New businesses are highly involved in innovative activity, which enhances worker productivity and leads to increased economic output. This paper investigates the effects of industry concentration on the incidence of new business openings in the 5,504 Maine county‐industries. Empirical findings indicate that new business activity increases with the number of incumbent establishments in a county‐industry and its concentration level relative to the U.S. economy. Model simulations show that raising county‐industries, with no initial industry presence, to concentration levels similar to that of the industry in the U.S. economy results in a 1.7 to 8.9 percent increase in the expected number of business openings over a three‐year period. Empirical results also suggest that industry clusters comprised of young and small establishments are more conducive to new business formation than clusters made up of mature and large companies. 相似文献

The Marketplace Fairness Act (S. 743) recently passed by the U.S. Senate may portend a national move toward states imposing sales taxes for business‐to‐consumer e‐retail purchases. While much of the policy debate surrounding this question has focused on trade creation versus diversion, there are likely distinct compositional effects at the state level, which will affect both economic activity and tax revenue. Consumers are clearly hurt by an online sales tax. However, such a policy would seemingly benefit state tax coffers, as well as traditional brick‐and‐mortar retailers and their employees. This paper uses a computable general equilibrium model approach to get a better understanding of the state‐level income, employment, and tax revenue effects of such a policy shift, in particular the likely tradeoffs between these three traditional economic targets across reasonable ranges of price elasticities. 相似文献

This paper examines the relationship between external knowledge sourcing and a diverse set of innovation outcomes in rural and urban establishments in the U.S. Existing studies in the broader knowledge management literature principally examine firms in a single industry, overwhelmingly rely on patent data to proxy for innovation, and cannot account for the innovations of businesses in rural American markets. By addressing these limitations using data from the 2014 Rural Establishment Innovation Survey of the USDA's Economic Research Service, this research provides novel insights into how externally acquired knowledge by American establishments may support innovation. Results of the analysis suggest that external knowledge sourcing may specifically promote product, process, and green innovation in U.S. firms. While collective results when external sources of information are divided by industry orientation fail to show that sources outside of a firm's industry play a dominant role in the innovation processes of American establishments in general, findings provide evidence for an outsized impact of these relationships within rural establishments specifically and suggest that external knowledge sourcing from extra‐industry organizations is most critical for promoting successful innovation in rural firms. Results additionally indicate that knowledge sourcing from non‐local organizations may be more important for supporting innovation in rural compared to urban markets. 相似文献

Do exporters and foreign‐controlled establishments pay their workers higher wages than non‐exporters and domestic‐controlled establishments? This paper draws on an employer–employee data set to explore the existence of exporter and foreign‐owned wage premiums in the Canadian manufacturing sector. Results from wage regression models reveal that, on the whole, exporters and foreign‐controlled plants do pay higher wages than non‐exporters and domestic‐controlled plants. These results hold even after controlling for other plant and worker characteristics, although the wage differentials are substantially smaller. Furthermore, while the impact of foreign ownership on wages is found to be widespread across industries and regions, that of exporting is not. At the industry level, the wage effects of export‐market participation are strongest for workers in plants belonging to scale‐based industries; regionally, they are strongest in Quebec and British Columbia. 相似文献

This article provides a comparative analysis of factors influencing the out-of-state export decisions of establishments within selected groups of services-producing and manufacturing industries. Data were gathered through a mail survey of establishments located in both rural and urban areas of five Midwestern states. The proportion of sales exported was specified as a function of establishment and location characteristics and estimated using Tobit analysis. Results of the study indicate that both establishment and location characteristics are important predictors of the export decision and confirm that establishments in some services-producing industries are able to enter and compete in out-of-state export markets. Similar factors were found to influence the export decisions of services-producing and manufacturing establishments. Results suggest that services-producing establishments in the group of industries may not be footloose with respect to locational choices. 相似文献

