产业结构调整是加快经济发展的核心问题，是经济高速增长的基本推动力量。因此深入研究地区产业结构趋同问题，对于地区产业结构调整以及产业结构高级化发展具有重要意义。本文利用东北三省合并后23个工业产业2001～2014年的工业总产值数据，通过产业结构相似系数、区位熵以及β趋同系数多角度分析东北三省工业产业结构趋同问题。从发展方向看，我国东北三省合并后23个工业产业相似系数最高的是辽宁和黑龙江省，最低的是吉林和黑龙江省，从专业化水平及总量和发展速度关系看，东北三省工业产业在农副食品加工业、交通运输和通用设备制造业形成了区域优势，但在低附加值、产业链低端的开采业以及劳动密集型产业上还存在不同程度趋同，并提出东北三省工业产业在转型升级中应当重点发展高加工度、高附加值等产业，避免产业间的低端雷同的政策建议。%〔Abstract〕 The core of the industrial structure adjustment is to accelerate economic development and become the basic driving force of economic growth . Further study of regional industrial structure convergence problem is of great significance for the regional industrial struc-ture adjustment industrial structure high-level development . This paper deeply analyzes industrial structure convergence of the three north-east provinces through the industrial structure of similarity coefficient , location entropy and the coefficient of beta convergence , using three northeast provinces merged 23 industrial gross industrial output value datum from 2001 to 2014 . From the development direction , the high-est industrial structure of similarity coefficient of combined 23 industrial of three northeast provinces is between Liaoning and Heilongjiang provinces , the lowest of that is between Jilin and Heilongjiang provinces . From the level of specialization and the relationship between amount and speed of development , the northeast three provinces has formed a regional advantage in agricultural food processing industry , transportation , and general equipment manufacturing industry , but there still exists the different degree of convergence in the low value-added , part of the chain industry and labor-intensive industries . At last we put forward some suggestions in the process of the industrial transformation and upgrading , such as focusing on developing high degree of finish , high value-added industries , avoiding the low-end similar industry in the three northeast provinces in China .
