The study aims to present variability in the population of individual size classes of Polish cities in 1950-2018, its determinants and consequences for the formation of the settlement system. The application of quartiles as the basic statistical measure allowed identifying which parts of particular size classes of cities had the greatest impact (progressively or regressively) on changes in the settlement system. In this respect, strong dynamics of the upper quartile of Polish cities, lasting until the end of the 1970s, becomes apparent. In the 1980s, the dynamics of the upper quartile of large cities showed a shift during development waves in comparison to the culmination of these waves for medium-sized cities. However, since the end of the 1980s, there has been an increasing role of the lower quartile in determining the direction of changes in the size structure of cities, especially in medium and small cities.

Rural areas cover the largest part of the territory of Lithuania as well as that of the whole Europe. Rural settlements are also the most abundant category in the settlement system of the country. Therefore, their social, economic, and cultural viability- as well as ecologic sustainability playan important role striving towards the goals of sustainable development. During the last years projects promoting various aspects of sustainability are implemented not only in large cities and towns, but also in smaller municipalities, nevertheless many rural settlements still are not influenced by these trends. The tendency of decrease of the population of the country, emigration, migration of young and qualified persons to larger cities and towns, poverty and unemployment cause the threat to the most fragile elements of the rural settlement system, such as steadings, manor residencies and ethnographic village settlements. In order to stop these processes it is necessary to search for means to sustain the social and economic viability of rural settlements. During the last decade significant role of cultural heritage in implementing strategies of sustainable development was universally recognized. It is acknowledged that sustainable preservation, maintenance, and use of cultural heritage, especially immovable, positively influence the social, economic, cultural and even environmental dimensions of sustainable development. Sustainable development opportunities provided by immovable cultural heritage are essential for small rural settlements which are not distinguished by important natural resources or favorable location. In this instance social and cultural viability is as much essential for preservation of immovable cultural heritage of these settlements, as immovable cultural heritage is essential for sustention of their social and economic viability. Nekilnojamojo kultūros paveldo įtaka darniam kaimo gyvenamųjų vietovių vystymuisi Santrauka Didžiąją Lietuvos, kaip ir visos Europos, teritorijos dalį sudaro kaimo vietovės, o didžiąją dalį gyvenamųjų vietovių – kaimo gyvenamosios vietovės, taigi jų socialinis, eko nominis ir kultūrinis gyvybingumas bei eko loginis tvarumas atlieka lemiamą vaidmenį siekiant šalies darnaus vystymosi tikslų. Pastaraisiais metais darnų vystymąsi skatinantys projektai jau įgyvendinami ne tik didžiuosiuose Lietuvos miestuose, bet ir mažesnėse savivaldybėse, tačiau daugelio kaimo gyvenamųjų vietovių šis procesas kol kas nepaliečia. Bendro šalies gyventojų skaičiaus mažėjimo tendencija, emigracija, jaunų ir kvalifikuo tų žmonių migracija į didžiuosius šalies miestus, skurdas ir nedarbo grėsmė kelia sunykimo grėsmę patiems jautriausiems ir kultūriniu požiūriu vertingiausiems šalies kaimo gyvenamųjų vietovių sistemos elementams, tokiems kaip vienkieminės sodybos, buvusių dvarų ir palivarkų sodybos ar etnografinės kaimų gyvenvietės. Siekiant sustabdyti šiuos neigiamus socialinius, eko nominius bei kultūriniu procesus, būtina ieškoti būdų, kaip užtikrinti kaimo gyvenamųjų vietovių socialinį bei eko nominį gyvybingumą. Pastaraisiais metais pasaulyje vis aiškiau suvokiamas kultūros paveldo vaidmuo darnaus vystymosi kontekste. Visuotinai pripažįstama, jog kultūros paveldo, ypač nekilnojamojo, apsauga, priežiūra bei naudojimas turi teigiamos įtakos darniam vystymuisi socialinėje, eko nominėje, kultūrinėje ir kt. dimensijose. Nekilnojamojo kultūros paveldo teikiamos darnaus vystymosi galimybės itin reikšmingos nedidelėms, išskirtinių gamtinių išteklių neturinčioms bei patogia geografine padėtimi nepasižyminčioms kaimo gyvenamosioms vietovėms. Jų socialinis ir eko nominis gyvybingumas kultūros paveldui išsaugoti yra toks pats svarbus, kaip ir kultūros paveldas socialinio ir eko nominio šių gyvenamųjų vietovių gyvybingumo palaikymu.

The role of financial development (FD) in China’s environment has attracted extensive attention from scholars, but few studies involved the effect of FD on urban electricity consumption (EC). This paper constructs two spatial panel models to explore the interaction between FD and EC on the basis panel data of 278 cities in China from 2005 to 2016. The results show that electricity consumption of urban residents and industrial sector in China has obvious spatial correlation and unbalanced spatial distribution. Secondly, FD can promote urban industrial electricity consumption (IEC) and urban residential electricity consumption (REC), and it has a greater impact on REC than IEC. Thirdly, spatial heterogeneity is established, and the imbalance of REC and IEC among different regions and urban scales deserves more attention. FD is conducive to enhance REC and IEC in the eastern and western regions. Meanwhile, FD plays an important role in the increase of REC and IEC in small cities, large cities, and megacities of China. Considering the above results, this paper puts forward targeted policy recommendations.

