【摘要】本文运用DEA-Tobit两阶段法,在测度2004~2008年中国玉米全要素生产率的基础上,进一步探究了粮食综合性收入补贴对玉米全要素生产率的影响。研究表明:2004~2008年期间,中国玉米全要素生产率有所提高,这主要是技术进步作用的结果;西部地区玉米全要素生产率提升极为显著,东部和东北地区玉米全要素生产率改善则较为缓慢;综合性收入补贴对提高玉米全要素生产率具有正向影响,农村劳动力人均受教育年限和耕地有效灌溉率也有正向影响,年平均气温和年日照时数则有负向影响,劳均玉米种植面积和亩均耕地农机动力的影响并不显著。从政策操作的角度看,综合性收入补贴与粮食生产有脱钩的趋势;但从实际效果来看,它仍有助于提高粮食全要素生产率,也没有引起市场扭曲和效率损失,因此是一种可选用的补贴方案。

【Abstract】This paper further analyzed the effect of the comprehensive income subsidy for grain on maize TFP with the DEA-Tobit Two-Stage Method and on basis of the measurement of China’s maize TFP during 2004–2008. The study showed that during 2004–2008 China’s TFP rose to some extent because of technological progress; in terms of maize TFP, the western part of China had very significant rises, and the eastern part of China and the northeastern part of China had slow improvement; the comprehensive income subsidy had positive effects on the improvement of TFP, the per-capita educational years of rural laborers, and the rate of effective farmland irrigation also had positive effects; the annual average temperature and annual sunshine duration had negative effects, and the planting area of maize per worker and power of farmland agricultural machinery per mu had insignificant effects. From the perspective of implementing policies, the comprehensive income subsidy and grain production tended to be separated from each other. However, according to the actual effect, as an optional plan for subsidies it could still help to improve TFP of grain without distorting the market and losing efficiency.

    [1]. ① The direct subsidy in its narrow sense means support in the form of subsidies from government finance to agricultural operators according to certain conditions and standards, such as the comprehensive subsidy for agricultural materials, the subsidy for improved seeds, and the subsidy for purchasing agricultural machinery. The direct subsidy in its broad sense also includes support in the form of subsidies from government finance to the entire agricultural sector, and is not targeted to farmers and specific agricultural products, such as input and subsidies in the aspects of constructing agricultural infrastructure, promoting agricultural technology, and protecting agricultural resources and the environment.

    [3]. ② According to the Guidance Book of Decision of the Central Committee of the Communist Party of China on Several Major Issues on Promoting the Reform and Development of Rural Areas, China has established the primary system of agricultural subsidy policies with complementary functions, comprehensive subsidies and special subsidy combined, and categorized DSGF and CDSAPM as the subsidy policies for farmers’ incomes (hereinafter referred to as comprehensive income subsidies) to increase farmers’ income; it has categorized the subsidy for improved seeds and the subsidy for purchasing agricultural machinery as subsidy policies for producing agricultural products (or special subsidies for production) to promote agricultural production (see the editing group of this book, 2008). When policies are implemented, the subsidy for improved seeds paid by cash and CDSAPM can be treated as comprehensive income subsidies for sharing largely the same operational means and effects. In 2016, the Chinese government integrated DSGF, CDSAPM and the subsidy for purchasing agricultural machinery into subsidies for agricultural support and protection, which reflected similarity of the three subsidies. Therefore, comprehensive income subsidies elaborated by this paper include DSGF, CDSAPM and the subsidy for improved seeds of crops. [^Back]

Now, China’s soybeans, seeds of rape and so on have been facing constraints of the ceiling of the Amber Box of special agricultural products. [^Back]

    [17]. ④ At the areas conducting the pilot reform, according to the Suggestions on Adjusting and Improving the Policy of Three Kinds of Agricultural Subsidies promulgated by the Ministry of Finance of the People's Republic of China, DSGF, the subsidy for improved seeds and 80% of CDSAPM are paid by cash to farmers for protecting farmland capability according to the contractual area they have, but the farmers receiving the subsidy should promise not to desert the land and reduce the soil capability (as a Green Box policy); 20% of the CDSAPM, the subsidy for large grain-growing households and Incremental capital of three kinds of subsidies are used to support capacity of grain and promote appropriate-scale operation, including credit guarantees, the subsidy for credit interest and moderate subsidies in the form of cash to entities planting grain above the designed scale (as an Amber Box policy).
