The identification, logic and enlightenments of intra-urban place communities in China

Spatial agglomeration phenomena on the earth permeate in various fields of the natural and human world, yet their researches in human society are relatively few with the focus mainly on the economic concept of “industrial clusters”. Precise quantitative descriptions, in-depth logical analyses and proper application approaches for urban planning are lacked in various intra-urban spatial agglomeration phenomena. By using over 10 million POIs in the mainland China, 18 grid network models with two varieties of spatial relationships (co-location/adjacent) are constructed in this article. 23 typical place communities are extracted based on complex network analysis, and four types of agglomeration driving forces are summarized. A comprehensive demonstration displaying the application process of co-location/adjacent place matrices in auxiliary decision of the implanted place types is carried out with the example of the revitalization project of Taoxichuan Area in the city of Jingdezhen.

The Ecosystem Services and Green Infrastructure: A Systematic Review and the Gap of Economic Valuation

This study was conducted to determine the trends at the intersection of studies made on green infrastructure and ecosystem services, which have frequently become preferred in establishing urban−green space relationships in global research. Green-related concepts have frequently been used from past to present in order to neutralise the increasing pressures on urban dynamics resulting from rapid urbanisation. Green corridor, green belt, green structure, and green finger/hand concepts have been used to provide recreational opportunities, protect nature, and keep urban sprawl under control. For the last decade, however, in addition to the traditional green concepts, green infrastructure (GI) and ecosystem services (ES) have been preferred in contemporary urban planning, as they enable the integration of the ecological concerns of the landscape and the socio-political perspective. The aim of this study is to detect the trends of the green infrastructure and ecosystem services association, and to reveal these trends in the common area with the bibliometric mapping method. The economic concept and its analysing use at the intersection of green infrastructure and ecosystem services were explored with VOSviewer using the Scopus® database. Furthermore, the number of documents, which initially began with around 39,719 studies, was reduced by filtering through systematic reviews, to only three documents that met the economic valuation criteria. In this way, a lack of economic analyses, creating a serious research gap within the framework of green infrastructure and ecosystem services, was quantitatively determined.

Assessment of Oil Rent of the Russian Federation

The article presents the position of the author, relating to such an important economic concept as oil rent. The oil rent of the country, estimated in the world economic space, is determined and considered. A mathematical model is presented that allows calculating such rent using available statistical information. The method of obtaining initial data is described and the results of specific applied calculations are given. The interpretation of oil rents as super-profits of oil companies, established in economic science, affects, according to the author, only a part of the economic benefits that the country receives by developing its oil fields. If we consider such deposits as a natural gift, then it is possible, according to the author, to estimate the full size of this gift only as a result of comparing the real situation with the virtual one, in which there are no such deposits or they are, but are not exploited. The result of such a comparison is considered in the article as the oil rent of the country, estimated in the world economic space. As an illustration, the results of calculations of the oil rent of the Russian Federation for 2011, 2013, 2015 and 2018 are given. А brief analysis of the results obtained and their dependence on external economic circumstances is given. For the purpose of comparison, the calculation of the oil rent of Saudi Arabia for 2018 is given.

PREDATORY PRICING: SINGLE- FIRM DOMINANCE, EXCLUSIONARY ABUSE AND PREDATORY PRICES (PART 3)

Important pronouncements of legal principle were recently made by the Competition Appeal Court and Constitutional Court on the determination of predatory pricing under section 8 of the Competition Act 89 of 1998. These pronouncements must now be seen in the context of the subsequent commencement of the Competition Amendment Act 18 of 2018. In light of these developments, this three-part series of articles evaluate the law relating to the economic concept of predatory pricing under the Competition Act. In this context, the crucial elements of dominance and abuse are also discussed. The first in this series of three articles critically evaluated the law on the determination of single-firm dominance under section 7 of the Competition Act. The second article discussed the basic forms of abuse, the meaning of abuse, tests that have been developed to identify exclusionary conduct, the criticism of the traditional theory of predatory pricing, the main strategic economic theories of predatory pricing and non-pricing theories of predation. This article focuses on the law of predatory prices under section 8(1)(c) and 8(1)(d)(iv) of the Competition Act. Pursuant to section 1(3) of the Competition Act, when interpreting or applying the Competition Act, appropriate foreign and international law may be considered. This is complementary to section 1(2)(a), which directs that the Competition Act must be interpreted in a manner that is consistent with the Constitution and which gives effect to the purposes set out in section 2. In light hereof and where appropriate, the South African position is mainly compared with the position in the European Union and the United States.

Resource Regions and the Transition to Sustainable Knowledge-based Development: Escaping the Resource Curse?

