摘要:

生产要素离农加剧经济系统性风险,农业支持政策能够促进城乡融合发展。文章基于城乡要素禀赋差异与融合流通机制,构建城乡融合DSGE模型,分析要素短缺和农业支持政策对农业与经济总体的冲击效应。研究发现:(1)劳动供给减少会抑制就业和消费,提升生产成本和通胀水平,投资刺激不显著,农业部门与经济总体波动趋势一致,前者波动幅度更大、时间更长。(2)耕地供给减少会加速劳动力非农化,提升农业生产成本,短期内抑制农业发展,总就业和产出增加,工资降低,农业投资增加,通胀加剧,挤出居民消费,经济总体波动一致,但幅度更大。(3)农业生产性补贴会改进要素配置结构,提升配置效率,促进经济增长,农业生产性财政支出会正向影响经济基本面,对农业和经济总体的冲击效应一致;农业技术创新补贴会加速劳动力离农,激发劳动活力,对农业和经济总体产生积极影响,后者波动幅度较大和持续时间较长。因此,要素禀赋短缺将提高生产成本,加剧经济系统性波动;农业支持政策能够提升要素配置效率,促进农业发展,对经济系统产生积极溢出效应。

Abstract:

The diversification of production factors from agriculture intensifies the risk of the economic system, and the policy of agricultural support and protection can promote the integrated development of urban and rural areas. Based on the difference of urban and rural factor endowment and the integrated circulation mechanism, a DSGE model of urban and rural integration is constructed to analyze the impact effect of factor shortage and agricultural support policies on agriculture, as well as the spillover effect of economic system. The findings are as follows: (1) the reduction of labor supply will restrain employment and consumption, increase production cost and inflation level, investment stimulus effect is not significant, and the agricultural sector is consistent with the overall fluctuation trend of the economy, the former fluctuation range is larger and the duration is longer. (2) The reduction of arable land supply will accelerate the non-agricultural labor force, increase agricultural production costs, inhibit agricultural development in the short term, increase total employment and output, and reduce wages; Crowding out household consumption, stimulating agricultural investment, and exacerbating inflation are consistent with the overall fluctuation of the economy, which is more volatile. (3) Agricultural production subsidies improve factor allocation efficiency and promote economic growth by improving factor allocation structure. Fiscal expenditure on agricultural production has a positive impact on economic fundamentals and has the same impact on the agricultural sector and the overall economy; Agricultural technological innovation subsidies accelerate labor leaving agriculture, stimulate labor vitality, and have a positive impact on agriculture and the economy as a whole, the latter has a strong fluctuation range and duration. The shortage of factor endowments will restrain employment and consumption markets, raise production costs, and exacerbate systemic economic fluctuations. Agricultural support and protection policies can improve the efficiency of factor allocation, promote agricultural development, achieve “grain storage and technology”, and produce positive spillover effects on the economic system.

Key words: factor shortage, productivity subsidies, DSGE model, model evaluation
