【摘要】：当前我国经济正处于重要的转型期,扩大内需是新形势下经济增长的主要动力和重大的结构调整。本文从需求驱动生产的角度,探讨内需份额对各区域产业集聚的影响。研究基于排除不合理的计价物假设的本地市场效应(HME)模型得出与传统模型不同的结论:HME呈现为"凹——拐点——凸"的非线性特征,即在市场份额较大或较小的区域中HME更明显。本文利用2002年和2007年中国区域间投入产出表中8区域16部门的数据集,通过计算地区间贸易自由度来测度各区域潜在内需,实证内需对各区域产业集聚的影响是否存在非线性HME。结果表明,在控制外需因素后,内需导致的HME显著存在,但仅呈现斜率近似为1.04的线性特征,说明我国内需尽管能推进产业集聚但效果不强,且对不同内需规模的区域影响并无显著差异。
[Abstract]:At present, China's economy is in an important period of transition, expanding domestic demand is the main driving force and major structural adjustment of economic growth under the new situation. From the point of view of demand-driven production, this paper discusses the effect of domestic demand share on regional industrial agglomeration. In this paper, the local market effect (HME) model based on excluding unreasonable pricing hypothesis is studied. The conclusion is different from the traditional model. The conclusion is that the "concave inflection point convex" is the nonlinear characteristic of the (HME) model. That is, in the larger or smaller market share of the region HME is more obvious. Based on the data sets of 16 sectors in 8 regions in the input-output table of China in 2002 and 2007, this paper measures the potential domestic demand in different regions by calculating the degree of freedom of inter-regional trade, and demonstrates whether there is a nonlinear HME. in the influence of domestic demand on regional industrial agglomeration. The results show that after controlling for external demand, HME caused by domestic demand exists significantly, but only presents a linear feature of slope approximately 1.04, which indicates that domestic demand in China is not effective although it can promote industrial agglomeration. Moreover, there is no significant difference in the regional influence of different domestic demand scale.
