投资额与GDP和财政收入的回归分析及预测 总被引:1,自引:0,他引:1
文章首先运用MATLAB工具对1991-2008年我国GDP、财政收入与投资额等数据进行回归分析,得出固定资产投资与GDP及财政收入的回归模型。其次,分别建立年份对GDP与财政收入的拟合曲线,预测出2009——2010年的GDP与财政收入值,进而推出未来两年的投资额预测值。 相似文献

外商直接投资对中国企业创新的外溢效应研究:基于垂直联系的视角 总被引:1,自引:0,他引:1
利用世界银行对中国的企业调研数据,本文从垂直联系视角考察了FDI对中国企业创新的外溢效应。分析的结果表明,垂直联系有利于企业创新与技术溢出。并且,与水平溢出相比,垂直联系渠道发生的溢出更为显著。对垂直联系影响因素的分析表明,拥有外方合作伙伴、位于工业园或出口加工区、加入商业协会、企业拥有较高的国内市场份额、国内市场进口产品份额较高、受国外教育经理的人数比例越高,这些因素均有利于企业垂直联系的建立。然而,企业的出口倾向对前后向联系的作用相反。 相似文献

本文基于日本的统计数据,利用VAR模型和格兰杰因果关系检验方法,研究政府部门投资、民间部门投资和全产业总资本收益率之间的相互作用。VAR模型分析表明,政府投资对民间投资的影响比较大,两者对全产业总资本收益率的影响都很大且政府投资的影响远远大于民间投资,这些影响关系都较复杂。格兰杰因果关系检验表明,政府投资变化是民间投资变化的格兰杰原因,两者分别是全产业总资本收益率变化的格兰杰原因,而这些变量之间不存在相反方向的格兰杰因果关系。 相似文献

With corporate disclosure of carbon emissions rapidly increasing, the long-standing question remains whether carbon disclosure has any influence on the improvement of carbon performance. Previous studies of environmental disclosure and performance have predominantly focused on whether disclosure is a substitute for poor performance. Little attention has been devoted to the more important question about how changes in disclosure may lead to subsequent changes in performance over time. Following the rationales taken by the legitimacy and management perspectives, we revisit the relationship between carbon disclosure and performance, with a focus on changes that disclosure may (or may not) create. Using a change analysis of Global 500 companies and their carbon emission and disclosure data released between 2008 and 2012, this study finds that the change in carbon disclosure levels is positively associated with a subsequent change in carbon performance (examined through direct and indirect carbon emission intensities). Thus, regardless of whether disclosure has been used as a legitimising tool for prior poor performance, this study confirms that carbon disclosure motivates companies and creates an ‘outside-in’ driven effect for subsequent change and improvement in carbon performance. However, the association between changes in carbon disclosure and performance is relatively weaker in high energy-intensive firms. 相似文献

This paper empirically examines and compares the different theoretical predictions on how adjustment costs, operating and financial leverage influence the value premium. Consistent with Ozdagli (2012), financial leverage plays a dominant role, supported by adjustment costs (which represent the degree of investment irreversibility). Specifically, the observed value premium is driven by the financial leverage differences between value and growth firms, partially neutralized by investment irreversibility. The relation between the value premium and investment irreversibility is contrary to the intuition in Zhang (2005) and Cooper (2006). Operating leverage does not significantly influence the value premium. 相似文献

In this paper, we propose a goal-based investment model that is suitable for personalized wealth management. The model only requires a few intuitive inputs such as size of wealth, investment amount, and consumption goals from individual investors. In particular, a priority level can be assigned to each consumption goal and the model provides a holistic solution based on a sequential approach starting with the highest priority. This allows strict prioritization by maximizing the probability of achieving higher priority goals that are not affected by goals with lower priorities. Furthermore, the proposed model is formulated as a linear program that efficiently finds the optimal financial plan. With its simplicity, flexibility, and computational efficiency, the proposed goal-based investment model provides a new framework for automated investment management services. 相似文献