This paper uses the Longitudinal Research Database (LRD),a unique, detailed, plant‐level database that covers the entire U.S. manufacturing sector in five‐year intervals to examine how the manufacturing sector in Appalachia has evolved over the past thirty years (from 1963 to 1992). The research focuses on three questions:1) Is the Appalachian Region attracting new manufacturing plants at the same rate as the rest of the country? 2) Does Appalachian manufacturing employment exhibit low wage, low productivity characteristics, compared with the rest of the country? 3) Is Appalachia still heavily reliant on branch plants? The results show the manufacturing base of Appalachia in 1992 looks very much the same as it did in 1967. Compared to the rest of the country, Appalachian manufacturing is still more reliant on branch plants and is characterized by lower wage and lower productivity establishments. This result is not due to a lack of entry—manufacturing plant entry rates and manufacturing job formation associated with entrants in Appalachia are only slightly lower than for the U.S. as a whole. Job destruction rates caused by exits are actually lower than in the U.S. as a whole. 相似文献

Shift‐share analysis is a decomposition technique widely used in regional studies to quantify an industry‐mix effect and a competitive effect on the growth of regional employment (or any other relevant variable) relative to the national average. This technique has always been subject to criticism for its lack of theoretical basis. This paper presents a critical assessment of the methods suggested by Dunn and Esteban‐Marquillas and proposes a new shift‐share method, which separates out the two effects unambiguously. By way of illustration, we provide an application to manufacturing employment in the Belgian provinces between 1995 and 2007. 相似文献

This paper investigates intra‐urban population and employment shifts over 1980–2000, using the Cincinnati Metropolitan Area as a case study. Population and employment are disaggregated by ethnicity (White, Black, Others) and industry (10 sectors) to better capture different location behaviors. Inter‐industry relationships are considered when constructing accessibility variables. Additional diversity, locational and socio‐economic variables are included. A location‐specific index of air quality is also considered, as a proxy for environmental quality. A structural equation model is specified to account for the dynamic interactions between populations, activities, and air quality. The results reveal strong interactions between ethnic groups, confirm the existence of agglomeration effects, and suggest that diversity has positive effects on both firms and households in both periods (1980–1990 and 1990–2000). For firms, better access to their potential customers and employees is more important than better access to their input–output sectors. Better air quality attracts population, which in turn worsens it. The results reveal changing dynamics, from 1980–1990 to 1990–2000, for different population and activity groups, and suggest that overall, firm location behaviors are more stable than household behaviors. 相似文献

University‐industry‐government triple helix relationship and regional innovation efficiency in China
By utilizing panel data of provinces in China from 2012 to 2018, this paper measured innovation efficiency of each regional innovation system and the triple helix relationship of the university‐industry‐government system, then, empirically investigated the influence of the triple helix relationship on regional innovation efficiency. It has been found that: (1) the regional innovation efficiency in China increases slightly year by year, the regional differences are obvious, and university–industry bilateral cooperation is the tightest; (2) cooperation between universities and industries is most beneficial to improve regional innovation efficiency, cooperation between universities and governments significantly promotes scale efficiency in the long run, cooperation between industries and governments significantly promotes regional innovation comprehensive efficiency and pure technical efficiency, meanwhile inhibits scale efficiency, coordinated relation among universities, industries, and governments is beneficial to improve regional innovation comprehensive efficiency and scale efficiency. The research results provide useful theoretical support and policy enlightenment for improving regional innovation efficiency. 相似文献

In recent decades, while place‐based policies and local development have attracted the interest of institutional economic geography, the issue of features of certain industries and how they are shaping and shaped by institutions at multiple spatial scales, has not been taken up sufficiently. This paper, based on a local creative industry—the Shanghai online games industry, which is an essential part of the new media sector, takes issue with it. It explores two aspects, namely how multi‐scalar institutions relate and influence the development of the online games industry in Shanghai and how local firms and entrepreneurs affect local and national institutions. It shows that the three aspects that are related to media sector in general and games industry in particular (i.e., cultural influence, technological significance, and economic value) matter much as they have resulted in diverse industry‐relevant policies and regulations devised by local and national states. Moreover, local firms and entrepreneurs with different capacities and characteristics also differ much in influencing the design of the industry‐specific institutions in the face of institutional voids. 相似文献

