内容摘要:文章在新经济地理框架下构建理论、计量模型及内外市场需求测度,运用2003—2011年284个地级及以上城市面板数据检验了国内、国际市场潜力和产品多样化对城市劳动生产率的影响。结果表明,我国各城市间整体上互为商品市场,存在显著的需求关联效应;国内、国际市场需求和产品多样化均显著促进了城市劳动生产率的提高,且国内市场潜力加强了产品多样化的影响效果。国际市场潜力对城市劳动生产率的贡献率明显低于国内市场潜力。各地区国内市场潜力、产品多样化及其交叉项系数均显著为正,且由东向西依次递减;国际市场潜力显著提高了东、西部劳动生产率,但不利于中部劳动生产率的提高;国内、国际市场对劳动生产率的影响作用在东、西部存在互补性,而在中部地区具有替代性。

  摘  要:文章在新经济地理框架下构建理论、计量模型及内外市场需求测度,运用2003—2011年284个地级及以上城市面板数据检验了国内、国际市场潜力和产品多样化对城市劳动生产率的影响。结果表明,我国各城市间整体上互为商品市场,存在显著的需求关联效应;国内、国际市场需求和产品多样化均显著促进了城市劳动生产率的提高,且国内市场潜力加强了产品多样化的影响效果。国际市场潜力对城市劳动生产率的贡献率明显低于国内市场潜力。各地区国内市场潜力、产品多样化及其交叉项系数均显著为正,且由东向西依次递减;国际市场潜力显著提高了东、西部劳动生产率,但不利于中部劳动生产率的提高;国内、国际市场对劳动生产率的影响作用在东、西部存在互补性,而在中部地区具有替代性。

  Based on the framework of new economic geography, this paper constructs theoretical and econometric models and domestic and international market potential measurements, and employs the panel data of 284 cities at prefecture level or above from 2003 to 2011 to test the effects of domestic and international market potential and product diversification on urban labor productivity. It draws the conclusions as follows, firstly, as a whole, there exist mutual commodity markets among cities and there are significant demand-associated effects; secondly, domestic and international market potential and product diversification significantly improve urban labor productivity, and domestic market poten- tial strengthens the effects of product diversification; thirdly, the contribution of international market potential to urban labor productivity is significantly lower than the contribution of domestic market po- tential; fourthly,the coefficients of domestic market potential, product diversification and their cross- term are significantly positive and descend successively from eastern to western China; fifthly, interna- tional market potential improves labor productivity in eastern and western China, but is not conducive to the increase in labor productivity in central China; sixthly,domestic market is complementary to in- ternational market in eastern and western China while domestic market is a substitute for international market in central China.
