摘要
多样化可以作为知识溢出的来源,也可以作为地区经济的投资组合策略,与地区经济发展密切相关。本文选取我国制造业中28个大类以及其中的125个中类测量了我国22个省或直辖市的制造业相关多样化和不相关多样化水平,并实证检验了制造业多样化水平在我国地区经济发展中的作用。研究表明,相关多样化和不相关多样化对就业增长率都具有显著的正面影响,对劳动生产率的影响则不显著。另外多样化与经济发展的关系在我国东部地区和中西部地区之间存在明显的差异。
The economic variety closely related to regional economic growth could be regarded as a source of regional knowledge spillovers, and also as a portfolio protecting a region from external shocks. The paper selects 28 big kinds of 30 manufacturing industries and 125 medium kinds to get the level of related variety and unrelated variety for 22 selected provinces. The empirical study demonstrates that both related variety and unrelated variety are positively related with the employment growth, but can not significantly promote the labor productivity growth. The study also shows that the role of variety to the economic development is different among eastern region, central region and western region.
