为长三角地区以开放促转型、培育经济增长新动力提供依据和参考,本文尝试探究对外直接投资对全要素能源效率的系统性影响.以2005—2014年长三角24个城市为样本,基于模拟退火和NLS法的面板平滑转换模型,以人力资本和技术差距为吸收能力变量,考察OFDI逆向技术溢出对全要素能源效率的影响.结果显示:两者之间具有显著的单一门槛特征,且二者关系随吸收能力高低发生转换.具体来看,随着人力资本的提高,前者对后者的影响由轻微负向逐渐变为正向显著,而当技术差距变小,该影响则由正向不显著逐渐变为正向显著.同时,各样本城市呈现明显区域差异,跨越各自门槛值的样本比例偏低,且人力资本方面仅上海、南京及杭州处于高体制,技术差距方面则未有样本城市进入高体制. |

Abstract: |
It explored the systematic impact of outward foreign direct investment on total factor energy efficiency, in order to provide the basis and reference to promote transformation by opening up and cultivat a new impetus to economic growth for Yangtze river delta region. Taking the panel data of 24 cities in the Yangtze River Delta from 2005 to 2014 as samples, with the PSTR model based on Simulated Annealing and NLS method, it studied the effect of OFDI reverse technology spillover on total factor energy efficiency by using human capital and technology gap as absorptive capacity variables. The results show that there is a significant single threshold characteristic between the two, and the relationship between these two variables changes with the level of absorption capacity. In particular, with the increase of human capital, the influence of the former on the latter gradually changes from slight negative to significant positive. When the technology gap becomes smaller, the effect gradually changes from insignificant positive to significant positive. Also, there are significant regional differences among the cities. The proportion of the cities which across their threshold is small, and only Shanghai, Nanjing and Hangzhou are in the high system from the perspect of human capital. In terms of technology gap, there is no city in the high system. Finally, the suggestions were given. |
