区域创新是一个区域获得可持续发展的根本动力,区域创新能力正日益成为区域经济获取国际竞争优势的决定性因素和区域经济具备竞争优势的重要标志。作为区域经济重要形态的产业集群,以其显著的网络特性成为区域创新系统的理想处所,而构建区域创新系统已经成为各区域实现快速发展的战略选择。本文从产业集群出发,研究创新网络系统的构成及其运行机制,并提出了构建区域创新网络系统的几点思路。 相似文献

企业家行为、企业迁移、产业集群与农村城镇化政策 总被引:5,自引:0,他引:5
文章按照系统自组织理论,采取问卷调查、访谈和分组对比方法,以村镇企业迁移为考察切入点,对我国企业家行为、企业迁移与产业集群之间的联系展开研究。调查研究表明:企业迁移收敛于向区位条件优越、社会化服务和市场体系健全、私有产权保护良好、企业家受人尊重、自然及社会人文环境和谐、地方政府服务好的城镇集聚;企业家控制权与企业迁移呈正相关关系;企业家对产业集群的收益预期和对迁移成本的预期的高低是企业迁移的主要动因。乡镇产业集群政策体系和城镇化政策的要点是:以乡村企业家理性决策和理性迁移为政策立足点,通过公共财政政策的系统配置,以增加公共产品和政府服务、健全市场体系、保护私有产权、尊重企业家人格精神、促进社会人文环境和谐等措施来优化区位和环境,提高乡村企业家产业集群价值的预期,引导中小企业向工业园区或产业集群集聚。 相似文献

北京市各区县劳动力总量分布的产业差别是明显的,其分布是有规律可循的.因此,对于北京市各区县功能区的划分可以站在劳动力产业分布比较优势的角度,采用统计分析的方法,深入分析北京市已经形成的劳动力产业分布规律,从而为城市功能区的划分提供劳动力布局的依据. 相似文献

The evaluation of seeding rules requires the use of probabilistic forecasting models both for individual matches and for the tournament. Prior papers have employed a match-level forecasting model and then used a Monte Carlo simulation of the tournament for estimating outcome probabilities, thus allowing an outcome uncertainty measure to be attached to each proposed seeding regime, for example. However, this approach does not take into account the uncertainty that may surround parameter estimates in the underlying match-level forecasting model. We propose a Bayesian approach for addressing this problem, and illustrate it by simulating the UEFA Champions League under alternative seeding regimes. We find that changes in 2015 tended to increase the uncertainty over progression to the knock-out stage, but made limited difference to which clubs would contest the final. 相似文献

The disproportionate concentration of healthcare professionals in urban areas is a concern in many countries, including Canada. A need to address this rural care gap has driven a large number of government led initiatives worldwide over the years. This paper presents a model that can be used as a tool to examine the efficacy of such policies on the workforce distribution in the long term. A small system dynamics model is employed to simulate the current and future distribution of general physicians at a jurisdictional level. The model represents the transition of general practitioners to provide insight into the dynamics of care provision over time. The movement, and competition, between rural and urban areas is modeled to enable detailed exploration of the ability for proposed measures to alleviate the care gap in the future. Among the tested policies are such commonly used initiatives as financial incentives to rural professionals, promotion of medical education in rural areas, expansion of rural education programs and the engagement of international medical graduates etc. We demonstrate how the model can be used as a tool to determine an efficient and well-chosen combination of policies which can help alleviate the rural care gap in the future, given that some policies are more effective than others alone but also combined with other initiatives. The presented small system dynamics model is tested on Canada's reality, but its simple nature lends itself to easy application to other countries that experience a similar problem. 相似文献

There is a prevalent opinion in the corporate arena that the foreign companies are earning more but are less concerned with reinvesting their earnings in the foreign countries in which they operate and are more concerned in profit appropriations for quick repatriation of their investments by way of declaring high dividend payments. As compared to the foreign companies, domestic companies in India are relatively more concerned for reinvesting their profits and help to trigger the capital accumulation and industrial growth. This practice of comparatively paying higher dividend by foreign companies in India, if proved, supports the view that foreign companies are least concerned with the industrial growth of the country in which they operate. Hence the analyses of the dividend payments and the retained earnings of foreign and domestic firms assume economic importance. Considering the above hypothesis and the importance of the study, this paper made an attempt to empirically test the opinion and bring out any significant differences in the profitability and dividend payments between the two groups often pharmaceutical companies operating in India for the period of last 20 years. 相似文献
