2004—2014年间,珠三角经济增长速度由快到缓。为考察期间生产要素对珠三角9市经济发展的影响,提高要素生产效率和促进区域经济产业优化,本文通过构造相关空间影响因素,并将其引入到SEM空间计量模型研究和测算区域生产要素效率,了解其对经济的促进作用。发现引入空间相关能够显著提高模型精度,珠三角区域经济生产率的提高主要依赖资本投入和劳动力投入,科技投入的作用相对较低。最后根据珠三角城市之间的经济联系,有针对性地提出区域经济发展的对策和建议。
During the period of 2004-2014, the economic growth in the Pearl River Delta accelerated to a slower pace. In order to investigate the influence of factors of production on the economic development of nine cities in the Pearl River Delta, improve the efficiency of factor production and promote the optimization of regional economy and industry, this paper constructs the relevant spatial influencing factors and introduces them into the study of SEM spatial econometric model and the calculation of the regional factors of production efficiency , Understand its role in promoting the economy. It is found that the introduction of spatial correlation can significantly improve the accuracy of the model. The improvement of economic productivity in the PRD region mainly depends on capital input and labor input, and the contribution of S & T input is relatively low. Finally, based on the economic relations among the cities in the Pearl River Delta, the countermeasures and suggestions for the development of regional economy are put forward in a targeted manner.
