The research contributes to the discussion about the effects of state supports and subsidies on agricultural development and productivity in Russia and particularly in the Russian Far East","PeriodicalId":54733,"journal":{"name":"Networks & Spatial Economics","volume":"40 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84045958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The transit of goods from the central and western provinces of China to the ASEAN countries, relying on the central logistics center of the Chengdu-Chongqing Economic Circle, will pass through the Pan-Asian Railway and Highway Network, that will be built with the help of Chinese companies. As well as by sea transportation of goods from the ports of Beibu Bay and Yangpu Port in Hainan Province. The development and ratification of the Comprehensive Regional Economic Partnership Agreement, which has become a generator of growth in the volume of foreign trade between China and the ASEAN countries, Japan, and the Republic of Korea, required adequate measures to ensure regional cargo transit. In this regard, a large national logistics operator has been founded in China, and there are plans to build a financial center in Chongqing by 2025, which will become an important platform for further development of cross-border payments in yuan and deepening financial cooperation with ASEAN countries. The new corridor allows to significantly reduce the time and cost of cargo transportation from the western provinces of China to the ASEAN countries. In the future, with the connection of the Eurasian land-sea route and the Kashgar-Gwadar Port railway (as part of the development of the Chinese-Pakistani economic corridor) through the Economic Circle of Chengdu-Chongqing, it also allows to ensure the access of the central and western region to the markets of Europe, Africa, the Middle East, South and Central Asia.

The present study aims to investigate the connectivity between spatial competitiveness and resilience in Europe and seeks to design an operational framework for concerted strategies of competitive and resilient regions. To assess the linkage between resilience and competitiveness, we have developed a new measure, viz. the Resilience and Competitiveness Index (RACI) as a function of two constituent sub-indices: Resilience and Competitiveness. This approach is tested on the basis of detailed data on European regions. The empirical results from 268 EU NUTS2 regions offer a solid anchor point for the proposed operational framework for concerted development strategies of competitive and resilient regions. Our research distinguishes and proposes several systematic types of concerted regional strategies according to the performance of a region measured by Resilience and Competiveness sub-indices. A key result of the study is the design of an operational constellation for strategic regional policy evaluation, with a major added value for policy- and decision-making purposes. The use of official data from Eurostat and of standard indicators in our research assures continuity and consistency with the official Regional Competitiveness Index (RCI) classification and measurement, so that policy makers are able to compare the performance of their regions over time and to develop proper concerted strategies accordingly. The clear evidence of a connectivity between regional competitiveness and resilience may help to develop a governance approach that balances competitiveness (mainly represented by productive assets) with resilience (mainly represented by sustainability and ecological awareness) and thus to deal with the complexity in socioeconomic systems.","PeriodicalId":54733,"journal":{"name":"Networks & Spatial Economics","volume":"22 3","pages":"607-634"},"PeriodicalIF":2.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s11067-021-09522-z","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25370982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
