新农保能促进农户土地流转吗?——基于CHARLS三期面板数据 总被引:1,自引:1,他引:0
基于2011年、2013年和2015年中国健康与养老追踪调查(CHARLS)数据库,构建了三期具备农村户口且拥有耕地的微观农户 面板数据,采用固定效应模型实证分析我国农村老龄化问题背景下新农保能否促进农户土地流转。研究发现:(1)2015年中国耕地的平均转出率和转入率仅为14%和6%,2011-2015年中国耕地呈现转出率逐年递增、转入率逐年递减的趋势,凸显中国耕地出现集聚现象。(2)中国土地流转行为区域差异性明显,耕地转出率顺序为:东北地区>东部地区>中部地区>西北地区>西南地区;耕地转入率除西北地区较高外(2015年为9%),其余各区均在5%左右。(3)新型农村社会养老保险能够促进60岁以上老年农户的耕地转出。政策启示是:提高农村养老保险水平以弱化土地的养老保障功能,进而促进农村土地流转;完善耕地集聚化背景下的土地管理制度,培育一批具有带头作用的新型农民;发展区域差异化的农村耕地管理政策,首先重点针对土地流转潜力大的地区推行土地流转交易。 相似文献

This paper contains a literature review of the occupational injuries and ill-health in agriculture world-wide and a survey
of the attempts that have been made to estimate the resulting economic and social costs.
Agricultural workers suffer a wide variety of disorders as a result of their occupation. These range from minor (cuts, bruises)
to more severe (deep wounds, fractures), permanent (amputation, spinal cord injury) and fatal injury. Ill-health as a result
of contact with animals, micro-organisms, plant material dusts or chemicals are associated with certain types of agriculture.
There is an underlying but unquantified incidence of pain, stress and injury as a result of ergonomic problems due to poor
working procedures and conditions. Statistics from many countries or regions show that agriculture consistently has one of
the highest accident and injury rates of the industrial sectors.
There are many causes for the work related injury and ill-health in agricultural workers. In developed countries, tractors
and other machinery cause a significant proportion of the accidents and are a major cause of occupational deaths. In less
developed countries, accidents due to hand tools such as hoes, sickles and cutting instruments are most prevalent. Animals
are a significant cause of injury and ill-health in many countries. Debilitating allergic reactions in the respiratory tract
or the skin are caused by exposures to organic dusts, or by contact with allergenic plants in the field respectively. Where
comparative data are available, occupational pesticide poisoning in agriculture is a small proportion (< 1–4%) of the total
work related disorders.
Because of the wide variety of occupational risks to agricultural workers, it is emphasised that if one type of agricultural
practice is replaced by another then the risks from the alternative procedure need to be considered. If, for example, agrochemical
pest control practices are replaced by methods involving the increased use of machinery, draught animals or manual operations,
then an assessment of the resulting risks should be taken into account.
Some of the economic costs of occupational injury and ill-health in agriculture can be quantified directly, such as medical
costs, the cost of rehabilitation and loss of earnings. Other costs are more difficult to estimate such as loss of opportunity
and income foregone for permanent and fatal injury and for the effect on a victim’s family. The estimation of the overall
economic costs to farming communities and national agriculture requires further development. When one agricultural practice
is replaced wholly or partly by another, for example agrochemical pest control by alternative control methods, then it is
necessary to take into account the occupational health costs of the alternative procedure for realistic comparative assessment.
There are a number of issues which require continued or increased attention by the relevant national and international authorities
and by the agricultural industry. These include the improved collection and collation of occupational health statistics, a
better understanding of the extent of ergonomic problems in agriculture, more realistic assessments of the cost of occupational
injury and ill-health and the continued need to reduce occupational health disorders by appropriate training and education
in agricultural practices and the use of agricultural equipment. 相似文献
