As the subjective and objective factors that influence corporate behaviours, political region and firm location are of great importance to environmental information disclosure (EID). With spatial and political geography as a research perspective, this article makes a study by using the samples of manufacturing listed companies from 2009 to 2011. As a result, we determine that regulatory distance and political geography had negative effects on EID, while political geography weakens regulatory distance’s function. After considering an enterprise’s administrative rank, we determined that when the rank is higher, regulatory distance has negative effects on EID; when the rank is lower, the effects are the opposite. Regarding political geography, it always weakened the regulatory distance’s function. Moreover, the effects are significant only when the enterprises had low governmental regulation. The study shows the effects that firm location and political geography have made on EID. At the same time, this study also gives theoretical and empirical evidence to the necessity of raising governmental regulatory effectiveness.  相似文献

This article reflects on aligning leisure research with the local foods movement while placing the local foods movement into the larger framework of sustainability and the fields of leisure and recreation. The local foods movement has persisted during difficult economic times; growth in local foods venues and young people endeavoring to establish small-scale sustainable farms continues to flourish. Given the history of leisure research and its continued success alleviating participation barriers and constraints, the need for leisure researchers to focus on local food systems is imperative and timely. This essay highlights the notion of leisure in living through local foods and the serious leisure aspects of small-scale sustainable agriculture. This article also encourages leisure researchers to explore and assess the relationships between the local foods movement and small-scale farming as embedded in the larger framework of sustainability.  相似文献

地方立法中的申请审批条款在一定程度上决定着我国农村宅基地申请审批的实际状况。通过对地方立法文本中关于申请审批的立法模式和内容构成的统计分析,发现我国目前宅基地申请人的资格不一,审批中农村集体经济组织主体位置虚缺,而且宅基地立法层级很低,立法清理工作不及时。我国今后应明确农村集体经济组织成员的内涵,强化宅基地所有权人在审批中的作用,制定统一的《农村宅基地使用权法》。  相似文献

Abstract

This study identifies a gap in research concerning how small and medium-sized enterprises (SMEs) can benefit from pursuing locally (rather than globally) oriented internationalization strategies. Becoming overly dependent on one single foreign market could potentially reduce the inflow and diversity of new knowledge that can serve as input for new product development. This study discusses how this risk can be minimized. In this endeavour we create a theoretical model that investigates how the local sales concentration and relationship-specific commitment of SMEs relates to new product development. To do this we draw on the behavioural internationalization process framework. The theoretical model is tested on an effective sample of 188 Swedish SMEs. The results show that relationship-specific commitment mediates the effect of local sales concentration on new product development. The implication is that investments which enable collaboration in important business relationships are crucial requisites for keeping firms innovative and in pace with market fluctuations. The findings thus contribute to international business literature by showing that a local market scope of operations combined with a relationship orientation are beneficial for new product development in international SMEs.  相似文献

由于业主对建筑结构使用功能的需求,往往在剪力墙开设新的洞口,开洞后将大大降低剪力墙的抗剪能力,对于新建工程可以对剪力墙洞口部位进行增加暗柱、暗梁或加强钢筋来补强剪力墙的抗剪能力。而对于剪力墙开洞改造工程来说,开洞后因无法增加暗梁、暗柱对剪力墙提高承载能力。因此,在开洞后就必须进行加固,现就对传统的加固方法进行分析,并根据实际施工情况提出新的方法。  相似文献

This article presents a comparative analysis of the perceived usefulness of performance information by managers in local authorities in Italy and Spain. Italy and Spain have similar cultural and administrative characteristics and in both countries there are external requirements (from central government) to adopt performance indicators. The adoption of performance indicators was found to be almost symbolic in both states.  相似文献

ABSTRACT

Many retailers have been expanding into foreign markets, although not all such attempts at internationalization have been successful. This study examines the actions taken by Chilean retailers that negatively affected the operations of Home Depot, Carrefour and J.C. Penney in Chile. The results show that the strategies employed by local companies have consisted in: (1) becoming informed about the company's strengths and weaknesses, while imitating its best practices; (2) deepening their own market know-how and hiring high-level executives to lead defensive strategies; (3) opening stores in strategic places in order to win advantages concerning location; and (4) investing in technology and the training of employees. The overall effect on the market has been one of concentration and consolidation of the retail industry.

RESUMEN. Muchos retailers se están expandiendo a mercados extranjeros, sin embargo no todos los intentos de internacionalización son exitosos. Este estudio examina las acciones desarrolladas por retailers chilenos que afectaron negativamente la operación en Chile de Home Depot, Carrefour, y J.C. Penney. Los resultados de esta investigación muestran que las estratégicas empleadas por las empresas locales consistieron en (1) informarse en forma anticipada las fortalezas y debilidades de la empresa extranjera e imitando sus mejores prácticas, (2) fortaleciendo su conocimiento del mercado y contratando ejecutivos fuertes para liderar la estrategia defensiva, (3) apertura de locales en ubicaciones estratégicas para bloquear ventajas de localización, y (4) inversión en tecnología y capitación a los empleados. Los efectos sobre el mercado total fue de mayor concentración y consolidación de la industria.

RESUMO. Muitos varejistas têm expandido seus negócios para mercados estrangeiros, embora nem todas estas tentativas de internacionalização tenham sido bem sucedidas. Este estudo examina as aç[otilde]es implementadas por varejistas chilenos, as quais afetaram negativamente as operaç[otilde]es da Home Depot, Carrefour e J.C. Penney no Chile. Os resultados mostram que as estratégias empregadas pelas companhias locais consistiram em: (1) informar-se sobre os pontos fortes e fracos da companhia, ao mesmo tempo em que replicavam suas melhores práticas; (2) aprofundar o conhecimento a respeito de seu próprio mercado e contratar executivos de alto nível para liderar estratégias defensivas; (3) promover a abertura de lojas em locais estratégicos com o objetivo de conquistar vantagens relativas à localização; e (4) investir em tecnologia e no treinamento de funcionários. O efeito global desses movimentos no mercado tem sido o de promover a concentração e a consolidação da indústria varejista.  相似文献
