相关多样化、非相关多样化与区域创新产出——以长三角地区为例

创新是当今区域经济增长的关键驱动力之一,区域多样化与区域发展之关联是经济地理学研究的重要议题。目前国内的创新来源逐渐从外部知识引进为主向依靠区域自身创新能力为主转变,即重视本地知识结构对创新产出的重要影响。然而,现有研究主要关注多样化对区域经济发展的影响,较少分析多样化对区域创新产出的影响,也很少涉及多样化对邻近地区创新产出的空间效应。为此,本文构建了分析相关多样化和非相关多样化对区域创新产出影响的理论框架,并基于2011—2016年长三角地区26个地级市IPC分类专利的面板数据,运用空间杜宾模型,分析了本地知识结构的多样化对区域创新产出的影响。研究发现:(1)长三角城市群内部相关多样化与非相关多样化格局相似,省际间呈现沿海高内部低、省内呈现中心城市高周围城市低的空间格局。(2)知识相关多样化能够促进地方创新产出,而非相关多样化与地方创新产出之间呈现倒U型关系,即区域过度的非相关多样化对其创新产出有负向影响。(3)本地创新受相邻地区相关多样化的负向影响。本文对长三角区域创新机理的研究对于丰富我国创新地理学的理论与应用具有重要意义。     

(Un)related variety,urban milieu and tourism-company differentiation

High tourism growth in single-asset tourism cities is often associated with a standardization of supply of products and services by tourism entrepreneurs. However, and in contrast to this common-sense view, tourism growth in specific urban tourism milieus in the ‘sun-sea-sand’ tourism city of Antalya has stimulated tourism entrepreneurs to differentiate their products. Contrary to most economic-geography literature on spatial clusters, evolutionary economic geographers argue that inter-industry relations of (un)related variety are crucial in inter-firm differentiation. The aim of the paper is to define the factors that influence tourism-firm differentiation in the single-asset tourism city of Antalya. The empirical research is theoretically informed by evolutionary economic-geography literature, and pays much attention to the role different urban sub-milieus play in tourism-firm differentiation. It is the first research on the relation between (un)related variety and tourism-firm differentiation in tourism studies. The empirical research is based on primary data collected by a firm-level survey (hotels, restaurants, jewellery- and retail-trade firms) in the city of Antalya. The factors that influence tourism-firm differentiation are explored by using quantitative methods of analysis (an econometric logit-regression model and a correspondence analysis). The main result of the empirical research is that investments in firms in related sectors, in our case jewellery companies and hotels, are positively and significantly related to tourism-firm differentiation. In addition, the location tourism firms in areas visited by a mix of consumers (tourists and locals) also is positively and significantly related to inter-firm differentiation whereas urban milieus visited by locals only have a negative effect.     

Bridging the divide between studies on disaster risk reduction education and child-centred disaster risk reduction: a critical review

There has been a recent increase in the body of knowledge related to children and disasters. These studies converge into three main fields of research: the impact of disasters on children and their psychological recovery, the integration of disaster risk reduction (DRR) into the education sectors and children’s participation in DRR. This article provides a literature review of the two latter fields of research where the focus is on reducing disaster losses and building resilience prior to a disaster. Overall, 48 studies are critically reviewed and compared in relation to the strengths and weaknesses of their aims, methods, locations of research, impact, and outcomes. The review identified a number of differences between the two fields and significant opportunities for linking the two approaches, sharing lessons and knowledge. Based on the review, recommendations for further research are outlined.

Measuring relatedness in a multisectoral cluster: an input–output approach

Studies in evolutionary economic geography have found that knowledge spillovers, crucial for the development and maintenance of clusters, tend to flow between sectors that are related via similar inputs and/or outputs. Thus, there is a growing body of literature stating that industrial variety within clusters is beneficial for economic growth, whereby local industrial diversity sparks creativity, new ideas and innovations. Within this context, the Irish Maritime and Energy Resource Cluster (IMERC) is a diverse, multisectoral cluster. Using an Input–Output table this paper examines the intra-cluster linkages, as well as the relatedness in terms of inputs and outputs across the four IMERC pillars: Marine Energy; Shipping, Logistics and Transport; Maritime Safety and Security; and Yachting Products and Services. This analysis found that although IMERC has weak intra-cluster linkages, the four pillars share a high number of related inputs and outputs. Based on this analysis, IMERC has the potential to develop into a strong maritime cluster.     

