The Growing Economic Specialization of Cities: Disentangling Industrial and Functional Dimensions in the Canadian Urban System, 1971–2006

Decreasing spatial transaction and trade costs have given rise to growing economic specialization of cities. While most studies focus on industries as the primary manifestation of urban specialization, a growing body of literature examines occupational functions, i.e., activities and tasks performed within a given industry or firm. This paper explores how the two dimensions (industries and functions) interact across the urban system and their relative importance over time. Is there a trend toward increasing functional specialization in the Canadian urban system? How much of this phenomenon is attributable to spatial shifts in regional industrial structures as opposed to spatial divisions within industries? The paper uses a unique data set drawn from Statistics Canada Census microdata files between 1971 and 2006. Based on the employed population, the data are spatially organized and cross‐tabulated over industries and occupational groups. A decomposition methodology is used to compare the relative weights of industry and regional (functional) effects in accounting for the changing spatial division of functions across Canadian urban areas. Clear patterns of increasing functional specialization are found within the Canadian urban system. Regional effects are generally greater than industry effects, suggesting that spatial divisions of functions (spatial shifts within industries) are progressing more rapidly than regional shifts in industrial structure.     

Location Decision Making of “Creative” Industries: The Media and Computer Game Sectors in Dublin,Ireland

There has been significant research undertaken examining the “creative class” thesis within the context of the locational preferences of creative workers. However, relatively little attention has been given to the locational preferences of creative companies within the same context. This paper reports on research conducted to qualitatively analyse the location decision making of companies in two creative sectors: media and computer games. We address the role of the so‐called “hard” and “soft” factors in company location decision making within the context of the creative class thesis, which suggests that company location is primarily determined by “soft” factors rather than “hard” factors. The study focuses upon “core” creative industries in the media and computer game sectors and utilises interview data with company managers and key elite actors in the sector to investigate the foregoing questions. The results show that “hard” factors are of primary importance for the location decision making in the sectors analysed, but that “soft” factors play quite an important role when “hard” factors are satisfactory in more than one competing city‐region.     

Unveiling various spatial patterns of determinants of hukou transfer intentions in China: A multi-scale geographically weighted regression approach

As the floating population has become a vital issue influencing China's economic and social development and aroused broad concern, many scholars have paid attention to the factors that influence settlement intentions of the floating population, while their spatial differences are usually neglected in extant studies. To rectify this situation, this study employs a multi-scale geographically weighted regression model to investigate the spatial pattern of determinants on hukou transfer intentions of the floating population, based on the data of the China Migrants Dynamic Survey in 2016. The results demonstrate that the effects of various determinants present different spatial patterns: part of significance pattern (the average residence time in destination cities, the ratio of rural hukou holders, the number of flows, the ratio of family income to family expenditure, the geographical location), the “East-West” pattern (the ratio of self-employed migrants, the average wage of employed workers), the “Southwest-Northeast” pattern (the ratio of migrants in the secondary industry, the ratio of sharing town employees' social insurance, the ratio of floating population accompanied by children in destination cities, and the population density of municipal districts). Cities of different conditions should formulate different policies that are sensitive to their contexts.     

Regional Growth Dynamics in the Service Sector: The Determinants of Employment Change in UK Regions, 1971–2005

There is a need to better understand the dynamics relating to the evolving economic structure of regions, in particular factors concerning deindustrialisation and the growth of services. In order to unpick the dynamics relating to contemporary regional evolution, this paper examines regional employment in the UK's services sectors from 1971 to 2005. The analysis utilises the statistical technique of multi‐factor partitioning to examine the evolutionary dynamics of employment change in the UK service sector. Overall, differing growth trajectories in services employment across regions appear to be the result of the different underlying industrial structures observed within the regions themselves. The findings indicate that the industrial structure of a region has a significant influence on employment change in services, with related variety being of greater consequence than specialisation. This suggests that diversity, or urbanisation, effects have a greater influence than specialisation effects on “lighter” industries than “heavier” industries. Spatio‐temporal variations within the development of services are evident in the analysis, and there is evidence of convergence across the regions for all sub‐sectors examined. It concludes that in an increasingly services‐dominated economy, diversity and related variety have some weight in explaining regional development paths.     

Spatial Divisions of Corporate Services Occupations in the United States, 1983–88

This article examines corporate services from a regional perspective, using the concept of “spatial divisions of labor.” We examine non-routine, control-related activity as well as routine activity, bridging the literatures on white- and pink-collar work. Using the Geographic Profile on Employment and Unemployment, published by the U.S. Department of Labor, we examine occupational data across the nine census divisions continuously from 1983 through 1988. This data source is unique because it reports on occupational data annually, in relatively disaggregate form, and does so by geographic regions. Location quotients for the occupational data serve to identify a “core” with respect to concentrations of control-related activity. This core comprises the New England, Middle Atlantic, and Pacific divisions. In contrast, routine activity generally is more dispersed, although some regional separation is evident for specific occupations, showing regional concentration in subordinate or “peripheral” regions. The results of the study identify regional patterns, which are heuristically valuable in raising questions regarding the complex processes responsible for spatial divisions of labor. In particular, the findings suggest a geography of modes of production, a subject that requires substantially more attention.     

