城镇化水平与农民收入的相关性研究

城镇化水平与农民人均收入存在着密切关系，即城镇化水平越高，农民人均收入越高；城镇化水平越低，农民人均收入越低。因此，要增加农民人均收入，就必须提高城镇化水平，特别是提高中西部省份的城镇化水平。文章主要运用统计学中的回归分析方法来阐述这一观点。     

乡镇财政困难：现状、原因、出路——以安徽省为例

乡镇财政困难主要有收入下降、支出膨胀以及债务负担沉重等方面的表，就其原因从其关联性有根本原因、主要原因、重要原因、直接原因以及导火索等五个方面。对此，笔者认为解决乡镇财政困难的出路可以在分析原因的基础上，结合其表现来具体分析。     

Discussion and Analysis about Duration Method Based on Marginal Analysis

The selective principle of mutually exclusive project is the maximum of net present value, It is difficult to make decision when NPVA is equal to NPVLB. Some assistant analyses are put forward in ＂Enterprise Investment Decision Management＂. The scientific marginal analysis shows that the assistant analyses including the duration analysis are wrong. This problem can be solved by the classical marginal analysis.

Dynamics of Child Malnutrition in Rural and Small‐Town Ethiopia

Improving the status of malnourished children, and preventing children from becoming malnourished, lies at the heart of several of the Sustainable Development Goals. While many cross‐sectional studies examine correlates of stunting, they largely cannot identify drivers of change in stunting. We use two waves of panel data from Ethiopia and incrementally larger sets of fixed effects to control for time‐variant observable characteristics and time‐invariant unobservable characteristics. After controlling for these potential confounders, our analysis reveals that many factors that are associated with stunting in the cross‐section do not impact stunting dynamics. We also estimate individual fixed‐effects regressions, separately, according to baseline stunting status. We find evidence suggesting that while improved societal conditions drive many children out of a stunted state, certain exogenous factors may lead previously healthy children to become stunted. Overall, policymakers and practitioners would be wise to consult research utilising both cross‐sectional and panel data analyses in order to more effectively target already stunted children as well as vulnerable children who may be at risk of becoming stunted.     

基于占补平衡政策的土地整治项目成本分析及发展趋势——以陕北榆林地区为例

从国家占补平衡政策变化入手,以陕北榆林地区土地开发项目为例,通过近年来土地整治项目设计标准,人工、材料费用及当地市场环境变化等几方面,分析影响土地整治项目施工成本的因素,得到土地整治项目成本呈增加趋势,且主要因素为：①平整度、林网等设计标准的提高;②柴油、钢材等主材价格的浮动;③税率的调整;④项目本身、社会条件及环境的影响。并在此基础上,简要分析了土地整治项目发展趋势。
