产业集群与区域经济增长的实证研究

Exemplary research of industrial colony and the growth of regional economies:Based on comparative analysis of Zhejiang and Shaanxi

为了论证区域经济增长的产业集群效应,以浙江和陕西两省2000—2006年经济发展和产业集群的相关指标为变量,在迪克希特—斯蒂格利茨框架下,运用向量自回归(VAR)模型、Granger因果检验等方法,建立多元线性回归模型、对数线性模型(log-linear)和误差修正模型(ECM),对两省专业化分工和产业集群的经济效应进行了实证研究后认为:无论是从绝对量还是相对量看,城镇居民可支配收入是促进浙江、陕西两省经济增长的共同原因。专业化分工水平在陕西省经济增长中的作用不如固定资产投资增长的作用显著。浙江、陕西两省的地方化优势产业及其经济发展的实践,验证了区域经济增长和产业集群成长正相关假设的正确性。因此,陕西经济的振兴,必须高度重视产业集群,尤其是中小企业集群的发展,继续拓展区域创新体系,进一步提升以创新为主的知识密集型产业的发展。

In order to probe the relationship between industrial cluster and the growth ot regional economy,me raterrelated index of economic development and industrial cluster in Zhejiang and Shaanxi from 2000 to 2006 was taken as variables under the frame of Dick Hyatt - Stieglitz, utilizing the model of VAR and Granger test, establishing the multi - dimensional linear regression model and the log - linear model and the error correction model （ ECM ）. After the empirical research it is urgued that regardless of look from the absolute value or the relative quantity, the common reason shows that control income of town dwellers will promote economic growth in Zhejiang and Shaanxi. Besides, the growth of the fixed assets investment makes more important role in the economic growth of Shaanxi province than the growth of regional specialization index （ （ location quotient）. The location quotient of the Shaanxi Province economic growth＇s function is inferior to the investment in the fixed assets grows. The localization superiority industries and regional economies＇ development in Zhejiang and Shaanxi has confirmed that the regional economies growth and the industrial cluster is being related. Therefore, paying attention to the development of industrial cluster, particularly the medium - sized enterprises＇ cluster, continues to develop the region innovation system, further promotes the development of knowledge intensity industry, in order to promote Shaanxi＇ s economic development.
