基于DEA-Malmquist指数模型的泛娱乐企业经营效率评价

Evaluation of Business Efficiency of Pan-Entertainment Enterprises Based on DEA-Malmquist Index Model

文章基于DEA模型与Malmquist指数从静态与动态两方面对我国12家泛娱乐上市公司经营效率进行评价。研究结果表明:规模的大小对泛娱乐企业效率的提升有着重要的作用,但多数泛娱乐企业的规模投入与产出不成正比,而目前大部分泛娱乐企业在核心技术上还有很大进步空间,同样需要继续努力。因此,泛娱乐企业应将发展技术放在首位,创新投入方式,提高规模效率。

Since the opening to the outside world,China's economy has been growing rapidly,and China's import and export trade has developed greatly,which provides a strong driving force for China's economy.This paper analyzes the influence of Shanghai's import and export trade on economic development since 1978.The results show that import and export trade has a greater contribution to Shanghai's economic growth,and export is more important than import.At the same time,exports have greatly increased the input of Chinese labor,boosting economic growth but depressing investment.Import has a certain squeezing effect on the labor market,but also has a certain negative impact on the labor market.