Who leads regional industrial dynamics? “New industry creators” in Chinese regions

Recent evolutionary economic geography studies have argued that regional diversification emerges as a path‐dependent process, as regions often branch into industries that are related to its industrial structure. However, it is less clear who are creating new industries and under what regional conditions. This research seeks to fill this gap and identify “new industry creators” in regional industrial diversification. We differentiate two types of new industry formation—path‐breaking and path‐dependent—and examine whether some new industry creators are more path‐breaking than others, by incorporating two factors that have been largely overlooked in recent literature on technological relatedness—firm heterogeneity and regional institutions. Based on a firm‐level data set of China’s manufacturing industries, this paper shows that path‐breaking and path‐dependence coexist. Empirical results confirm that firm heterogeneity and regional institutions not only affect the firms’ capabilities in creating new industries, but also encourage/discourage firms to be adventurous and path‐breaking. This research implies that lagging regions can catch up with developed regions by coordinating regional resources and adjusting local institutional arrangements to attract more path‐breaking firms.     

Innovation in suburban development zones: Evidence from Nanjing,China

While suburban areas have been typically related with urban sprawl, low density, cheap land price and low‐end manufacturing industries, relatively little attention has been paid to the spatial organization of innovation in suburban areas. In some Chinese cities, development zones (kai fa qu) in their suburban areas which are generally regarded as major spaces for traditional manufacturing industries have been transforming into spaces for innovation. This paper provides a case study of Nanjing, the capital of Jiangsu province in Eastern China by investigating and explaining the learning and innovation processes in suburban development zones. Drawing upon a unique database on 733 state‐certified high‐tech firms in Nanjing from 2008 to 2012 which contains detailed information on their addresses and number of patents, we observe strong spatial disparity in the distribution of innovation. Suburban districts of Nanjing where its three national‐level development zones and many provincial‐level development zones are located have become major spaces for innovation of the city. The planning of industrial clusters in development zones, the place‐based investment in the suburbs, and the suburbanization of universities are three major mechanisms behind the learning and innovation processes in Nanjing’s suburban development zones.     

Technology Search and Firm Bounds in Biotechnology: New Firms as Agents of Change

Schumpeterian perspectives on industrial change suggest a relationship between new firms and the regionally specific technological bases for innovation. However, the links between such firms and the knowledge bases for innovation are more implicit than explicit. The innovation process in new firms reflects both the capabilities found within the firm as well as information sourcing from without. This paper seeks to articulate the nature of change in relationships between firms in science-based industries and the technological infrastructure accessed to support innovation, as such industries mature out of the birth phase. Innovation is treated as decision making, identifying the firm as innovator and agent of change. Survey research suggests that a shift in the sourcing of information, and an associated shift in the character of information accessed, occurred with maturation in the study industry, comprised of biotechnology firms in the U.S. “Early” and “later” forming firms show somewhat different technology sourcing patterns. Interviews were conducted to help interpret these findings. Implications for industry development are suggested.     

Beyond “Global Production Networks”: Australian Fashion Week's Trans‐Sectoral Synergies

ABSTRACT When studies of industrial organisation are informed by commodity chain, actor network, or global production network theories and focus on tracing commodity flows, social networks, or a combination of the two, they can easily overlook the less routine trans‐sectoral associations that are crucial to the creation and realisation of value. This paper shifts attention to identifying the sites at which diverse specialisations meet to concentrate and amplify mutually reinforcing circuits of value. These valorisation processes are demonstrated in the case of Australian Fashion Week, an event in which multiple interests converge to synchronize different expressions of fashion ideas, actively construct fashion markets and enhance the value of a diverse range of fashionable commodities. Conceptualising these interconnected industries as components of a trans‐sectoral fashion complex has implications for understanding regional development, world cities, production location, and the manner in which production systems “touch down” in different places.     

