两型社会视角下湖南城市土地节约集约利用研究

研究目的:对湖南省城市土地节约集约利用水平进行测度,并针对所存在的问题,提出解决措施,推动湖南两型社会的建设。研究方法:文献资料法、主成份分析法和聚类分析法。研究结果:湖南省城市土地节约集约利用水平差异显著,近年来,湖南城市土地节约集约水平有较大幅度的提高。研究结论:通过加大耕地保护、加强土地利用规划、注重生态环境建设、土地内涵挖潜、提高土地利用强度等措施促进城市土地节约集约利用。     

我国银行体系的稳健性研究——基于面板VAR的实证分析

本文构建了我国银行稳健性指标体系的核心指标组,并合成银行稳健性指数BSI以综合评价我国银行体系的稳定性,检验了银行稳健性与经济增长、信贷规模扩张及资本市场价格之间的面板Granger因果关系。通过构建面板VAR模型度量了宏观经济与金融变量对银行稳定性的冲击。方差分解的结果显示,银行稳健性的波动主要受自身和GDP的影响,GDP增长率对BSI的波动的解释程度接近50%,说明银行的稳健性依赖于稳定的经济增长,受经济冲击的影响程度相当高。     

智力资本与企业战略绩效:基于中国上市公司的实证研究

基于企业资源观的分析框架,从促进企业竞争优势的稀缺战略资源特性出发,构建了智力资本贡献于企业战略绩效的关系模型。采用上市公司2006-2008年的相关数据,对智力资本与企业战略绩效之间的相关性进行了实证研究。研究结果显示物质资本与企业战略绩效显著正相关,人力资本对企业具有积极的价值创造作用,结构资本与企业战略绩效呈一定程度的正相关关系。     

产业结构调整下的交通运输业发展研究

为了揭示产业结构与交通运输结构间的联系,本文利用河北省公布的2013年统计年鉴相关数据,运用灰色关联度理论,计算第一、二、三产业与交通运输间的灰色关联度。结果表明:河北省第二产业的发展与铁路运输密切相关,第三产业的发展与铁路和公路关系密切。     

中国对外直接投资促进抑或抑制了企业出口？

2001年以来中国对外直接投资实现了持续快速的增长,本文旨在考察对外直接投资究竟对企业出口产生了怎样的影响。利用高度细化的工业企业数据库和海关贸易数据库首次从微观层面进行系统的研究,结果表明,对外直接投资不仅显著地提高了企业出口占销售的比例,而且还提高了企业出口的概率。此外,通过引入生存分析模型的研究表明,对外直接投资显著降低了企业退出出口市场的风险率,即倾向于延长企业出口持续期。本文从微观层面证实了中国企业对外直接投资具有显著的出口创造效应,这一核心结论在剔除贸易中间商、排除加工贸易、剔除投资于避税港的企业以及采用最近邻匹配样本进行估计时都非常稳健。     

基于DEA方法的云南旅游业效率研究

Assessing the efficiency of switchgrass different cultural practices for pellet production

Switchgrass is a perennial crop producing high amounts of biomass for good quality pellet production. The objective of this study is to examine the efficiency of different cultural practices of switchgrass for pellet production under field conditions for four different N-fertilization (0, 80, 160 and 240 kg ha⁻¹) and two different irrigation levels (0 and 250 mm), in two soils in central Greece with rather different moisture status over the period 2009–2012. Moreover, comparison between three harvest methods (two different types of bales and silage) was made. The results derived from this study revealed that the bale at 22 kg is the harvesting practice with the highest costs while there was reduction of efficiency scores when nitrogen levels increased. At both environments the efficiency scores followed the same trend, confirming that low levels of nitrogen fertilization enhance the economic competitiveness of switchgrass production. Palamas site is the area where switchgrass for pellet production had positive income ranging from 400 to 1600 € ha⁻¹, while Velestino site had always negative. Therefore, places like Velestino with non-aquic soil should be avoided for switchgrass. These data suggest that growing switchgrass for solid biofuel production as energy crop is a worthwhile decision only in areas with a moderately shallow groundwater table (aquic soil) or maybe in high precipitation regions.     

高层建筑施工安全管理评价研究

随着经济、社会的不断发展，高层建筑越来越多，同时高层建筑施工引发的安全事故也愈发受到关注。文章结合主成分分析及BP神经网络，建立了高层建筑施工安全管理的评价模型，并赋予各指标动态的权重来衡量各项管理措施的重要程度。研究表明，该方法具有一定的客观性和有效性，有利于促进高层建筑施工安全管理目标的实现。     

New cross-proposal entrepreneurship and innovation in educational programs in third level (tertiary) education

Capitalism has promoted and requires the growing knowledge of entrepreneurs, creative people who have the ability to solve problems in the form of innovation. The types of enterprises they create can be social, public and private. By creating an enterprising company new products and new production methods can be introduced, new markets are open, new sources of raw materials and inputs are developed and new market structures in an industry are created. Entrepreneurship can be taught, the question is how to do it. Teaching entrepreneurship should go beyond the business plan. It proposes a form that overcomes the mistakes found by the author in two research studies in 2008 and 2014 in the programs of management in Bogotá.
