中国产业税收政策有效性研究——基于模糊综合评价模型

在构建产业税收政策有效性评价的层次结构指标的基础上,通过模糊综合评价模型对中国产业税收政策有效性进行实证研究。结果发现,产业税收政策对经济的适应性不强、与其他经济政策的协调性较差等因素制约了中国产业税收政策作用的有效发挥。因此,准确定位财税政策的作用领域、优化产业税收政策运行的环境、构建适应产业结构升级的财税体系,是提高产业税收政策有效性的关键。     

国有林场改革成效评价——职工获得感的统计分析

利用国有林场职工监测数据,基于物质维度和精神维度,从改革后职工自身的收益情况、职工对林场的整体评价、职工对林场管理方式的评价等方面,采用比较分析法和主成分分析法对国有林场改革职工获得感进行分析。研究结果表明:国有林场改革后职工获得感有所提升,改革进程与职工获得感呈强正相关性,改革促进了林场的可持续发展。但林场整体基础设施环境一般,场部相对较好,管护站点则较差。同时,在领导班子建设方面应注重自主、公平,仍需提高领导水平。     

Assessing cost‐effectiveness when environmental benefits are bundled: agricultural water management in Great Barrier Reef catchments

Using economic analysis to prioritise improvements in environmental conditions is particularly difficult when multiple benefits are involved. This includes ‘bundling’ issues in agricultural pollution management, where a change in management action or farming systems generates multiple improvements, such as reductions in more than one pollutant. In this study, we conceptualise and compare two different approaches to analysing cost‐effectiveness when varying bundles of benefits are generated for a single project investment. Each approach requires data to be transformed in some way to allow the analysis to proceed. The index approach requires the transformation on the benefits side so that the effects of multiple pollutant changes can be combined into a measure for each project which can then be compared to costs. By comparison, the disaggregation approach requires the transformation on the costs side where costs for each project have to be apportioned across the different pollutants involved. The paper provides novel insights with an application to agricultural water quality improvements into the Great Barrier Reef in Australia, demonstrating that while both approaches are effective in prioritising projects by cost‐effectiveness, the disaggregation approach provides more insightful results and values that may be relevant for use as upper value guidelines in future project selection.     

The effects of social TV on television advertising effectiveness

Social TV is the use of communication devices to connect with family and friends watching other TV screens. Plausible arguments suggest both positive and negative effects of social TV viewing on ad-effectiveness. This study contributes by providing evidence for the direction of social TV's effects. The results of a controlled laboratory experiment suggest that the benefits of social TV, principally its association with live TV and therefore less ad-avoidance, come at the cost of negative distraction effects. Like normal coviewing, social TV viewing distracts from ad-processing, reducing unaided recall and brand attitude favorability, compared to individual (solus) viewing. However, social TV messaging about ads improved brand attitude. Perceived creativity increased the likelihood of ad-related messaging. Social TV also has an additional source of distraction, multitasking, but in this study, multitasking did not further reduce ad-effectiveness compared to coviewing. The paper concludes with implications for advertisers and future research.     

Cost-Effective Targeting of Land Retirement to Improve Water Quality with Endogenous Sediment Deposition Coefficients

An integrated framework that combines spatial and biophysical attributes of land with a hydrological model and an economic model is developed to identify cropland for enrollment in the Conservation Reserve Enhancement Program. Sediment deposition coefficients are determined endogenously depending on the land-use decisions on other land parcels. Application of this framework to a watershed in Illinois demonstrates that highly sloping land adjacent to water bodies should be selected for retirement. A marginal value rental payment scheme can achieve program goals of 20% sediment abatement at 39% lower cost than a productivity-based rental scheme.     

增长极战略的实现机制与中国实践模式的重构

增长极理论是20世纪50年代新古典区域均衡发展理论遭遇危机之后的新选择,但自其诞生以来由于缺乏成功案例的支持而备受争议。我国区域非均质、不平衡使得增长极模式备受推崇,但在发展中同样遭遇困境。鉴于理论与现实鲜明的反差,以增长极的实现机制为切入点剖析了该理论的不足,指出我国三大增长极在实践中存在政府依赖刚性、自我发展能力弱、关联效应差等问题,认为完整的增长极实现机制应包括形成机制、运行机制和扩散机制,并从这三大机制入手重构了中国增长极的实践模式,提出相关政策建议。     

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。

我国货币政策的实效分析

本文运用希克斯－汉森模型作为基本分析工具,采用实证计量分析手段,对我国改革 开放以来的ＭＰＣ、ＭＰＳ及居民实物储蓄、货币储蓄和金融储蓄数据进行分析,将其纳入希克斯 －汉森模型,作出ＩＳ曲线陡峭, ＬＭ曲线平缓的现实模拟模型,由此分析得出我国近几年来货 币政策尤其是自１９９８年以来货币政策效果微弱的结论 。笔者列举了货币政策微弱的原因：没有 一个足以发挥政策的场地,资本市场非市场化,各行为人不能平等进入资本市场,从而导致利 率扭曲和贷款不真实,及Ｓ不能及时转化为Ｉ,造成严重的投资需求不足。解决的办法是：短 期内,加大投资,将Ｓ转化为Ⅰ,它将比刺激消费更有效。长期内,将资本推向市场,使货币 政策真正发挥作用。     

基于SSP范式的环境影响评价有效性研究

引入美国密歇根州立大学教授阿兰·斯密德开创的状态-结构-绩效(SSP)范式来分析我国环境影响评价制度的执行绩效.通过对该制度成本和收益的比较得出:环境影响评价制度的设计所带来的绩效更倾向于占社会总体一少部分的政府与建设单位,占社会总体绝大多数的公众的环境权益得到的是形式的而非实质的保证,最终导致制度设计与制度目标的背离.
