摘要: 基于中国工业企业数据库和海关贸易数据库对制造业企业出口国内附加值率进行了测算,并实证分析了长江经济带经济集聚对地区制造业出口升级的影响及其作用机制。结果表明:经济集聚显著促进了制造业企业出口国内附加值率的提升,且在经济集聚程度高的地区提升效果更好。在长江中上游地区经济集聚带来的促进效应并不理想,而在长江下游地区和上游沿江中心城市则提升效果显著。同时,经济集聚有助于提高一般贸易和混合贸易企业出口国内附加值率,且存在推动加工贸易企业向高附加值一般贸易企业转变的可能。机制检验表明经济集聚是通过促进地区信息化发展和国内中间品投入比例的提高实现出口国内附加值率的增加。此外,地区经济集聚有助于推动国内中间品市场的扩大和深化企业国际化参与度。就外部性影响来看,要素市场的成熟和市场服务的完善也有助于强化经济集聚对制造业出口升级的促进效应。

Abstract: Based on the data from China Industry Business Performance Data and China Customs Trade Database, this paper conducts a measurement of the domestic value-added rate (DVAR) of the enterprises’ export in the manufacturing industry and empirically analyzes the impact of economic agglomeration of Yangtze River Economic Belt on the export upgrading of regional manufacturing industry and its action mechanism. The results show that economic agglomeration has significantly promoted the DVAR of export of manufacturing enterprises, and this effect is better in the regions with higher level of economic agglomeration. In the upper-middle reaches of Yangtze River, the promotion effect brought by the economic agglomeration is not ideal, while the effect is significant in the lower reaches of Yangtze River and the central cities there along the river. Meanwhile, economic agglomeration helps to improve the DVAR of general trade and mixed trade exports. It is also possible that trade processing enterprises will be pushed to transform into general trade enterprises with higher added value. The results of the mechanism tests indicate that it is through promoting the regional information development and increasing the input ratio of domestic intermediate products that economic agglomeration can increase the DVAR of exports. Furthermore, regional economic agglomeration can help to expand the domestic intermediate products market and deepen the international participation of enterprises. In terms of external influences, the maturity of factor markets and the improvement of market services can also help to strengthen the promoting effect of economic agglomeration on the upgrading of manufacturing exports.

Key words: economic agglomeration, Yangtze River Economic Belt, domestic value-added rate of exports, information development, domestic intermediate products input
