笔者研究了我国地区要素集聚以及由此导致的地区间全要素生产率的差异。通过计算各省就业密度和就业集中度指数发现,在我国的确存在地区劳动力集聚的情况。通过计算各地区的劳均资本存量的绝对差距指数和相对差距指数以及运用马尔可夫转换矩阵的分析,发现我国资本存量在省际间具有明显的两极化趋势。根据面板数据模型估算的结果发现不同地区要素集聚的规模弹性效应差异很大,并且中、西部地区的规模弹性效应对全要素生产率增长的贡献高于东部地区,表明东部地区已经出现要素集聚过度的特征。
筆者研究瞭我國地區要素集聚以及由此導緻的地區間全要素生產率的差異。通過計算各省就業密度和就業集中度指數髮現,在我國的確存在地區勞動力集聚的情況。通過計算各地區的勞均資本存量的絕對差距指數和相對差距指數以及運用馬爾可伕轉換矩陣的分析,髮現我國資本存量在省際間具有明顯的兩極化趨勢。根據麵闆數據模型估算的結果髮現不同地區要素集聚的規模彈性效應差異很大,併且中、西部地區的規模彈性效應對全要素生產率增長的貢獻高于東部地區,錶明東部地區已經齣現要素集聚過度的特徵。

This authors study the regional agglomeration of factors in our country and the consequent difference in the TFP between different regions. Through computing the density of employment and employment concentration ratio of each province, it is found that regional labor agglomeration really exists in our country. Through calculating the index of absolute difference and relative difference in the labor capital in every region and analyzing with the transform matrix of Markov, it is found that the capital stock has obvious polarizing trend in different provinces of our country. Through the analysis with panel data model, it is found that the difference in the effect of scale elasticity of factor agglomeration is great, and furthermore it is found that the contribution of scale elasticity effect to TFP growth in the middle and western areas is higher than in the eastern areas, which indicates that the features of excessive factor agglomeration has appeared in eastern areas.