ABSTRACT This paper explores possible ways in which growth in Internet retailing (e‐retailing) may affect the spatial distribution of economic activities. After a brief overview of e‐retailing, a categorization of possible spatial impacts is introduced. These include impacts on the retail industry, such as substitution of e‐retail for brick‐and‐mortar retail, impacts on transportation, such as substitution of freight transportation for personal transportation in goods delivery, and pervasive impacts that affect the whole economy. The latter category includes uniform delivered pricing, spatial leveling of accessibility, and marketing strategies that target individuals rather than regions. The question of whether e‐retailing and brick‐and‐mortar retailing are truly substitutes is taken up in the next section, along with potential implications of multi‐channel retailing. The final section of the paper defines some critical research directions. 相似文献

The juxtaposition of oil and gas wells against the Rocky Mountains on Colorado's Front Range provides a picture of the complicated interaction between Colorado's natural resources above and below ground. As hydraulic fracturing has increased oil and gas development—bringing jobs and money to an already highly sought after amenity‐rich area—it has also increased concerns about the impact on natural amenities, such as water quality and mountain views. Using data on housing sales between 2006 and 2014, we estimate how shale development is capitalized into housing prices in a booming market when households are in close proximity to other natural amenities. We find that shale development negatively impacts house prices, more so for houses with private water and houses that are closer to the mountains, but that competition for land along the Front Range has driven up house prices overall in the region. Our results also suggest the policy responses to shale development may differ for growing, amenity‐rich regions. 相似文献

This paper presents some micro‐evidence relevant to the “Porter Hypothesis” on the techno‐economic consequences of Austrian Volatile Organic Compound (VOC) emission standards, the most restrictive of their kind in the world. Using firm‐level survey data and complementing it with highly disaggregated foreign trade data, the paper explores whether the standards had a palpable impact on the competitiveness of Austrian manufacturers of paints, coatings, printing inks, and adhesives, whether compliance stimulated innovation in this industry, whether the standards crowded out other, more productive Research and Development (R&D), and whether compliance efforts gave rise to unexpected benefits of compliance. It finds no unequivocal aggregate impact on the competitiveness of regulated firms, yet does find some interesting variation with firm size. Moreover, the standards appear to have dampened import competition. The standards gave rise to considerable changes in firms’ product range and appear to have accelerated the rate of product innovation in the regulated industry. R&D spending to develop compliant products is found to be very unevenly distributed, mainly due to technological and, to a lesser extent, organizational factors. There is evidence that compliance efforts displaced or postponed existing R&D projects. However, there is also evidence that search for compliant products yielded unexpected and beneficial ideas, knowledge, and competencies. 相似文献

Antioxidants play an important role in adapting plants to abiotic stress by detoxifying reactive oxygen species (ROS). Involvement of antioxidant enzymes in abiotic stress tolerance of highly stress‐tolerant quinoa was studied in a climatic chamber at 6 mOsm (milliosmolar) ionic (300 mm NaCl) and non‐ionic (600 mm mannitol) salts combined with increasing levels of potassium K1 and K2 (6, 12 mm ), respectively. Fifteen days of salt treatment (both ionic and non‐ionic) decreased plant growth (shoot and root fresh weight), stomatal conductance and chlorophyll content index. Furthermore, both forms of salt stress increased the activities of superoxide dismutase, catalase, ascorbate peroxidase and peroxidase up to 2.33‐, 3.98‐, 4.78‐ and 5.55‐folds, respectively, compared to no salt treatment, whereas membrane stability index decreased corresponding to increase in lipid peroxidation (malondialdehyde), with salt treatments compared to non‐stressed plants. However, no significant effect of potassium and salt treatments has been noticed on the maximal photochemical efficiency of PSII. The results suggested that enhanced antioxidant enzymes activity under salt stress could be one of the factors responsible for abiotic stress tolerance in quinoa. 相似文献

