New quality productivity itself is green productivity, and its key to development lies in improving green total factor productivity. How enterprises can adapt to and mitigate the risks brought by changes in trade policies by improving new quality productivity, especially green total factor productivity, is an urgent problem that needs to be solved. This paper explores the relationship between trade policy uncertainty and new quality productivity from the perspective of enterprise green total factor productivity using the DID model, based on the merged data of Chinese industrial and commercial enterprises, customs, pollution, patents, US import tariffs from China from 1998 to 2014, and the Tariff Download Facility database of the WTO. Research has found that: 1) The growth rate of green total factor productivity of enterprises during the inspection period was 4.50%, mainly driven by technological progress.The regional growth rates are: Eastern > Central > Northeast > Western, and the industry dimensions are: High tech > Resource based > Medium tech > Low tech. 2) The significant reduction in trade policy uncertainty has significantly improved the green total factor productivity of enterprises, which is conducive to cultivating and developing new quality productivity. This conclusion remains robust after a series of robustness tests. This promoting effect is more significant in mixed trade, pure general trade, eastern regions, and high-tech industry enterprises. 3) The scale effect, technology effect, structural effect, and income effect generated by the decrease in trade policy uncertainty all exist. The scale effect is mainly achieved through the “quality” of enterprise exports, while the technology effect is jointly achieved through the “quantity” and “quality” of enterprise patents.
