Policy Tourism and Economic Collaboration Among Local Governments: A Nonparametric Matching Model

Policy tourism is an important, widespread, but understudied aspect of the networking efforts of public managers. Few studies have investigated how the official and purposeful interactions between public managers in the context of policy tourism affect collaboration. To fill this gap, this article aims to explore the question: To what extent does policy tourism channel economic collaboration? We argue that leaders' visit paths provide a direct channel for collaboration through information exchange, trust building, and integration of regional policies, but the consequences vary between jurisdictions at different levels of economic development. We adopt a newly developed nonparametric matching method to estimate the marginal average treatment effects of policy tourism on interprovincial trade flows in China from 2000 to 2013. Results demonstrate that policy tourism channels interprovincial trade flow significantly and that the impacts decrease over time. Also, policy tourism affects interprovincial trade flow more significantly when initiated by less-developed jurisdictions.
