基于RC-AHP模型的肉鸡产业“公司+农户”契约稳定性的评价研究

契约稳定对于"公司+农户"的经营模式具有重要的意义,而契约稳定的评价模型是衡量契约稳定的重要工具。本文以山东省五家肉鸡加工企业为例,基于RC-AHP方法构建契约稳定评价模型进行评价和分析。研究表明,资产专用性对契约稳定影响较大,交易不确定性和交易频率对契约稳定性的影响相对较小。同时,交易周期、市场价格的不确定性和物质资产专用性对契约稳定性也有重要的影响。

NOMINAL GDP TARGETING AND CENTRAL BANK CONSERVATIVENESS

In the literature on monetary economics, there is the ‘inflationary bias’ result which predicts that the rate of inflation will be biased towards a higher level under discretionary monetary policy than under a rule‐based policy regime. It is established that a credible nominal target can eliminate this ‘inflationary bias’. In this paper, we examine the case of nominal GDP targeting, which is a rule‐based monetary regime. Depending on the degree of conservativeness by the central bank, we show in a stylized model the choice of different combination of inflation and real GDP targets can still result in an ‘inflationary bias’, and there also exists the possibility of a ‘dis‐inflationary bias’.     

Is China’s Manufacturing Industry Efficient? Evidence from an Energy-Rebound Effect Perspective

Majority of the increase in global energy consumption is from China; hence, studying energy issues, especially in China’s manufacturing industry (CMI), is worthwhile and of much interest in the academic field. Based on the translog cost function, we develop a research framework to study the rebound effect of CMI. Considering the effect of asymmetric energy price, we augment the energy-cost function with asymmetric influence constraint of energy price. Again, we add time series data of CMI’s capital, labor, energy, and mid-input to the model to calculate the direct rebound effect of CMI. We find that the rebound effect of CMI is 44.2%, and CMI still has large energy-conservation potentials. Based on the results of this study, some policy recommendations are provided.

汽车类院校一体化教师培养模式的研究

随着我国社会主义市场经济和职业教育的迅速发展,社会及企业要求学校毕业生要有一定的理论知识又要有很强的实际操作能力。新的人才需求要求有新的教学模式——"专业基础理论与技能实践一体化"教学模式,要成功地实施一体化教学模式,建设一支既能胜任理论教学又能指导实习操作的"双师型"教师队伍是实施一体化教学的关键。本文就汽车类院校一体化教师培养模式进行探索。     

基于多维频谱地图的干扰规避

针对复杂电磁环境下卫星移动通信系统可靠通信需求，利用频谱地图多维数据呈现优势，提出了基于多维频谱地图的干扰规避方法。通过建立卫星移动通信系统波束、时隙、子频带、干扰强度等多维信息关联的频谱地图，利用数据挖掘方法对频谱可用情况进行预测，基于预测结果及用户QoS(Quality of Service)需求生成干扰规避策略，通过星地联合频谱资源调配实现系统干扰规避。该方法为卫星移动通信系统干扰规避提供了一种全新的思路，可提升卫星移动通信系统干扰防护能力。
