Research on the impact of the regional environment in the very early phase of the business start-up process is currently limited. This paper contributes to the literature by analysing the influence of regional factors on the formation of entrepreneurial intentions within the theory of planned behaviour (TPB) framework. The rationale is based on the previous literature which posits that regional conditions have implications for individual perceptions, which, in turn, constitute the foundation of the three antecedents of intention in the TPB model: attitudes, subjective norm and perceived behavioural control. A multilevel analysis based on a random sample of 834 Finnish working-age individuals, combined with the official national statistics at the municipality level supports the proposition that regional conditions have an indirect impact on the intent to become an entrepreneur. The population density, the level of education, income and wealth and the rate of public and manufacturing sector employment of a region are found to moderate the individual formation of entrepreneurial intentions. This study supports further development of the theoretical understanding of entrepreneurial intentions by demonstrating that regional characteristics are important moderating influences in the TPB model. 相似文献

This paper describes a case study of path-dependent industrial development in a specialized medium-sized region characterized by a specialized high-tech industry cluster, located near Norway's capital, Oslo. The case study examines the path-dependent process of new industry arising from technology-related industries through three main branching mechanisms: entrepreneurship, mobility, and social networks. More particularly, the study explores the extent to which regional branching mechanisms relate to different path-dependent processes of path extension, path renewal, or path creation. The case study of industrial development in a medium-sized region that critically examines the concepts of path dependence, and argues that specialized medium-sized regions follow different path processes from core regions due to regional branching that does not happen automatically but instead may require policy action and external investment to avoid stagnation or negative lock-in. 相似文献

Evaluating the role and performance of China's participation in Global value chains (GVCs) has been a hot policy and research issue in recent years. However, most GVCs-related literature about China focuses on country-to-country relations; less attention has been paid to China's domestic value chains (DVCs). GVCs should have their domestic foundations since strong linkages across domestic firms and regions can improve productivity through gains from specialization, which make domestic industries more competitive in GVCs in turn. This paper applies the so-called Trade in Value-added (TiVA) concept and the decomposition of domestic-regional trade in TiVA terms to re-measure the inter-industrial and interregional linkages in China's DVCs. We show that TiVA-based measures can significantly enrich our understanding on both the structure change of China's regional economy and the position and participation degree of Chinese regions in DVCs. 相似文献

世界遗产保护与区域旅游可持续发展关系的《周易》解读 总被引:1,自引:0,他引:1
<周易>是中华民族古代思想的结晶,是中国文化的核心和灵魂.其中"易"的思想、"阴阳平衡"论,"天人合一"观,对于正确处理世界遗产保护和区域旅游可持续发展的关系具有重要指导意义.目前,世界遗产保护和区域旅游可持续发展存在着阴阳失衡、忽略了易的思想、违背天人合一观等三个问题.我们应从<周易>哲学思想得到启示,立足长远.采取有效措施,保护世界遗产,实现区域旅游可持续发展. 相似文献

估计和预测城市居民收入变化对家庭能源消费碳排放的影响,对城市家庭消费部门构建低碳能源供应体系,应对气候变化具有重要意义。论文首先估计了中国284个地级以上城市的家庭三类能源消费的直接碳排放量,建立了面板固定效应模型来识别城市家庭能耗碳排放增长和变化的驱动因素。研究结果表明:城市居民收入的快速增长与储蓄水平的提高对于家庭碳排放有显著影响;城市家庭收入和储蓄的增加会抑制家庭燃气碳排放的产生,但对于城市家庭用电碳排放和城市家庭采暖碳排放,则表现出显著的推动作用。此外,研究还发现了家庭碳排放的影响因素存在显著的区域异质性。 相似文献