British policy and European reconstruction after the first World War

The paper relates the concept of a European political identity to the development of the European Community's foreign policy. After a brief review of the idea of political identity as it developed in Europe over the last five centuries, the paper relates this concept to that of liberal democracy. It then turns to the European Community and the growth of its foreign policy. It addresses two questions: Could the concept of political loyalty to a territorially defined identity be replaced by that of institutional loyalty to not one, but a variety of overlapping institutions? Secondly, can the development of the European Community's foreign policy contribute to the development of a European sense of identity? Two short case studies, one on Yugoslavia, and one on economic aid to Eastern Europe, illustrate recent European Community foreign policy. The paper concludes with some speculations as to the future European political system and its applicability to other parts of the world.     

A theoretical framework for evolutionary economic geography: industrial dynamics and urban growth as a branching process

We propose a framework that specifies the process of economicdevelopment as an evolutionary branching process of productinnovations. Each product innovation provides a growth opportunityfor an existing firm or a new firm, and for an existing cityor a new city. One can then obtain both firm size and city sizedistributions as two aggregates resulting from a single evolutionaryprocess. Gains from variety at the firm level (economies ofscope) and the urban level (Jacobs externalities) provide thecentral feedback mechanism in economic development generatingstrong path dependencies in the spatial concentration of industriesand the specialization of cities. Gains from size are also expected,yet these are ultimately bounded by increasing wages. The contributionof our framework lies in providing a micro-foundation of economicgeography in terms of the interplay between industrial dynamicsand urban growth. The framework is sufficiently general to investigatesystematically a number of stylized facts in economic geography,while at the same time it is sufficiently flexible to be extendedsuch as to become applicable in more specific micro-contexts.A number of extensions related to the concepts of knowledgespillover and lock-in, are also discussed.     

Regional skill relatedness: towards a new measure of regional related diversification

ABSTRACT

This paper proposes a novel index of regional skill-relatedness and calculates this measure for all Norwegian labour-market regions. Studies of regional related diversification rely on measures of related variety, which build on the industry classification hierarchy. However, the growing literature identifying similarities in knowledge and competences across industries demonstrates that these classifications fail to identify a great deal of actual skill relatedness, and that measures based on empirical measures of industry relatedness are required. The skill relatedness measure builds on labour mobility flows across industries to develop a relatedness matrix for Norwegian industries. It further uses social network analysis to identify the number of other regional industries to which each industry in a particular region is related. Comparing this measure to the related variety index, the analysis shows that the two measures are highly correlated, but that the regional skill relatedness index is able to identify more of the relatedness across industries. In particular, the related variety index tends to underestimate the level of relatedness in many of Norway’s most technologically sophisticated manufacturing regions, whereas these rank highly in the regional skill relatedness index. Consequently, the regional skill relatedness index represents a promising new tool for identifying relatedness in regional systems.     

Age estimation of children from prehistoric Southeast Asia: are the dental formation methods used appropriate?

Inter-population differences in skeletal and dental growth and maturation are acknowledged frequently in the biological anthropological literature. These growth differences have implications for the reliability of standards for the estimation of age at death of archaeological subadults. The number of archaeological projects that are recovering human burials from non-European contexts, including Southeast Asia, and the increasing interest in subadult bioarchaeological studies provides the impetus for investigating this issue of ageing subadult individuals from these populations. This paper aims to address some of the problems of the representativeness of ageing standards for non-European children in bioarchaeology. This is achieved through a literature review of the issue of growth variability and age estimation, and a basic comparison of the commonly applied age estimation method based on North American children with a dental formation study of modern Thai children. Although these studies do not employ similar methods the Thai study is the only comparable data available and therefore serves as a starting point to address these issues. The results raise an important question for bioarchaeologists of the appropriateness of available ageing methods. In addition this paper emphasises the need for the use of appropriate methodologies in the collection and presentation of dental formation data.     

