通过对江苏省农村中小企业的实地抽样调查,首先运用DEA方法测算了样本农村中小企业的技术效率、纯技术效率和规模效率,进而运用Tobit模型分析了信贷可获性对样本企业技术效率的影响。研究结果表明:农村中小企业的技术效率偏低,其主要原因是纯技术效率过低;农村中小企业仍然存在一定的融资约束,且信贷可获性对企业技术效率有着显著的正向影响;实证结果进一步发现,企业年龄、原材料成本、资产投入、职工投入、研发人员比重、资产负债率等也是影响农村中小企业技术效率的主要因素。
Through the field survey of rural SMEs in Jiangsu Province, the technical efficiency, pure technical efficiency and economies of scale of the sample rural SMEs are first estimated by using the DEA method. Then Tobit model is used to analyze the impact of credit availability on the technical efficiency of the sample enterprises . The results show that: the technical efficiency of rural SMEs is low, the main reason is the low efficiency of pure technology; the rural SMEs still have some financing constraints, and credit availability has a significant positive impact on the technical efficiency of enterprises; The results further found that the age, raw material costs, capital investment, staff input, R & D personnel, debt ratio and other factors are also the main factors that affect the technical efficiency of rural SMEs.
