Purpose-This research aims to estimate the technical efficiency of Chinese table grape wholesalers and subsequently to examine the degree to which the calculated efficiency correlates with a set of explanatory variables. Design/methodology/approach-A two-stage procedure is applied in this paper. First, a non-parametric data envelopment analysis (DEA) technique is applied to investigate the degree of technical efficiency for Chinese table grape wholesalers. Secondly, Tobit regression is used to analyze the factors influencing technical efficiency. Findings-Research results reveal that the mean technical efficiency of the sample is 0.544 and 0.860 under CRS and VRS assumptions, respectively, and the scale efficiency is 0.620. The variables of experiences, number of grape varieties on sale, daily selling volumes and fixed sale ratio have a significant effect on technical efficiency, whilst the other exogenous variables do not affect the efficiency in any significant way. Research limitations/implications-The findings of this research are specific to table grape wholesalers in China, however, the method used in this study is transferrable and applicable to the study of similar problems in others countries. Originality/value-This research has yielded some interesting and original insights into the efficiency level of Chinese grape wholesalers and the factors that influence the level of efficiency. The findings have practical implications for Chinese agriculture policy makers, and are able to stimulate further research of a similar type in the international agricultural research community.
Purpose -Table grape is one of the most important horticultural crops in China. However, quality and safety have become major constraints for the further development of the Chinese table grape industry, which is dominated by small-scale vinegrowers. Strategic partnership has been regarded as an effective mechanism to manage the supply chain. The purpose of this paper is to examine the impact of a supply chain model based on different strategic partnerships on the effect of safety and quality control and small-scale vinegrowers' performance. Design/methodology/approach -The field survey was performed in seven representative districts in China, including Inner Mongolia, Gansu, Tianjin, Liaoning, Shandong, Jiangsu and Zhejiang Provinces. A semi-structured interview was adopted as the data collection method. Both quantitative and qualitative data were generated and analyzed in this research. All quantitative analyses were conducted using EXCEL 2003 version and a comparative analysis was conducted to test the hypotheses. Findings -The results show that modern supply chains are more efficient than the traditional one in improving the effect of safety and quality control and small-scale vinegrowers' performance. Originality/value -This paper first identified different models of table grape supply chain based on different strategic partnerships, and then analyzed the impact of supply chain model on the effect of quality and safety control and small-scale vinegrowers' performance. It concludes with some policy suggestions relative to further development of the table grape industry in China.