<p>The paper focuses on the diversification of single-industry towns’ economy and identifies the role of networking in this process. The author presents preliminary results of the Russian Science Foundation project "Sustainable development of the territorial<br />economy through networking of small cities and district centers". The goal of the project is to identify opportunities to overcome the growing gap in the level and quality of life in small Russian towns vs. large cities and megacities, and to propose measures for combining<br />resources and competencies of small cities in the framework of network relationships. The cases of Tula, Vladimir and Perm regions were in the focus of research. To achieve the research goal, a set of methods was applicable, including system analysis, formal logical<br />method, dialectical method, as well as quantitative and qualitative marketing research. This allows us to draw conclusions about the presence of structural problems and contemporary trends, and to offer recommendations taking into account the specialization of small singleindustry towns. Serious problems faced by the municipalities of single-industry towns, and the obstacles to efficient inter-municipal cooperation have been identified. At the same time, international evidence shows that the formation of a favorable institutional<br />environment for mutually beneficial combination of resources and competences of singleindustry towns with different specialization facilitates the implementation of joint projects and makes it possible to accelerate the processes of economic diversification by using the<br />benefits of a network coordination mechanism</p>

There was elucidated the original approach to the evaluation of phytopopulation size structure. For its characteristics it was offered to use the special index - index diversity of size structure (ІDSS). There are presented methods and algorithm of its determination. There was demonstrated that index diversity of size structure can be used at populational studies of species that belong to the different living forms. Especially phanerophytes (Pinus sylvestris) and hamephytes (Ledum palustre). As to Pinus sylvestris and Ledum palustre with help of index diversity of size structure was objectively proved that its cohorts and ontogenetic groups that growth in composition of forest phytocenoses typical for Ukrainian Polissya are not characterized with high level diversity of size structure. The value of index diversity of size structure is mainly less than 20 %. In phytopopulation the specific and phytocenotic peculiarity is demonstrated by diversity of size structure and also by representation of plants of certain size classes.

Services that link buyer and seller across nations and continents have long been a part of city and port development, but have not attracted much research interest, perhaps because they remain (like their statistical record) ‘invisible’. Technical and structural change in the organisation of shipping, reflected largely in containerisation, have changed the context for these services and they have responded in a variety of ways. Data in this paper trace the location of a selection of these services in the USA and Australia, indicating a separation between services and negotiations on aspects of trade services, and new patterns of physical activity in trade. It is suggested that this separation may be facilitated by the standardisation that has come with containerisation, the importance of intercorporate linkages, the role of official markets, and the application of modern communication technology. These aspects account for the clustering of services in large cities and their separation from day-to-day trade business, and could provide insights for producer-service location in general. The paper indicates the need for survey work to test these ideas.

This chapter discusses the structural difference in family size, structure, location, and preferences, as well as the features of the formal and informal financial markets that determine the access to credit of various types of firms. It also reviews the role of the exchange rate, interest, rate and inflation in determining money demand. It then discusses behavioural equations for aggregate consumption, investment, and money demand that fit the reality of developing countries, and compares them with those discussed in Chapter 3 for the advanced economies. It shows that their inclusion in the IS-LM and AS-AD models often modifies the impact of policy changes and endogenous shocks in relation to those obtained in the advanced economies.

Skill upgrading, the increase in the percentage of skilled workers in the employment population, boosts the economic growth of developing countries and sustains their industrial competitiveness. The international economics literature discusses the effects of international trade on skill upgrading, ignoring the potential role of agglomeration externalities. This paper takes China as a case study, which has been encountering a serious challenge about how to strengthen its industrial competitiveness in the world through skill upgrading as its population dividend decreases. The panel data of 2005, 2010 and 2015 from prefecture-level cities in China were used for regression analysis to explore the benefits from agglomeration externalities, including specialization and diversification effects, on skill upgrading. The results show that both the specialization effect and diversification effect do promote skill upgrading. Furthermore, there are significant differences in the influence of local agglomeration externalities across different regions, and the positive effect brought about by specialization externalities is usually dominant in undeveloped, inland or small cities, compared with the diversification in developed or coastal cities. Besides, manufacturing agglomerations exhibit positive externalities to skill upgrading mainly through specialization, while the service agglomerations mainly promote skill upgrading by means of diversification.

AbstractThe EC-Biotech dispute exposed the WTO dispute settlement system to a more challenging test than any previous dispute. Not only did the Panel have to take a stand on the limits of science, or technocratic regulatory controls, to protect against objective risk, but in this regard faced more complex issues than ever addressed before by an adjudicating body. The dispute also concerned an extremely charged political issue, partly because of inherent ethical sensitivities with regard to foodstuffs, partly due to public skepticism about the role of science, and partly due to a common public perception of the complaint as being driven by the interests of an untrustworthy industry. Because of these and other challenges, the Panel faced an almost impossible task. This paper discusses how the Panel addressed some of these issues. The recently (after our report was drafted) decided appeal in EC–Hormones Suspension is likely to reduce the significance for WTO jurisprudence of some of the Panel's findings in EC–Biotech, given the apparently different approach of the AB to fundamental interpretative issues under SPS concerning the meaning of risk assessment and precaution.

This chapter begins with an overview of the major approaches and potential limitations of defining the informal sector, followed by an analysis of its size, structure, and institutional context. It then considers the taxation of informal firms and notes the pervasiveness of tax evasion in the informal sector, along with state failures and informal employment, earnings differentials between formal and informal actors, and the role of rural–urban migration in the rise of informal labor force in developing countries. The chapter explores why informality is so pervasive in Africa; why informal firms are less productive than their formal counterparts; whether it is best for development to proceed in order to get informal firms to register and pay formal taxes; and how to help informal firms and those employed in the informal sector. Finally, it discusses a good approach to development that takes into account the existence of the informal sector.
