ABSTRACT A public policy response to global competition is the creation of a geographic concentration of innovative activity (regional innovation systems [RIS]) that will enhance metropolitan economic development through knowledge spillovers, product development, and new firm spin‐offs. This article identifies three types of RIS in the thirteen southern states based on a cluster analysis of twenty indicators of innovative and entrepreneurial activity. Next, regression analysis is used to determine if the 1990–2000 growth rates of nonmetro county population, employment, and earnings were related to proximity to an RIS after controlling for other county characteristics associated with local economic development. The research findings indicate that nonmetro counties near an RIS experienced more rapid population and employment growth; however, changes in nonmetro growth rates varied by type of regional innovation system. In addition, proximity to an RIS had a stronger impact on nonmetro population change than on nonmetro job growth. 相似文献

Non‐metropolitan areas of the U.S have experienced significant structural economic changes in recent decades. These changes have raised concerns that some non‐metropolitan workers may face significant costs to employment displacements associated with economic adjustments. This paper explores the roles that linkages to metropolitan labor markets, area labor market conditions, and individual attributes play in determining the rates of exit from unemployment to employment among non‐metropolitan area residents. Adjacency to a metropolitan area is found to significantly increase transition rates from unemployment to employment among displaced non‐metropolitan workers, but local economic conditions are found to have relatively weak or insignificant effects on transition rates. Also, lack of post‐high school education and minority status both significantly reduce rates of exit from unemployment in non‐metropolitan areas following employmentdisplacement. 相似文献

ABSTRACT Targeting industry clusters for economic development has become popular despite the lack of empirical evidence about the spatial scales over which various clusters agglomerate. This paper identifies twenty manufacturing industry clusters from a principal components analysis of interindustry patterns of trade and measures the spatial employment concentration of each cluster's plants within a polycentric framework. Two to eight centers of employment concentration are detected within the Southern California region for each set of trade linkages. Our spatial half‐life measure reveals that half of a cluster's employment in associated establishments is located within a typical range of eight to twelve kilometers (about 5–7.5 miles) to the nearest employment center or subcenter for the particular cluster. Furthermore, employment in seventeen of the twenty clusters is found to be more spatially concentrated than manufacturing employment as a whole, suggesting that geographic proximity is important to interindustry linkages in the Southern California economy. More important, the spatial concentration across industry clusters varies considerably within the metropolitan area, implying that economic development practitioners should consider local context and adapt industry cluster theories to the specific advantages and disadvantages of their immediate locality. 相似文献

ABSTRACT Population, employment, and income changes in a region comprised of eighteen nonmetropolitan counties of Maine, New Hampshire, Vermont, and New York are described using Bureau of Economic Analysis data covering 1970 to 2000. Changes at the county level are examined as net differences using pooled cross‐section time series analysis. The specific focus of the empirical analysis is the effect that environmental amenities have in population and economic change. Empirical results indicate that a county's relative endowment of environmental amenities has positive economic change effects, but only when the county is relatively accessible as well. Further, the environmental amenity effects vary in their temporal consistency, even when accessibility is taken into account. In general, however, the reported results support the proposition that even relatively moderate environmental amenities can hold positive effects for economic change. 相似文献

ABSTRACT This paper examines the relationship between U.S. metropolitan county employment growth and poverty. Differential job growth–poverty linkages are found across metropolitan size and type of county. Own‐county employment growth significantly reduces central‐county poverty in large metropolitan areas relative to suburban county poverty. Compared with larger metropolitan areas, broader metropolitan‐wide job growth has more poverty reducing benefits in medium and smaller metropolitan areas, suggesting fewer metropolitan‐wide job‐accessibility constraints. The results suggest that targeted place‐based efforts to spur job growth may help reduce poverty. 相似文献

