Efficiency in wine grape production: comparing long-established and newly developed regions of South Africa.

摘要: Efficiency, partly based on technology, is central to international competitiveness. This article applies a stochastic frontier inefficiency model panel of 77 wine grape farms in South Africa between 2005 and 2015 allows the comparison efficiency levels for old established regions with those newer entrants. Thus, we investigate whether experience plus first choice location matters more than follower's advantage technology. In all regions, greater share permanent labor increased supervision raised efficiency, while inorganic fertilizer less irrigation has opposite effect. Innovations trellising had insignificant effects (except regions) but not replacing vines reduced efficiency. However, higher proportion red varietals also lowered due fall price as these farmers continued concentrate quality reds. The new compensated falling prices by increasing crop size extending area planted, concern quality. appears be successful terms, demand increases it may poor long-term strategy.
