过去40年,中国经历了快速的农村转型。与快速转型相伴而生的是农民家庭收入的显著增加和农村贫困人口的大幅减少。本文基于省级数据考察了农村转型(高值农业和农村非农就业)及其效果(农民人均收入和农村贫困发生率)的演变与关系。结果表明:各省都发生了显著的农村转型,但转型的水平和速度存在较大差异。此外,农村转型水平越高的省,农民收入越高、农村贫困发生率越低。需要说明的是,本文也根据高值农业和农村非农就业分析了省际农村转型的类型。本文还进一步讨论了制度、政策和投资(IPIs)对农村转型的潜在影响并总结了政策启示。

Given the sudden outbreak of the COVID-19 pandemic, a timely study on the impacts of and policy response to the pandemic on rural poverty in China is critically important because China has aimed to completely eradicate extreme poverty by the end of 2020.  This paper uses data from the latest round of a nationally representative household panel survey to examine the impacts of the pandemic on rural poverty in China.  Our data show that 11.9% of sample households were ever officially registered as poor households between 2013 and 2019, and this poverty incidence fell to 2.7% by the end of 2019.  In the middle February of 2020, 23% of the households who have graduated from poverty since 2013 perceived that they would fall back into poverty due to the COVID-19.  Among those never poor households, 7.1% perceived that they would possibly fall into poverty due to the pandemic.  Results from both descriptive and multivariate analyses consistently show the interruptions that the pandemic caused in off-farm employment is an important channel that led households to perceive of falling back into or falling into poverty.  We also find households in the bottom four quintiles when ranked in terms of household income per capita are much more likely to perceive themselves of falling back into or falling into poverty during this pandemic than those in the richest quintile.  Meanwhile, our results show that the education and age of household heads, as well as being from Hubei Province matter in explaining household perception about falling back into or falling into poverty in some cases but not all.  The paper concludes with a set of policy responses that China has taken to mitigate the impact of COVID-19 pandemic on poverty alleviation.

Biomass yields and concentrations of crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), acid detergent fiber (ADF), and crude fiber (CF) were analyzed for five cultivars of summer-sown maize (Zea mays L.) stover grown in field trials at three rates of N fertilization, and sampled immediately after grain harvest. The results revealed differences in yields and concentrations of nutrients according to stalk height and hence harvest portion among the cultivars. N application greatly increased biomass yield and CP, especially in upper stalks and to a lesser extent, EE. Concentrations of NDF and ADF decreased as N rate increased. The results show that stovers from all local popular maize cultivars are suitable as animal fodder and that moderate N application improves feed quality of stover.