Shift‐share analysis is used to examine the role of spatial structure on changes in regional manufacturing employment, in contrast to the traditional focus of shift‐share studies on the role of industrial structure. It is argued that changes in a region's space‐economy can be understood not only in terms of the economic subdivisions of the region but also in terms of the contribution of its spatial subdivisions. The latter is illustrated by means of a case study of the contribution of different types of local area to changes in regional manufacturing employment in Japan. Each region was subdivided into four types of local area based on population density. The analysis covered the period from 1981 to 1995, a time of major transformation in Japan's space‐economy. The shift‐share model was also used to estimate the impact of local area output and productivity on changes in regional employment. In general, the results show that there was a progressive underdevelopment of the core regions, associated with falling output and productivity. The country's peripheral regions were characterized by development, associated with rising output and productivity. Atthe local scale, however, the picture is far more complex. Types of local area contributed to regional employment change in very different ways, with respect to both time, region, and output/productivity. The contribution of local spatial structure to the regional space‐economy of Japan is fundamentally fragmented and uneven. 相似文献

ABSTRACT Many counties in the mountainous areas of the western U.S. are experiencing rapid growth in population and income, even though extractive industries that served historically as their primary economic base are in decline. The purpose of this paper is to establish statistically the spatial determinants of population, employment, and income densities in 86 rural mountain counties and any changes in those determinants between 1985 and 1994. The results of this analysis indicate that densities are oriented to regional metropolitan centers and critical amenities such as ski areas, national parks, and universities or colleges. Negatively sloped density gradients with respect to distance from regional metropolitan centers suggest that the densities of settlement patterns beyond metropolitan boundaries are analogous to those within metropolitan areas relative to urban centers. In short, a tension apparently exists in locational choice; residents of the Mountain West desire to live near the beauties and amenities of the mountain landscape but do not want to entirely sever their urban ties. Because amenities are the primary attraction of mountain counties rather than employment in locationally dependent industries, at least some migrants must have relatively footloose forms of income. 相似文献

We test if remoteness of a county is one of the environmental factors that contribute to obesity. First, we employ geographically weighted regressions (GWRs) that allow us to observe local or regional patterns. We find that county obesity rate is spatially non‐stationary, remoteness affects county obesity rates, and there are spatial heterogeneities in how distance affects county obesity rates. Next, we refine our estimates of the effect of remoteness on county obesity rate using a random effect model that accounts for county‐level unobserved heterogeneity. Even after accounting for these heterogeneities and state fixed effects, we find measurable impact of remoteness on county obesity rate. Splitting the sample into metro and non‐metro counties, we find that remoteness matters more for the obesity rates in the metro counties. 相似文献

Harrington and Campbell (1997) previously illuminated the pattern of producer services' suburbanization in the Washington, D.C., metropolitan area between 1970 and 1992. Their results showed producer services growing at a faster rate at locations farther from the central city. We revisit the topic utilizing data from 2004 to 2010, assessing not only changes in the distribution of producer services since their work, but also the impact of massive increases in defense spending on producer services' growth throughout the first decade of the twenty‐first century. Multivariate linear regression is used to estimate per capita growth of producer services employment using six independent variables. Our results reveal producer services employment during the time period has grown significantly more quickly in the urban D.C. core than the outer suburbs, contrary to Harrington and Campbell's research. Additionally, we find per capita producer services employment is self‐limiting over the study period: locations with more producer services employment in 2004 experienced significantly less producer services growth over the period. We find federal procurement has no correlation on producer services overall, with limited effects on some subsectors. Analyzing a select group of producer services subsectors revealed that no sectors followed the overall model exactly, suggesting that targeting producer services for growth must be done carefully. None of our models show employment diversity to be a factor in differentiating economic growth at the intra‐metropolitan level. 相似文献

To respond to the problems that the previous research mainly targeted the poverty at larger scale and ignored individual effect or contextual effect during exploring poverty contributing factors, we attempt to use spatial cluster analysis and multilevel linear regression model to target the poverty at village level from the perspective of spatial poverty, so as to identify where the poor villages are, and why they are so poor, thereby targeting poverty interventions. Specially, we adopt four types of spatial cluster indices to detect the spatial aggregation distribution of villages, and design HLM model to examine the poverty contributing factors from both village level and county level. The case study from Wuling contiguous destitute area show that: (1) The overall distribution shows a spatial pattern of large scattered but small concentration, scatters‐polar core‐axis‐clump coexisted. (2) Poverty contributing factors at village level from high to low are: per cultivated area, safe drinking water access ratio, terrain type, suffered frequency of natural disasters, road access ratio, and distance from the nearest town’s bazaar. The contribution degree of county‐level factors to the villages’ poverty from high to low are: second gross enrollment ratio, per capita GDP. (3) 45.1% of the difference among the villages’ poverty degrees comes from the development differences among poverty‐stricken villages themselves, and 54.9% from that among counties they belong to. Contributing factors at village level account for 61.4% of the variation of village‐level independent variables, and factors at county level contributed to 65.3% of the variation of county‐level independent variables. 相似文献

