【Abstract】This paper focuses on the promotion impact of the establishment of national-level development zone (economic and technological development zone and high-tech industrial development zone) on city-level firm’s export participation. In the theoretical part, we introduced endogenous thought of firm’s fixed export cost on the basis of Melitz (2003) model, deducing that agglomeration economies reduced fixed export cost and increased the probability of firm’s entering export market. Then, we used DID method to conduct the empirical test towards the above questions by referring to a balanced panel data of 204 prefecture-level cities in 2000–2014 after passing the quasi-experiment test and parallel trend test. The results show that the establishment of Nationallevel Development Zone significantly raises the city-level annual growth rate of the mass of exporters by 15.7%. Considering the timeliness of the policy, the National-level Development Zone has seized an inverted U-shape impact over time on prompting firm’s export participation which reaches the peak in the third year after the experiment, and this promotion effect can last for at least three to four years. The “Switching Treatment Group Test” based on PSM method proves that just the development zone policy has significantly prompted firm’s export participation, and the result of this causality “Placebo Test” is robust regardless of different estimation methods and procedures.

. ① The difference between an economic development zone and a high-tech zone is the supervising department. The two has no fundamental difference in layout design, preferential policies and management systems. Therefore, there is no point in examining the two separately in terms of the effect on firms’ exports (Liu , 2018). [^Back]
. ① Specifically, Xianyang of Shaanxi Province established the Yangling Agricultural High-tech Industrial Demonstration Zone in 1997 and the Xianyang High-tech Industrial Development Zone in 2012, both of which are National National High-Tech Industrial Development Zone. However, the former is an agricultural high-tech zone and is not in manufacturing and export industries which are the subject of this paper. Therefore, Xianyang is deemed to obtain approval for a national high-tech zone in 2012. [^Back]
. ① During the selection of the control group cities, Sansha and Haidong, two prefecture-level cities established in 2012 and 2013, and Chaohu, a city removed from the prefecture-level divisions in 2011 are excluded, retaining the rest 89 prefecture-level cities with no national economic development zones or high-tech zones.
