中低技术制造业集聚、创新与地方经济增长——基于木材加工业的实证分析

创新驱动是国家重大战略部署，中低技术制造业是我国制造业的主体，那么创新在中低技术制造业中扮演着怎样的角色？文章对产业集聚、创新和地方经济增长三者的关系提出了三个假说，构建了一个由创新担当中介作用的互动关系模型，并以木材加工业两个细分行业的企业数据为样本检验假说。回归结果表明：LMT制造业的创新活动对地方经济增长的影响与该行业所处的价值链位置有关。中间品行业集聚虽然有助于提高企业创新水平，但是这些创新活动并不能显著促进地方经济增长，终端产品行业的创新活动则能够显著提升地方经济增长。

Agglomeration of Manufacturers of Low-and Medium-Level Technology,Innovation and Local Economic Growth: Empirical Analysis of the Wood-processing Industry

Innovation-driven development is a major strategic deployment of the country. Low-and Medium-technology (LMT) manufacturing industry is the main body of China’s manufacturing industry. What role does innovation play in the LMT manufacturing industry? In this paper, we put forward three hypotheses based on the relations of industrial agglomeration, innovation, and the local economic growth. We then built a mediation model and used two subsector data from the wood processing industry to test the hypotheses. The results showed that the influence of innovation on local economic growth was affected by their positions in the value chain. Only the innovation activities of the end-product subsector could significantly improve the local economy. Moreover, the improvement of the innovation activities in the intermediate-product subsector were limited.