Out of the crisis: an empirical investigation of place-specific determinants of economic resilience

This article attempts to isolate the structural characteristics that affect the resilience of a regional economy. It focuses on the role played by related/unrelated variety and differentiated knowledge bases as drivers for regional resilience and originally explores their interdependences. Italy is the empirical setting, and Italian local labour systems the unit of analysis. Regional resilience is measured as growth of the employment rate after the Great Recession that began in 2008. Results confirm the importance of related variety and of differentiated knowledge bases as drivers for regional resilience. We found support of the creative capacity of culture argument, providing evidence that a moderate concentration in symbolic knowledge-based economic activities contributes to resilience. Synthetic and analytical knowledge-based activities provide positive and no support to regional resilience, respectively. Finally, the relatedness of the symbolic knowledge-based activities increases regional economic resilience. Some policy implications are then derived from these findings.     

How much does urban location matter for growth?

This paper analyses the effect of location characteristics on urban growth using regression cubic splines. Our empirical analysis shows that in Spain, differences in accessibility to major urban centres and geographic isolation help explain differences in population growth rates across municipalities between 2001 and 2014. Moreover, even though physical proximity to large cities is usually assumed to be closely related to the attractiveness of a municipality, we found that urban population growth is even more related to the joint effect of distance to major centres and agglomeration. In this respect, there seems to be a threshold from which agglomeration diseconomies come into play such that a greater proximity to major cities and/or being localized within a more densely populated area goes against local growth.     

OBSIDIAN IN THE MEDITERRANEAN AND THE NEAR EAST: A PROVENANCING SUCCESS STORY

Obsidian provenancing studies comprise one of the most productive and successful research programmes of archaeological science. Obsidian characterization has been successful because workable obsidian is homogeneous on a small scale, analysable by a large number of methods, and is restricted to a small number of mainly readily distinguishable geological sources. Analytical, dating, source, and trade studies within the western Mediterranean, central and eastern Europe, the Aegean, and Anatolia and the Near East during the last 30 years or so are reviewed. Research has shown that distributions are mainly separate in the four regions examined, and that obsidian was traded up to 900km in the prehistoric period. Publications on obsidian in the areas under review reached a peak of frequency in the later 1970s and 1980s, but have now decreased in number. This may reflect changing fashions in archaeometric studies, and a current lack of routine application of the provenancing methods developed.     

Agglomeration,foreign firms and firm exit in regions under transition: the increasing importance of related variety in Hungary

ABSTRACT

Related variety of economic activities is widely recognized to induce regional development; however, it is not clear how this mechanism takes place in regions that go through major structural and institutional transformation. Furthermore, foreign direct investment (FDI) is typically a major source of structural change in these areas; and we still need a better understanding on how foreign-owned (foreign) firms affect the dynamics of domestic-owned (domestic) companies. For these reasons we analyse firm-level exit in Hungarian city regions between 1996 and 2011, over the late post-socialist transition in manufacturing industries, focusing on the difference between foreign and domestic firms. Introducing ownership into the related variety calculation, we estimate the probability of firm exit with the region-level related variety calculated separately for foreign and domestic firms. Our results suggest that related variety of foreign firms decreases the probability of domestic firm exit earlier during the economic transition compared to the related variety of domestic firms. This finding supports the idea that FDI plays a formative role in regions under transition, and shows that domestic firms benefit from being in agglomerations where foreign firms are technologically related to each other.     

Muslim immigrants' sense of identity and belonging in the Western world: A comprehensive review

In recent years, much has been written about the growth of anti‐immigrant sentiment in Western countries. Propagated by the fastest growing party family, far right‐wing parties, there is growing support in Western populations in favour of scapegoating Muslim immigrants for economic, cultural and security problems. However, less has been written on how Muslim immigrants feel about their host country. What is their sense of belonging and identification with their country of residence? In this review article, we summarise the results of 29 studies that explicitly focus on questions of integration, national identity and sense of belonging of Muslim immigrants. The studies we review document a range of outcomes, varying from a low sense of belonging and attachment to the country of residence to extremely high integration levels and loyalty. It seems that most variation depends on the country of residence at the macro‐level and on their education at the individual level.