Should an economic development strategy target the business services industry to insulate the local economy from the business cycle? The relationship between business services employment (SIC 73) and measures of the business cycle is analyzed at national and metropolitan-area levels. At the national level, certain components of business services are not immune to the business cycle while others are. At the metropolitan level, certain characteristics of the metropolitan area and its industrial structure are identified which would result in business services employment being procyclical or not immune to the business cycle. 相似文献

ABSTRACT. Washington DC is the center of the nation's ninth largest metropolitan area (PMSA), home to 4.4 million people and 2.9 million employees in a web of 25 separate, autonomous municipalities spanning three states and the District of Columbia. As such, the region is a good place to analyze the pattern of suburbanization of producer service employment over the past 25 years. In addition to overall suburbanization, the metropolitan area has seen changes in the nature and role of its dominant economic force, the federal government. Direct federal employment has stagnated while federal contracts to private companies have soared. Producer service employment seemed to increase in importance in jurisdictions away from the region's core, simultaneous with increases in total employment, following increases in federal contracting, and independent of increases in federal employment. These trends have affected the growth of producer service employment across the metropolitan area, encouraging their suburbanization. By subjecting our initial models to sub-sector data and analysis of temporal trends in the coefficients, we uncover the uniqueness of legal services and additional evidence of suburbanization over time. 相似文献

A U.S. county workplace‐to‐workplace or latent migration data set is generated from overlapping migration and commuting networks. The latent migration network is the estimated number of movers between places of work, which is then compared with the actual number of migrants between places of residence. This allows both employment‐related and amenity‐related migration and pull/push factors as causes of migration flows to be identified and contrasted. Certain counties and cities that are not important migration destinations (e.g., with <200,000 net in‐migrants between 1995 and 2000) according to official data are in fact important targets when additional in‐migrants who commute into surrounding counties also are considered. An econometric analysis is then used to examine whether different regressors have different effects on the residence‐ versus employment‐based migration patterns. This is a first assessment of whether or not the proposed approach has merit. Results are consistent with prior expectations regarding the factors that would motivate latent versus actual migration. 相似文献

We examine the effects of individual plant and local characteristics on explaining survival of manufacturing plants over the last two recessions. We link the establishment‐level Rural Manufacturing Survey to longitudinal establishment employment records (Quarterly Census of Employment and Wages) and examine establishment survival using a Cox proportional hazards model. We find that independent and smaller plants were most likely to survive this period of manufacturing decline (1996–2011) and their survival was more affected by local context than establishments which are part of a multi‐plant firm. Among independent plants, we find that those in metropolitan counties had higher hazard rates despite finding access to local markets being a driver of survival. Plants located in more competitive counties had higher hazard rates. 相似文献

ABSTRACT Attempts to differentiate regions from one another, whether in social, demographic, or economic terms, have led to the development of numerous indices to summarize the economic composition of regions. This study revisits classic indices of industrial diversity to evaluate their applicability for benchmarking local and regional economies. Specifically, we explore a multivariate extension of these diversity indices for measuring concentration in an effort to evaluate their ability to accurately depict spatial relationships of county level resources for the contiguous U.S. The relative abilities of the classic indices are compared to a developed measure of resource concentration, the County Similarity Index (CS‐Index), which represents a computationally simple and flexible alternative to these indices. Results suggest the CS‐Index produces superior results to the indices evaluated, particularly with regard to the spatial relationships of county resource concentrations, which are quantified using global and local indicators of spatial association. 相似文献