According to the economic concept of the “resource curse”, the specialization of countries and regions in the extraction of minerals can have a negative impact on their long-term economic development. The authors of the article propose, that this influence can significantly slow down the transition to development based on knowledge. The article tested this hypothesis using the dynamics of indicators of the knowledge-based economy the group of resource regions of Russia. Of the 12 resource regions of Russia, only two successfully form the knowledge-based economy - Tomsk Region and The Republic of Tatarstan. These regions had a developed education system and research infrastructure even before the discovery of oil here in the 1940s-1960s. For the rest of the resource regions, there is a large lag behind the leading regions of the knowledge economy in Russia, which does not significantly decrease during 2005-2019. At the same time, these regions did not have a developed scientific and educational base by the beginning of the active industrial development of natural resources on their territory. Thus, the formation of the knowledge-based economy in resource regions is strongly influenced by both the resource curse and path dependence effects. The absence of structural economic policies in the regions that are rich in natural resources will hinder their transition to knowledge-based development.

Evaluation of a Healthy Checkout Lane “Nudge” on Grocery and Convenience Store Sales of a Price-Promoted Nutritious Food

Grocery store intervention trials, including trials testing behavioral economics “nudges,” may change food-purchasing behaviors and improve diet quality. This study aimed to design and evaluate a grocery store healthy checkout lane “nudge” intervention on sales of a targeted healthy item. We conducted a randomized controlled trial based on the behavioral economic concept of cognitive fatigue and the marketing concept of impulse buying. Six grocery stores from one North Carolina-based chain were randomized to the intervention (n = 3) or control (n = 3) condition. Researchers tested a 4-week healthy checkout lane intervention, in which intervention stores moved 6-ounce cans of peanuts to the cash registers. Cashiers were instructed to upsell the peanuts to all shoppers at checkout. While not a component of the intervention, the retailer decreased the price of the peanuts from $1.99 to $1.50 during the first 2 weeks of the intervention. Fidelity to the checkout display was high. Fidelity to the upsell was low. The main outcome measure was aggregated store-level sales of the promoted peanuts for 4 weeks before the intervention and during the 4-week intervention period. On average, sales increased by 10 units/week in intervention stores (5.83 vs. 15.83 units, p = .04) with no significant change in control stores (1.42 vs. 1.17 units, p = .64). The difference (10 vs. −0.25 units, p = .02) was likely due to displaying the peanuts at checkout combined with the price promotion. Larger randomized controlled trials should examine whether healthy checkout lane interventions are effective “nudges” for promoting purchases of healthier foods in grocery stores.

PERSONNEL DEVELOPMENT OF INNOVATIVE-ACTIVE ENTERPRISE AS AN OBJECT OF MANAGEMENT IN INCREASING COMPETITIVENESS

Personnel development is a complex economic concept, which is proposed to be understood as the management activities of the enterprise, which involves the formation and increase of quality professional, social, personal characteristics of staff to ensure the current and strategic goals of the enterprise. In addition, staff development is a process consisting of a series of successive stages. In the structure of personnel development of the enterprise it is expedient to separate professional, social, personal directions which have various tasks, and at the same time are elements of a uniform complex of actions having common methods of realization of tasks. The basis of development is professional development, which is proposed to understand the process of formation and increase of professional potential of employees of the enterprise, due to the acquisition of qualitatively new characteristics for the maximum realization of human abilities in professional activities. The peculiarities of forming an effective management system of development and use of the enterprise’s personnel are investigated. Some measures to improve the effectiveness of the management process of development and use of personnel are proposed. The scientific approaches concerning formation of the mechanism of management of development and use of personnel are considered. The task of personnel development management of an innovatively active enterprise is to ensure compliance of quantitative and qualitative characteristics of personnel with the existing needs of the enterprise at the moment; development of innovative potential of the enterprise personnel. The innovative potential of an innovatively active enterprise should be understood as objective opportunities to maximize the intellectual potential of employees to achieve goals, as well as a set of tools, sources, opportunities and abilities, the use of which is aimed at solving any problems in innovation. The support system contributes to the realization of the goal of personnel development management of an innovatively active enterprise, by providing the necessary resources and creating the appropriate prerequisites.

The Scale, Logic and Structure of Intra-urban Place Communities Based on Place Niche Theory

Spatial agglomeration phenomena on the earth's surface permeate in various fields of the natural and human world, yet their researches in human society are relatively few with the focus mainly on the economic concept of "industrial clusters". Precise quantitative descriptions, in-depth logical analyses and overall systematic explanations are lacked in various intra-urban spatial agglomeration phenomena. Using over 10 million POIs in the mainland China, 18 grid network models of 9 grid scales based on two kinds of spatial relationships (co-location/adjacent) are constructed in this article. 23 typical place communities are extracted based on complex network analysis, and four types including 11 sub-categories of agglomeration patterns are summarized. Drawing on the concept of "ecological niche", we further propose the theory of "place niche" and analyze the logic and structure of intra-urban place communities within its framework. This study extends the spatial scales and dominating factors of the agglomeration phenomenon research.