ABSTRACT This paper uses a cross‐sectional hedonic pricing model to investigate the relationship between the U.S. Environmental Protection Agency's (EPA) Toxics Release Inventory (TRI) data releases and the prices of single‐family residences within postal zip code areas situated in Omaha, Nebraska's Douglas County. The model employs demographic data from the 2000 Census, toxic chemical release data for the year 2000 from the EPA's TRI database, as well as other pollution variables for each of the zip code areas comprising Douglas County. The model also employs house‐specific data supplied by the Douglas County Assessor's Office on dwelling characteristics for homes sold in Douglas County in the year 2000. The findings indicate that, when controlling for relevant socioeconomic variables, TRI pollutant releases are significant determinants of residential housing values. The results should be of interest to anyone in the real estate industry, including tax assessors, appraisers, mortgage lenders, and property owners. 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

The widespread use of warm‐season turfgrasses in transition zones of Europe, such as northern Italy, has been hampered by the long dormancy periods. To encourage the conversion from cool‐ to warm‐season grasses, research is needed to identify cultivars that exhibit early spring green‐up. A 2‐year study was conducted at the agricultural experimental farm of Padova University from November 2006 to October 2008 to compare water‐soluble carbohydrate and protein content in stolons of four bermudagrass [Cynodon dactylon (L.) Pers.] cultivars and determine their effect on spring green‐up. Samples of ‘La Paloma’, ‘NuMex Sahara’, ‘Princess 77’ and ‘Yukon’ were collected monthly, and water‐soluble carbohydrates (WSC) and crude protein (CP) content of stolons were measured. Dry weight values of WSC and CP for each cultivar were regressed against days needed to reach 80 % green cover in spring (D80). ‘Yukon’ exhibited the highest rhizome dry weight and WSC content during the winter months and was the fastest to reach 80 % green cover. Conversely, ‘Princess 77’ was the slowest cultivar to green‐up in both years. Regression analysis revealed a stronger relationship between D80 and WSC than between CP content and D80. 相似文献

Capturing cluster life cycle with a mixed‐method analysis: Evidence from a French cluster case study
This article contributes to the growing literature on cluster life cycles (CLC) by demonstrating the opportunities offered by a mixed‐method approach. The combination of qualitative and quantitative data is useful both to describe the evolution of network patterns and to provide an understanding of the drivers of CLC. Based on the literature, we rely on a theoretical background integrating the pre‐existing context (cognitive, institutional, and social) in which actors involved in the nascent cluster are embedded, in order to capture the impact of the genesis period on the cluster's subsequent trajectory. The operationalization of this mixed‐method focused on one case study highlights the determining period of the genesis, since CLC is rooted in (a) the building of interpersonal relationships between actors from science and industry, (b) a longstanding specialization in a technological domain, and (c) policy opportunities and guidelines. The cluster trajectory remains driven by the initial policies, the cluster's nascent specialization and the founders' pre‐existing relationships over time, with an evolving role of each type of embeddedness over time. 相似文献

Agricultural e‐commerce clusters are new phenomena that have emerged in rural China. In examining the case of Shuyang County in Jiangsu Province, this paper puts forward an integrated model revealing the formation mechanism of agricultural e‐commerce clusters. The paper shows that the formation of agricultural e‐commerce clusters involves four processes of technology introduction, technology diffusion, quality crisis, and industrial agglomeration based on elements such as industry bases, e‐commerce platforms, network facilities, logistics services, entrepreneurial talent, local government, and market demand. Rural social networks and imitation behaviors promote technology diffusion by reducing the cost of technology introduction, and industrial agglomeration is found in the economies showing a deepening of labor divisions and geographic agglomeration. Throughout the formation process, a quality crisis may occur due to a race to the bottom and the opportunistic behaviors of local farmers. This work suggests that regional e‐commerce development is a systematic project. Governments of developing countries should not only realize the positive impacts of e‐commerce for the development of the agricultural industry but also recognize the premise and logic of how e‐commerce can play a prominent role. 相似文献