Nitrogen fertilization of warm‐season turfgrasses irrigated with saline water from varying irrigation systems. 1. Quality,spring green‐up and fall colour retention

A 3‐year study was conducted at New Mexico State University in Las Cruces, NM, to investigate the effects of different fertilization treatments on turf performance when water conservation strategies are applied. These strategies include the use of non‐potable saline irrigation water and the use of efficient subsurface irrigation systems. Two low water use warm‐season grasses, “Princess 77” bermudagrass (Cynodon dactylon L.) and “Sea Spray” seashore paspalum (Paspalum vaginatum O. Swartz), were irrigated with either potable [Electrical Conductivity (EC) = 0.6 dS/m] or saline (EC = 3.1 dS/m) water from either an overhead or a subsurface drip irrigation (SDI) system. Four different fertilizers, liquid slow release, granular slow release, granular urea and liquid urea, were applied at two rates: 10 and 20 g N m^?2 year^?1 for “Sea Spray” and 20 and 30 g N m^?2 year^?1 for “Princess 77.” Spring green‐up, summer quality and fall colour retention were determined using digital image analysis, visual quality ratings and normalized difference vegetation index. Generally, subsurface drip‐irrigated grasses were slower to green‐up than overhead irrigated ones. “Sea Spray” irrigated from the SDI system took 18, 28 and 15 days longer to reach 80% green cover in 2010, 2011 and 2012, respectively, than their sprinkler‐irrigated counterparts. The combination of “Princess 77” and overhead irrigation reached 80% green cover 35 (in 2010), 34 (in 2011) and 12 (in 2012) days faster than SDI‐irrigated “Princess 77.” Fertilization rate and type had no effect on summer turfgrass quality of “Princess 77” irrigated from a sprinkler system throughout the research period reaching ratings of greater than 7 during all 3 years. Similar results were observed for “Princess 77” irrigated from a SDI system during 2010 and 2011. Summer quality of sprinkler‐irrigated “Sea Spray” was negatively affected by liquid fertilization. During two of three summers, visual quality of plots fertilized with either liquid slow release or liquid urea was lower than “Sea Spray” fertilized with granular fertilizer. Further research is needed to investigate the effect of fertilization on bermudagrass and seashore paspalum over a wider nitrogen range including both granular and foliar products.     

Alleles on the two dwarfing loci on 4B and 4D are main drivers of FHB‐related traits in the Canadian winter wheat population “Vienna” × “25R47”

Fusarium head blight (FHB), leaf rust and stem rust are among the most destructive wheat diseases. High‐yielding, native disease resistance sources are available in North America. The objective of this study was to map loci associated with FHB traits, leaf rust, stem rust and plant height in a “Vienna”/”25R47” population. DArT markers were used to generate a genetic map, and quantitative trait loci (QTL) analysis was performed by evaluating 113 doubled haploid lines across three environments in Ontario, Canada. FHB resistance QTL were identified on chromosomes 4D, 4B, 2D and 7A, while a QTL for leaf and stem rust resistance was identified on chromosome 1B. The dwarfing alleles of both Rht‐B1 and Rht‐D1 were associated with increased FHB index and DON content.     

Towards the Spatial Patterns of Sectoral Adjustments to Trade Liberalisation: The Case of NAFTA in Mexico

ABSTRACT A recent string of “new economic geography” (NEG) models has set focus on the impacts of trade liberalisation on the intra‐national distribution of economic activity. What the existing contributions have in common is a basic two‐sector assumption (agriculture/manufacturing) and a resulting focus on the question of whether liberalisation leads to a greater concentration of aggregate manufacturing activity. Reconsidering these models from a multi‐sectoral perspective, the aim is to allow for sectoral differences in the spatial adjustments to liberalisation. This introduces a conceptual nexus between comparative advantage (CA)‐type sectoral recomposition effects of trade and NEG‐type spatial adjustments. In the analysis of Mexican manufacturing location 1993–2003, incipient empirical evidence is found in favour of the hypothesis that sectors characterised by a revealed comparative advantage and/or cross‐border intermediate supplies grow faster in regions with good foreign market access, whereas import competing ones gain in relative terms in regions with higher “natural protection” from poor market access. The relevancy of the proposed NEG/CA framework concerns both efficiency and equity objectives of trade adjustment policies, and opens a new perspective on the long‐run effects of trade on spatial inequality.     

The elusive quest for balanced regional growth from Barlow to Brexit: Lessons from partitioning regional employment growth in Great Britain

The British Government’s economic strategy for post‐Brexit Britain of achieving balanced regional growth by “driving growth across the whole country” echoes the objectives set by the Barlow Report of 1940. The regional policies that followed the Barlow Report were heavily influenced by papers written for the Commission by G D A (later Sir Donald) MacDougall. The first of these papers was included as an appendix to the report itself and introduced the shift‐share methodology to the analysis of regional employment growth, and subsequently shown to be flawed. The second paper considered the urban hierarchy and growth but was never fully developed. Consequently post‐war regional policy focussed on the contribution of industrial structure to employment growth without fully taking into account the urban hierarchy or regional locations of that employment. This article replaces the flawed shift‐share methodology with multifactor partitioning (MFP) and applies it to regional employment growth for the period 1971‐2012, a span of special interest because it largely coincides with British membership of the European Union (EU). The deficiencies in the second paper are addressed by introducing allometry to measure the employment growth of each region relative to that of Great Britain and then regression analysis to relate the allometries to distance from London. The results of the two sets of analyses highlight the need for a multiple‐factor, comprehensive, and integrated approach to regional policy and provide a benchmark against which to gauge the success of Britain's post‐Brexit policy of driving future growth across the whole country.     

