In the first half of this year, Shanghai's export reached 80.498 billion US dollars, an increase of 25.12% over the same period of last year. The growth rate was not only 4.2 percentage points higher than the same period of last year, but also 3.2 percentage points higher than the national export growth level in the first half of this year. Information from the customs shows that in the first half of the year, Shanghai's foreign trade export growth rate was higher than that of the whole country. First of all, it was due to the relatively optimized industrial structure, the high proportion of high-tech and electromechanical products, and the low proportion of high pollution, high energy consumption, resourceful "two high and one capital" products and low value-added products, In recent years, a series of policy adjustments, such as national processing trade restrictions and export tax adjustments, have had a weaker impact on Shanghai's exports than the whole country. Compared with exports, the growth rate of imports in Shanghai in the first half of the year was relatively low, mainly because Shanghai enterprises had less dependence on primary materials, and the proportion of energy and resources imports in similar products in the country was low.
