基于DPSIR模型的北京市可持续发展评价

随着城市化进程的不断推进,北京市城市经济快速发展的需求与环境的保护、资源的可持续利用已成为城市发展的主要矛盾,空气污染、水资源紧缺、交通、住房压力大等问题非常突出。面对这种情况,必须坚持科学发展观,努力实现人口、经济、环境和能源等因素的协调发展。结合城市可持续发展的内涵和北京市的城市发展现状,采用驱动力—压力—状态—影响—响应(driving-forces-pressure-state-impact-response,DPSIR)理论框架构建城市可持续发展综合评价指标体系,将熵值法和层次分析法相结合合理确定指标权重。选取了2001—2014年北京市城市发展指标数据,从驱动力、压力、状态、影响、响应等5个方面,对北京市可持续发展水平进行系统评估和分析,识别关键因素和重要环节,并提出建议和措施,为实现和优化北京市经济、社会和环境的可持续发展提供指导和支持。     

内蒙古草原生态补偿意愿的实证研究

草原生态补偿意愿是确定草原生态补偿标准的重要参考,理论上补偿意愿包括补偿主体的支付意愿和补偿对象的受偿意愿。利用条件价值评估法(CVM)研究补偿主体的支付意愿和补偿对象的受偿意愿。通过采用SPSS软件中的皮尔逊相关分析法得出如下结论:内蒙古地区居民对草原生态补偿的支付意愿是23.10元/hm2.年;内蒙古草原牧区牧民的受偿意愿是1 944.75/hm2.年。影响支付意愿的因素主要是被访者的受教育程度(即学历水平)、对草原生态环境的认知程度和家庭人口;影响受偿意愿的因素主要是牲畜饲养方式和牧民居住地距离旗政府所在地的距离。     

审计成本、审计师变更与审计质量——基于重大资产重组的视角

以2007~2012年获得批准进行重大资产重组的公司为核心样本,研究了重大资产重组、审计成本对审计师变更的影响及审计质量的变化。研究发现,处于重组期间的公司和原审计师审计成本较高的重组公司变更审计师的概率更高,公司重组期间的审计质量更低,且审计师变更会加剧审计质量的降低程度;重组公司中审计师变更公司与未变更公司的审计质量无差异,但在审计师变更的公司中,重组公司的审计质量更低。

Areal differentiation of virtual water for agricultural products and its effect on regional agricultural structure adjustment in China： 1995-2007

With a vast territory, the space-time distribution of water resources is uneven in China. There is a great dif ference in natural conditions and farmland management of agricuttural production in different regions. The areal differentiation of agricultural products virtual water is obvious. Comparison with the agricultural products virtual water from 1995 to 2007 in China shows an increase in the first ten vears and a little decrease in recent years. There has been a tendency of increase all the time in Northeast and Northwest. but a decrease after an increase firstly in other regions. The virtual water offood crops is the maximum which accounts for more than 70% in China. and that of vegetables is in a fast growth. The proportion of agricultural products virtual water to the total water resources in each region has a large difference, showing the imbalance of agricultural water in different regions, which accounts for 50%-90% in Northeast, and 125%-185% in North China. Under the guidance of virtual water strategy, based on the differences of resource endowment, each region should adjust agricultural structure, decide production by water, and select water suitable crops. In water-rich region, agricultural produets of high water consumption should be planted appropriately, which will make full use of the abundant local water resources. In water-shortage region the crop production of high water consumption and low efficiency should be depressed, and that of low water consumption and high efficiency should be supported and increased. It will achieve reasonable disposition of water resources, promote ecological restoration and environmental protection, as welt as ensure food security.     

基于链式中介效应的真实型领导对员工创新行为影响研究

基于社会认知理论和价值观理论,考察了真实型领导对员工创新行为的复杂影响机制。以374份企业员工数据为样本,通过层级回归分析和Bootstrap方法进行假设检验,研究结果表明：真实型领导对员工创新行为具有显著正向影响;不确定性规避和创新自我效能感在真实型领导与员工创新行为之间分别发挥部分中介作用,而且发挥了链式中介作用,即真实型领导通过降低不确定性规避程度影响员工的创新自我效能感,进而鼓励了员工的创新。     

泰安市城市土地可持续利用的综合评价

根据可持续发展理论和系统论原理,参照国内外可持续发展评价指标,从资源环境、经济、社会三个方面选择了31个因素为参评因子,建立城市土地可持续利用评价指标体系和评价模式。运用综合指数法和协调度模型,对泰安市城市土地可持续利用进行综合评价。结果表明,1997-2001年,泰安市城市土地利用经历了从初步可持续利用、基本可持续利用到可持续利用的不同阶段,并不断向更高阶段演变,可持续性不断增强。协调度在波动中趋于上升,协调状况较好。     

我国区域经济波动对货币政策效力影响的实证分析

本文研究表明,北部、东部和南部等经济较发达地区与总量经济发展能够保持较高同步性,西北等经济欠发达地区则呈现较强的独立性特征;经济较发达地区与总量经济的关系呈现出在扩张期同步性较强、在紧缩期同步性较差的特点,紧缩期对经济欠发达地区影响更为显著;货币政策在不同地区效力不同,东部地区对利率政策具有较高的敏感性,资金推动仍是全国大部分地区经济发展的主要动力。     

从云南三大产业对GDP的影响看滇印贸易发展

云南地处我国西南边陲,是中印陆运贸易的主要通道.云南应借中印贸易加速发展之势,充分利用自身优势发展地区经济.对外贸易的发展会促进经济增长,调整三大产业结构在直接影响 GDP 的同时,通过对滇印贸易的刺激又间接地影响了 GDP 的增长.本文利用灰色关联评价方法对云南的三大产业与 GDP 的关联度进行了分析,云南应保持和稳定其第一产业,加速发展第二产业,引导和扶持第三产业.     

The investment of human capital of peasant household and the growth of farmers’ income

Based on an analysis of some theories, this paper studies the relationships among rural household investments and their interaction with farmer income increase empirically by the data of 1983-2005.

(2) Although migration investment is useful to the growth of farmer income, education and health investment, its effects is time lagged. (3) Education investment has the biggest effects on the growth of farmer income; besides, it also reduces the cost of migration. However, this reduction is a bit small. Finally, some brief suggestions are put forward based on the analysis.
