We investigate the causal relationship between foreign ownership and international trade performance by comparing foreign-acquired firms with similar domestic-acquired firms in China with regard to changes in their post-acquisition international trade *** findings indicate that foreign ownership significantly enhanced the probability of both exporting and importing,and strongly increased trade *** ownership took effect from the year of the acquisition and persisted for at least 2 *** stimulated both processing trade and ordinary trade,and expanded products and trading ***-acquisition trade performance also exhibited heterogeneity based on the different pre-acquisition and post-acquisition *** for the underlying mechanisms,we show that firms experienced significant output expansion,increased export dependence,and eased financial constraints after foreign acquisition.

We are on the cusp of a new era,with the global pop-ulation surpassing 8 billion,and over half relying on riceas their staple food(Sasaki and Burr,2000).Despite thisgrowing demand,rice yield per unit has seemingly plateauedfor many years(Song et al.,2022).This stagnation raisesserious concerns about future global food security,especiallyconsidering the shrinking arable land in many countries.

Cultural symbols,a manifestation of cities’cultural resources,are not only signs that frame concepts but also forms that express *** the international communication of cities from the perspective of symbols,this paper analyzes in depth how cities create their cultural symbols in the dynamic process of international communication in an era of symbol-based digital media,and how they develop their narratives and explain meanings through the dissemination of symbols when telling their stories to international audiences,thus enhancing the efficiency and effectiveness of their international communication efforts.
