This paper examines production efficiency of coastal region and non-coastal region in Mainland China between 2000 and 2010 using one-step stochastic frontier analysis and two-step metafrontier model. Unlike previous studies, this study not only discusses production efficiencies but also considers differences in production patterns. The empirical results indicate that coastal region has better production performance in metafrontier technology efficiency (MTE) and technology gap ratio (TGR). In addition, this study finds that the gap of MTE and TGR between coastal region and non-coastal region is increasing for the past years.  相似文献

对外开放与能源利用效率:基于35个工业行业的实证研究   总被引:10,自引:0,他引:10  
中国对外开放和能源利用效率都不断提高。本文先从理论层面探讨对外开放影响能源利用效率的一般机制,然后利用1999-2005年中国35个工业行业的面板数据进行经验研究。回归结果表明,对外开放对能源利用效率的提高具有积极影响。能源强度结构分解结果表明,对能源利用效率提高起主要决定作用的7个高耗能行业,除化学行业外,对外开放度都远低于全部工业的平均水平。因此,在保证国家经济安全的前提下,中国可适度加大高耗能行业的对外开放。  相似文献

We examine the effects of international trading activities of firms on creating productivity gains in Turkey by using a recent firm-level data set over the period 2003–2010. We establish treatment models and investigate the productivity improvements of firms through trade by using propensity score matching techniques together with difference-in-difference estimates. Three different groups of treatment are constructed: (1) firms that are involved only with import activities, (2) firms that are involved only with export activities and (3) firms that are involved with both export and import activities. The results of the study suggest that both exporting and importing have positive significant effects on total factor productivity (TFP) and labour productivity (LP) of firms. Importing is found to have a greater impact on productivity of firms compared to exporting. Further, two-way trade is found to have more significant effects than those of one-way trade on firm productivity. Finally, our results indicate that international trade has greater impact on LP rather than TFP of firms.  相似文献
