中国技术进步贡献率的度量与分解

本文在分析索洛余值法缺陷的基础上,以新增长理论为理论背景,结合中国经济发展的现实,将产业结构变动、资本空间集聚、人力资本积累等因素引入技术进步贡献率的计量模型,使技术进步贡献率的度量更接近真实的技术进步情况;进而利用新的技术进步贡献率计量方法重新测算了1987—2003年间中国的技术进步状况,发现中国技术进步贡献率已开始出现稳步增长的趋势。     

What lies behind the success of Italian GIs products? Questioning tradition in consortia via aggregated conditional efficiency

Firms and territories are considered extremely interrelated, especially approaching the market of agri-food products detaining the PDO (Protected Designation of Origin) and PGI (Protected Geographical Indication) labels. By aiming at reducing costs and simultaneously exploiting potential benefits, entrepreneurial realities often collaborate through consortia. This aspect takes on a crucial relevance when considering the Italian context, widely known for its high-quality products, the vocation to cooperate, and the high adaptability to insidious locations. In this light, this study assesses the efficiency level of in-the-consortia Italian firms by conditioning for two external factors affecting the input–output process evaluated, i.e. physical riskiness and vocation to cooperate. The Data Envelopment Analysis (DEA) scores are aggregated by using firms’ membership in the consortia as the DEA aggregation criterion. More than 600 firms aggregated in 50 consortia allow for a capillary and locally-based study over the 2011–2020 period. The study signals tips about geographical concentration and proximity since it tests whether tradition and attitude to cooperate motivate the agri-food industry efficiency level, in line with the historical regional background of these organizational forms. Finally, suggestions to exploit the market of certified products are discussed both for policy-makers and practitioners, as well as new opportunities for future research.