A Linkage Approach to Industrial Location

Access to markets and raw materials is nearly always mentioned in industrial location studies as an important locational factor. This article demonstrates a methodological approach based on inter-industry linkages and using secondary data to identify target industries for economic development initiatives. In this application we characterize Alabama's industrial base, identify industries with strong forward and backward linkages to base Alabama industries, and highlight a subset of especially good prospects.     

A Note on Localization and Specialization

ABSTRACT Analysts and policy makers frequently measure industrial localization and regional specialization. However, they rarely examine the nation's full array of industries or regions. So local indices, appropriate for specific industries or selected regions, are typically estimated. But in some instances global indices would be preferable in order to assess the wider features of the entire space‐economy. This article constructs global indices from the local indices already used in assessing localization and specialization. Global localization and global specialization are shown to be identical when all local indices use the dissimilarity logic. Two‐digit standard industry codes manufacturing data, taken from the U.S. during 1958–1995, are used to illustrate the results. The values of these global coefficients, like their local constituents, are shown to vary with geographic scale. The discussion addresses spatial distributions (evenness) but not geographic arrangements (clustering).     

A new descriptive method for fruit firmness changes with various softening patterns of kiwifruit

We have proposed a new interpretation of fruit softening. This was accomplished by generating a hypothesis that probabilities of decay of fruit structure obey the Weibull probabilistic model that has been used in the field of reliability engineering. The elasticity of individual kiwifruit after harvest was continually and nondestructively measured until decomposition by using a laser Doppler vibrometer. The obtained decreasing pattern of elasticity of individual fruit was complex, diverse, and inhomogeneous. Nonetheless, it was satisfactorily explained by a tandem combination of 2 Weibull models involving 4 types of parameters: “shape” related to probability; “scale,” to velocity of decay; “location,” to time lag; and “mixing ratio,” to contribution of the 2 models. Averages of location, shape, and mixing ratio parameters obtained by the measurement of 33 fruit were significantly different between the 2 models, but the scale parameter was not. The results suggested that the complex softening patterns of individual kiwifruit could be described using the tandem model of Weibull distribution, and that the softening process of kiwifruit consisted of at least 2 independent decay phases that are characterized by 2 of 5 parameters: location and mixing ratio. Commencement of the first decay phase could be caused by ethylene treatment after harvest, and the second one spontaneously triggered after a certain time lag.     

Continuity and Change in an Old Industrial Region

Analysts have debated the extent to which recent economic changes represent a continuation of earlier patterns or a fundamental shift to a new industrial order. We trace and extend the spatial implications of this debate for a mature industrial region, the Ohio River Valley, part of the American Manufacturing Belt, for the 1980-90 period. The paper builds on recent research arguing that such regions had a diverse, rather than homogeneous, space-economy. Empirical findings clearly demonstrate diversity of economic structures, sectorally and spatially, emphasizing both continuity and change in an old industrial region, and the totality of economic activity rather than specific sectors identified with the rise or transformation of industrial capitalism. In terms of change, aggregate trends follow national ones, but do not wash evenly over the Ohio River Valley. Nor do they mirror, when considered at a sub-regional scale, patterns indicated by de-industrialization and post-Fordist transition frameworks. Findings provide implications for elaborating or augmenting these perspectives, and types of research needed to accomplish the task.     

The launch and evolution of a technology‐based economy: The case of Austin Texas

This paper uses the lens of institutional theory to explain the launch and evolution of Austin, Texas's technology‐based economy. The case underscores the importance of context, contingency, and the evolution of key local development organizations in explaining how regional economic development trajectories can change and evolve. The case history provides insights into how economic development networks form and operate to “set off” processes of industrial specialization and agglomeration and how they can promote successful adaptation to change in technology and industrial structure. The Austin story further suggests a “stage” process of regional technology‐based evolution where the development of industrial agglomerations linked to a substantial local research base is seen as a necessary precursor to increasing endogenous innovation and start‐up activity. Successfully navigating these stages is bolstered by the formation of institutions and networks that are durable, strategic, and adaptive, and which, at the right time, recognize and support entrepreneurial firm development to help sustain technology‐based growth.
