This paper contributes to studies on dynamic capabilities (DCs) by showing that a neglected environmental contingency – i.e. the occurrence of a jolt – shapes the DCs–performance relationship. We focus on high-tech entrepreneurial ventures because these are the firms that jolts affect most; in so doing, we also advance the understanding of DCs in the entrepreneurship field. We argue that, in the aftermath of an environmental jolt, the high-tech entrepreneurial ventures that use internationalization and new product development capabilities to modify their resource configuration and regain environmental fit enjoy better performance. Econometric estimates on a sample of 340 Italian high-tech entrepreneurial ventures confronting the consequences of the global economic crisis that began in 2008 confirm that separately using these two DCs has a positive performance effect. This effect is stronger for relatively smaller ventures. Interestingly, despite synergies should arise from the combined use of the two DCs, we do not detect any superadditive effects. 相似文献

金融结构与产业结构的关系一直是学术界的研究热点.文章利用中国1998—2017年的年度数据,构建似不相关回归模型从金融结构规模、效率及深化的角度分析金融结构对产业结构合理化和高级化的影响,建立时变参数状态空间模型描绘了金融结构对产业结构合理化和高级化的动态冲击.实证分析结果表明:金融结构规模提高产业结构合理化水平,促进了产业结构高级化;金融结构效率提高产业结构合理化水平,抑制了产业结构高级化;金融结构深化降低产业结构合理化水平,促进了产业结构高级化.金融结构规模、金融结构效率及金融结构深化对产业结构合理化和高级化的冲击均呈现出时变特征;金融结构对产业结构合理化的影响滞后于其对产业结构高级化的影响.金融结构对产业结构的冲击波幅呈现出前期波动大、后期较为平缓的状态,部分金融结构变量对产业结构的动态冲击呈现出"长尾"现象.当前的中国金融结构已经不适合当前的产业结构,需调整金融结构,以提升产业结构合理化水平和高级化水平. 相似文献

本文基于第一、二次对"无锡、保定农村调查"的资料,分析说明了无锡农村经营式农业的日渐式微,并从出租农地与雇工经营的收益方程、较高工商业发展水平导致的机会成本增加,以及家庭小农场的竞争三个方面分析了经营式农业不发展的原因.我们认为,主要是当地较高但又不足够高的工商业发展水平导致了经营式农业难以发展.较高的工商业发展水平意味着发展经营式农业的高运营成本和高机会成本.不足够高又使得非农产业的需求与人数众多的农业过剩劳动力不相匹配,从而造成了家庭小农场和经营式农场之间的激烈对抗.我们也认为,中国未来的农业农村现代化道路可能会依然呈现出复杂性和特殊性,家庭小农场扮演的角色可能仍然不容忽视. 相似文献

当前乡村治理中乡规民约面临德治退化、自治弱化及法治虚化等现实困境。新乡贤作为乡村社会精英群体,在增强乡规民约的现代性、厚植乡规民约的乡土性及强化乡规民约的权威性等方面具有显著的时代价值,是重塑乡规民约的有益主体选择。实现新乡贤在重塑乡规民约中的时代价值,需要强化乡贤文化的敦风化俗功能、构建乡贤群体的风险防范机制及发挥乡贤组织的协商共治作用。 相似文献

Testing an Integrative Contextual Career Development Model With Adolescents From High‐Poverty Urban Areas 下载免费PDF全文

Variations in the economic recovery rate across the United States have led to even greater chasms that separate the employed, unemployed, and underemployed (DeSilver, 2017 ). Therefore, understanding and supporting the career development of future generations is critical—especially for those who live outside the context of social privilege. The authors examined the applicability of the integrative contextual model of career development (ICM; Lapan, 2004 ) to a sample of 220 adolescents (129 boys, 91 girls) from a high‐poverty urban area. Results indicated that a canonical variate comprising foundational ICM skills (e.g., career exploration, goal setting) predicted a variate composed of ICM outcomes (e.g., self‐efficacy, vocational identity), thus supporting the usefulness of the ICM framework for this population. The skill of setting viable career goals was an especially strong predictor of outcomes. Implications for career counseling with adolescents living in high‐poverty urban areas and directions for future research are discussed. 相似文献

AbstractObjective: To examine rural-urban differences in college students’ cardiovascular risk perceptions. Participants: College students in rural (n?=?61) and urban (n?=?57) Kentucky counties were recruited from November 2012 to May 2014. Methods: This was a secondary data analysis of a cross-sectional study examining rural-urban differences in cardiovascular risk factors. Students rated their risk for developing high blood pressure, diabetes, high cholesterol, heart disease, having a stroke, and gaining excess weight. Chi-square and logistic regression were used for data analysis. Results: Rural students had lower odds of perceived high risk for developing high blood pressure compared to urban students (odds ratio (OR): 0.32, 95% CI: 0.11–0.96) after adjusting for race, sex, and body mass index. This association was not observed after adjusting for healthcare access variables. No other significant differences were observed. Conclusions: Efforts to raise perceived risk for developing hypertension among rural college students may be warranted. 相似文献

Scholars consistently find that parents provide economic support to their young adult children through the transition to adulthood. However, scholars rarely examine whether young adults contribute monetary resources to their parents. To test this proposition, I use the National Longitudinal Study of Adolescent to Adult Health, and the case of “money for living expenses.” Overall, monetary independence is the modal category for all groups. However, when I compare across groups, I find that White young adults with native-born parentage are more likely to report monetary independence, African Americans are more likely to report monetary interdependence and Asian and Latino children of immigrants are more likely to report child-to-parent assistance compared to each other, with SES explaining most, but not all, of these differences. I argue that young adult offspring in non-White families are more likely to provide monetary support to their parents during the transition to adulthood. These transfers may deplete resources for non-White young adults and may exacerbate racial/ethnic inequality during the transition to adulthood. 相似文献

This article examines the dynamics of power and privilege at work in international development through the prism of domestic service for expat aid workers in developing countries. Drawing on ethnographic fieldwork amid aid workers and their domestic staff in Dakar, Senegal, I argue that access to affordable care work greatly enhances the lives of women who work overseas in development. The postcolonial underdevelopment and poverty that aid work addresses is paradoxically critical to the aid workers' own access to affordable care, family balance and the means to do their jobs. I put this insight into the larger scholarly conversation about domestic work and global inequality, including on the Global Care Chain. 相似文献