Simulating changes in tourism demand: a case study of two German regions

Travel behaviour is shaped by the complex interaction of a variety of societal, economic, ecological and political drivers that undergo rapid changes. This poses continually new challenges on destinations which need to adapt to altering conditions. Significant changes of influencing factors might lead to shifts in tourism flows in temporal and/or spatial dimensions. This study investigates how German tourists’ destination choices develop under changing framework conditions. It furthermore rates the impact of influencing factors such as socio-demographic and socio-economic aspects on changes in tourism demand using an agent-based model. The interactions among 15 million tourists and 109 European destinations are simulated under three different scenarios. Destinations included in the model develop in different ways in regard to tourist arrivals until 2030. The results indicate that the number of tourist arrivals will develop divergently in the investigated regions until 2030 and that some market segments will undergo changes in seasonality: the model shows a growth in arrivals for many city destinations, cultural as well as sports and active tourism destinations. It indicates a trend towards equalisation in the segments sun and sea tourism, city and cultural tourism with a shift from summer months to spring and autumn towards 2030. They furthermore imply that demographic change dominates altering tourism demand in the source market and that related changes in travel preferences are the most urgent challenge for destinations.     

Electronic Information Management for Administrative Government

Abstract

This review defines applied informatics and indicates its use in tbe public sector. It distinguishes different sector of public endeavour and different types of information systems with regard to the informational infrastructure in a country. For this purpose recent literature from a number of developed countries is surveyed and abstracted from a variety of different disciplines. The relations between technological and methodological developments on the one hand, and organizational and administrative developments on the other are especially discussed. Some general trends are tentatively discerned. The main conclusion is that the potential use of applied informatics as a tool of administration is insufficiently realized, both in politics and in academic research.     

Policies of related variety in practice: the case Innovation Session Method

The article describes the foundations of related-variety policies in practice, delineating the roles that related variety and fruitful distances may play in innovation policy. The main focus is on methods of managing related variety. Three types of regional collaboration and renewal processes are identified. By presenting empirical research on the Innovation Session Method developed in the Lahti region of Finland, the article provides insights into the practical implementation of innovation policy based on related variety. This study finds that Innovation Sessions appear to function quite well in the related-variety context, serving as a practical implementation of innovation policy that is in transition. The role of an optimal combination of distances is highlighted. This study contributes to the development of effective methods for innovation policy.     

Cournot Retail Chains

In this paper a model of spatial Cournot competition among retail firms is devised and used to assess the effect of a variety of structural factors on retail prices and profits. The model illustrates the spatial chain of interaction that firms must anticipate to reach equilibrium when organized in chains or as independents. It shows the sensitivity of price to the location of stores, the number of stores per location, and transportation cost.     

How Legislative (In)Activity,Ideological Divergence,and Divided Government Impact Executive Unilateralism: A Test of Three Theories

During the past two decades scholars from a variety of different fields (law, history, journalism, political science) have written extensively about the development and implementation of the Unilateral Presidency. Because several explanations for unilateral action have been posited, we provide a thorough test of three theories of executive unilateral action. Applying a newly-developed methodology to the most comprehensive dataset of unilateral presidential directives to date, results of the Bayesian Poisson Vector Autoregressive model suggest that although executive orders, memoranda, and proclamations are all strategic tools that presidents utilize to unilaterally alter policy, fundamental differences exist between them, as well as the inter-dependence among them. More important, our results show that whereas the percentage of bills passed is related to presidential proclamations, legislative activity actually depends on the number of executive orders issued. However, CQ success scores are related to both executive orders and presidential proclamations. We also find that presidential ideology and congressional ideology are related to executive action, whereas the impact of divided government is at best only weakly related.
