香港离岸贸易对珠三角地区产业发展的影响研究——基于珠三角地区48个区县面板数据的实证分析

The Impact of Hong Kong's Offshore Trade on the Industrial Development of the Pearl River Delta Region: An Empirical Analysis Based on the Panel Data of 48 Counties in the Region

目前,香港离岸贸易额已超过转口贸易,成为其第一大贸易方式。作为离岸贸易的主体,香港贸易中间商通过离岸贸易的方式对珠三角地区的产业发展产生信息网络效应、市场创造效应和经济催化剂效应。将离岸贸易因素纳入传统的Cobb-Douglas生产函数模型,对珠三角地区48个区县的面板数据进行实证分析。结果表明:香港离岸贸易对珠三角地区产业的总体发展具有显著的促进作用;同时,香港离岸贸易对珠三角地区中心城市服务业发展的促进作用要明显大于制造业,与之相反的是,香港离岸贸易对珠三角地区非中心城市制造业发展的推动作用要显著大于服务业。

At present, the offshore trade volume of Hong Kong has exceeded its re-export trade volume, which means the offshore trade has become the main trade pattern of Hong Kong. As the main body of Hong Kong＇s offshore trade, international trade intermediaries have effects of information network, market creation and economic catalytic contribution on the industrial development of the Pearl River Delta region by way of offshore trade. This paper adds the factor of offshore trade into the traditional Cobb-Douglas production function model, and empirically analyzes the panel data of 48 Counties in the region. The results show that Hong Kong＇s offshore trade has a significant role in promoting the overall industrial development of the region; the promoting effect of Hong Kong＇s offshore trade on services in the region＇s center cities is significantly greater than that on manufacturing, and in contrast, the boosting effect of Hong Kong＇s offshore trade on manufacturing in other cities is dramatically greater than that on services.
