中文摘要:
      农业机械化与完善的农业风险管理是现代农业发展的重要标志,也是实施乡村振兴战略的重要内容。基于效用最大化理论和前景理论,利用广西适度规模经营水稻农户的调查数据,采用联立方程模型和三阶段最小二乘法(3SLS)估计方法,分析生产风险、风险规避对农户生产机械投资的影响,探讨其作用机制,并从农户投资购买机械与购买机械服务两个方面解析农户生产机械投资的风险管理效应。结果表明,洪涝、干旱、台风和市场风险是广西水稻生产过程中的主要风险,农业机械是农户应对风险的主要措施。农户对投资购买机械相比购买机械服务具有更强的风险管理效应认知,农业生产风险与农户的风险规避态度促进了农户投资购买生产机械,抑制了农户对第三方农业机械服务的采用。但这种影响在不同经营规模农户中存在一定差异,生产风险对较大规模农户投资购买机械影响更强,风险规避则对中小规模农户的影响更大。另外,土地规模连片、农民专业合作组织、农业劳动力工资等也对农户投资购买机械或购买机械服务存在显著影响。据此,提出鼓励并支持适度规模经营农户的生产机械投资、引导小农户科学投资农业生产机械、建立全面农业风险管理等政策建议。
英文摘要:
      Agricultural mechanization and appropriate agricultural risk management are important features of the development of modern agriculture and are also important components of rural vitalization. Based on the rational choice theory and prospect theory, this paper examines how farmers’ production risks and risk attitude affect their production machinery investment using a representative rural household survey data from Guangxi. Simultaneous equation model and three-stage least squares (3SLS) estimation are employed to empirically test the hypothesized mechanism, and analyze the risk management effect of machinery investment as captured by machinery and service purchases. Results show that that floods, droughts, typhoons and market risks are the main risks for rice production in Guangxi, and agricultural machinery usage is the main strategy for farmers to cope with production risks. Farmers have a stronger perception that machinery purchase is a better choice than buying machinery services. Production risks and risk aversion have significantly promoted farmers’ investment in production machinery and inhibited their adoption of agricultural machinery services. But the impacts of risk and risk aversion differ among farms of different production scales. Production risk has a stronger impact on large-scale farms to purchase machinery, and risk aversion has a greater impact on small and medium-sized farms. At the same time, the land connectivity, cooperative organizations, and rising farm wage also have significant impacts on farmers’ machinery purchasing or services purchasing. Our findings highlight the importance and necessity of encouraging and supporting farmers’ investment in production machinery to guide farmers to scientifically invest in agricultural machinery and to establish a comprehensive risk management system.
