The effect of subsidies on the performance of farms has received a great deal of attention in the literature, although results are inconclusive. Furthermore, much of the related literature examines the effect of subsidies only on technical efficiency (TE). We examine the effect of different types of subsidies on the different components of total factor productivity (TFP) in Slovenian agriculture over the period 2006–2013. We first estimate a Random Parameter Stochastic production frontier model. Then, based on the estimates of this model, we calculate and decompose the TFP index into TE, scale efficiency and technological change. Third, we apply combined difference‐in‐difference and a matching estimator to examine the effect of investment, less favoured area (LFA) and agri‐environmental (AE) subsidies on the different components of TFP. In our case, these subsidies are found to have no significant effect on either TFP or on its components.

投资,LFA和农业环境补贴对全要素生产率构成要素的影响:以斯洛文尼亚农场为例

尽管结果尚无定论,但补贴对农场经营绩效的影响已在文献中引起了广泛关注。此外,许多相关文献仅考察补贴对技术效率(TE)的影响。我们研究了斯洛文尼亚农业在2006–2013年期间不同类型的补贴对全要素生产率(TFP)不同组成部分的影响。我们首先估计一个随机参数随机生产前沿模型。然后,基于该模型的估计,我们将TFP指数计算并分解为TE,规模效率和技术变革。第三,我们采用差异差异和匹配估计量的组合来检验投资,TFP的优惠区和农业环境补贴对TFP不同组成部分的影响。
