本研究通过对日本微观数据的分析，证明了地方经济中的大型核心部门（专业部门或制造业部门）提高了地方非贸易服务部门的生产率，从而增加了就业。服务部门需求的规模取决于当地经济的规模，而当地经济又取决于这些大型核心部门。核心部门通常是具有可交易商品和服务的部门，其需求不受当地市场规模的限制，因为其商品和服务供应多个地区。对服务部门的大量需求导致竞争加剧，并通过达尔文式的选择或公司内部效率的提高了生产率。此外，核心部门的溢出效应可能会影响当地服务部门。因此，在上一次推算期间，专业部门增加值每增加1%，专业部门增加值变动每增加1%，制造业增加值每增加1%，服务业生产率将分别提高约4- 5%、4%和2.5%。此外，在专业部门增加10万美元的附加值，在当地服务部门增加26名雇员。此外，本研究证实了企业内部的效率提高作为一种生产率机制。
Examining Japanese micro-data, this study demonstrates that large core sectors (specialized or manufacturing sectors) in a local economy improve the productivity in the local non-tradable service sectors, and thereby increase employment. The size of service sector demand is determined by the size of the local economy, which, in turn, is determined by these large core sectors. The core sectors are generally sectors with tradable goods and services and their demand is not limited by the local market size as their goods and services supply multiple regions. A large demand for the service sectors induces heightened competition and improves their productivity through Darwinian selection or efficiency improvements within firms. Moreover, the spillover effect from core sectors might affect local service sectors. As a result, a 1% increase in added value in the specialized sectors in the previous estimation period, as well as a 1% increase in the change in added value in the specialized sectors, and a 1% increase in added value in the manufacturing sectors in the previous estimation period affect an increase in the productivity of the service sectors by approximately 4–5, 4 and 2.5%, respectively. Moreover, an increase of 100 thousand dollars of added value in the specialized sectors increases employment by 26 employees in the local service sectors. Furthermore, this study confirms efficiency improvements within firms as a productivity mechanism.