The capabilities of central office (CO) telephone switches in four southeastern states (Kentucky, Mississippi, North Carolina, and Tennessee) provide detail on spatial variation in telecommunications technologies. A proposed six‐level hierarchy of switch capability was used. Switches with digital capability are concentrated disproportionately in metropolitan areas, largely in response to larger numbers of business establishments. The overall picture in the Southeast is one of tremendous variation—variation across states and variation within the four states being studied. Rural (nonmetro) counties generally, but not always, have both fewer switches overall and fewer switches with digital capability. North Carolina and Tennessee, the two most urban of the four states, also have seen the greatest entry by new telecommunications competitors. These two states have the largest percentages of advanced (digital) switches in both metro and rural counties. At the county level, the number of switches is primarily a function of a county's population but, even more significantly in three states, of the number of business establishments in the county. On the whole, it is residents of metropolitan—not rural—areas who are most likely to be served by newer forms of digital telecommunications. 相似文献

Destination Choice of the Newly Arrived Immigrants to the U.S. from 2000 to 2005–2007: A Multivariate Explanation for Immigrants from Top Source Countries 下载免费PDF全文
下载免费PDF全文 Using the PUMS files of the 2000 U.S. Census and 2005–2007 merged ACS data, we study the metropolitan destination choices made by newly arrived immigrants from seven top source countries between 2000 and 2007. Using a multinomial logit model, we find that the dispersion of new immigrant groups varies by origin, although all groups were subject to 1) the attraction of co‐ethnic communities, and 2) the positive effects of labor market conditions in the destination (especially the employment growth rate). However, co‐ethnic concentration is much more important than labor market conditions in the destination choice decision, particularly for the poorly educated. Conversely, there is a strong negative effect of co‐ethnic concentration on highly educated new immigrants, revealing a dispersed geographical pattern of these highly educated immigrants. We also find the importance of employment share growth rate for highly educated immigrants which suggests that they are more sensitive to the upward employment structure at the destination than a specific job growth rate, and they may not be attracted by a metropolitan area with a low‐quality employment structure, despite whether there was an increase in high‐level jobs. 相似文献

Despite an increase of 200,000 jobs in business and professional services in the Atlanta metropolitan area between 1982 and 1997, the central city saw employment as a percentage of these services drop by approximately 20 percent. Most growth occurred in the northern suburbs, resulting in a dispersed distribution of business and professional services in Atlanta. To understand the spatial distribution and suburbanization of business and professional services in Atlanta, regression analysis was carried out for 1982 and 1992. Flexible female workers, corporate headquarters, well –educated professionals, and highway access turned out to be important location determinants, with the latter two being increasingly responsible for the suburbanization of business and professional services. 相似文献

Coastal Bangladesh is highly vulnerable to climate change and salinisation; hence, farm‐level adaptation is critically important. Farmers' perceptions of and responses to environmental change were investigated in two villages in Khulna District. Perceived environmental trends included increases in temperature, extreme weather events, soil toxicity, erratic rainfall and scarcity of water for irrigation. Perceptions of climate trends were consistent with measured trends in Khulna. On‐farm adaptation strategies included adjusting planting dates, excavating trenches in rice‐fields, adopting new crops, salinity‐reducing technologies, livestock‐rearing and home‐yard cropping. Non‐farm adaptation strategies included wage employment, short‐term migration and self‐employment. Adaptation was facilitated by income‐earning opportunities, training, and credit, and impeded by lack of access to water, markets, capital, and extension services. Farmers suggested policy support for dissemination of stress‐tolerant cultivars, access to irrigation, and price stabilisation or crop insurance to assist adaptation. While the study shows an impressive degree of awareness and adaptation, external support is needed to increase adaptive capacity. 相似文献

ABSTRACT Despite the fact that nonemployment income makes up approximately one-third of all personal income, its impact on local area economies has not been closely examined. This study uses Michigan county data to examine the impact of nonemployment income on nonbasic income over a twenty-seven-year period. This impact is compared to the impact of basic income by employing regression analysis to estimate comparative multiplier effects for both types of income. Nonemployment income is found to have a significant impact on nonbasic income, particularly in metropolitan and nonmetropolitan urban counties, where its impact appears to be stronger than that of basic income. 相似文献
