资源富集区资源开发、生态环境与经济发展耦合协调的空间分异特征研究--以广西桂西资源富集区为例

资源开发是资源富集区经济建设的重要依托。在保护生态环境的前提下,充分发挥优势资源的价值以带动经济的发展,是该地区实现可持续发展的重大课题。以资源富集典型区-广西桂西资源富集区为研究对象,采用主成分分析法并构建耦合协调度模型,对2011年桂西资源富集区30个县（市、区）的资源开发、生态环境与经济发展的耦合协调情况进行了测度和评价,并分析其空间差异特征。结果表明：（1）桂西资源富集区资源、生态、经济耦合协调的空间分异显著,协调发展水平最高的是右江区,最低的是乐业县,两者协调发展度的分值极差达1.8327;（2）协调发展水平总体呈现中部高于北部和南部,市区好于县域地区,区域内部分布特征各异的空间格局。     

从金融视角审视中国传统农地产权及地权交易

明清以来,我国农地具有明确的产权制度,独立而多层次的产权,复杂多样的产权交易形式,促进了土地的流动,这为农户根据自身状况合理配置劳动、土地和资本打下了基础,促进了资源的有效配置。从金融视角审视我国明清的土地市场其实是一个集债券市场、股票市场、衍生品市场和信贷市场在内的复杂的金融市场,但由于历史的局限没有发展成为真正意义上的金融市场,其中因素还有待研究。同时,历史上出现过的衣地产权制度和交易形式为我们当今的土地改革提供了重要的借鉴意义。     

The future of agriculture and society in Iowa: four scenarios

Iowa is a leader in crop and livestock production, but its high productivity has had concomitant negative environmental and societal impacts and large requirements for fossil-fuel-derived inputs. Maintaining agricultural productivity, economic prosperity and environmental integrity will become ever more challenging as the global demand for agricultural products increases and the resources needed become increasingly limited. Here we present four scenarios for Iowa in 2100, based on combinations of differing goals for the economy and differing energy availability. In scenarios focused on high material throughput, environmental degradation and social unrest will increase. In scenarios with a focus on human and environmental welfare, environmental damage will be ameliorated and societal happiness will increase. Movement towards a society focused on human and environmental welfare will require changes in the goals of the economy, whereas no major changes will be needed to maintain focus on high throughput. When energy sources are readily available and inexpensive, the goals of the economy will be more easily met, whereas energy limitations will restrict the options available to agriculture and society. Our scenarios can be used as tools to inform people about choices that must be made to reach more desirable futures for Iowa and similar agricultural regions.     

Loan availability and investment: can innovative companies better cope with loan denials?

This study examines the consequences of loan denials for the investment performance of small- and medium-sized German enterprises. As a consequence of a loan denial, innovative companies experience a smaller drop in the share of actual to planned investment than noninnovative companies. The nonrandomness of loan denials is controlled for with a selection equation employing the intensity of banking competition at the district level as an exclusion restriction. We can explain the better performance of innovative companies by their ability to increase the use of external equity financing, such as venture capital or mezzanine capital, when facing a loan denial.     

THE RELATIONSHIP BETWEEN PURCHASING AND SUPPLY MANAGEMENT'S PERCEIVED VALUE AND PARTICIPATION IN STRATEGIC SUPPLIER COST MANAGEMENT ACTIVITIES

As firms have placed more emphasis on their core competencies and outsourced production and services to suppliers, effective cost management of purchases has become a critical factor in achieving corporate success. The Purchasing and Supply Management (PSM) function is generally responsible for obtaining goods and services from outside suppliers. Techniques such as total cost of ownership, supplier cost structure analysis, and target costing have become important tools for PSM to manage inbound supply costs. Results of a survey indicate that the perceptions of PSM by peer functions and top management, in terms of PSM's importance and accountability, are related to implementing the strategic cost management activities of total cost of ownership, supplier cost structure analysis, and target costing.     

资源利用问题中增加固定目标值的改进技术方法

本文针对资源利用问题的线性规划模型进行理论分析,通过建立改进技术条件即改变变量系数向量的方法,达到增加固定目标函数值的目的。列举算例验证方法的正确性及可行性;伴随固定目标函数值的不断增加,规划模型总是有解,这表明经济效益的目标总可以通过技术进步来实现,并且是没有穷尽的;文章还着重揭示模型内其他方面的经济含义。     

公共财政资源配置职能的实现机制

国内外有关公共财政职能的文献可谓汗牛充栋 ,而最为经典的是著名财政学家马斯格雷夫所作的分类。本文认同这种分类方法 ,但是得出这一分析结论的角度却有所不同。本文是从经济学的基本问题和经济学的基本分析方法入手阐述公共财政职能 ,并据此进一步分析公共财政资源配置职能的实现机制。     

自然资源的价值管理:理论、实践与创新

可持续发展最大的障碍即为自然资源瓶颈,如何推动自然资源的可持续利用,推动自然资源使用效率的提高,值得思考.笔者提出,应当以资源价值补偿理论创新自然资源的价值管理模式和管理手段,应当实现自然资源价值的宏观补偿和微观补偿衔接与一体化,以真正实现自然资源的以价值管理为核心的资产化管理.     

资源、资源关系与企业绩效

在分析企业资源的分类及其相互关系的基础上,讨论了企业资源结构与企业短期绩效、长期绩效之间的关系.认为企业短期静态绩效取决于有形资源和无形资源的利用,长期动态绩效取决于企业的资源结构.能力虽然是企业长期绩效的核心根源,但能力必须与企业其他资源相互匹配,才能够促进资源的相互转化,才能获得持续竞争和动态绩效.
