Shifting supply chains boost trade in California-Baja mega-region

Foreign companies looking to diversify their supply chains have increasingly been choosing Mexico’s northern and central states in recent years.

One of the biggest beneficiaries of the evolving global trade flows has been the so-called Cali-Baja mega-region, the border area connecting Southern California and the northern portion of the Mexican state of Baja California.

“This kind of movement and trend started after the pandemic, where the companies started decoupling, fragmenting their supply chains, putting their eggs in different baskets for production,” Bertha Martinez-Cisneros, a logistics professional and educator, told FreightWaves. “These companies decided to start looking for places around the world. I think that in the case of Mexico, and especially Baja California, it’s kind of like the stars aligned, because we have a very privileged geography.”

Martinez-Cisneros is the coordinator of the bachelor’s degree program in international logistics at the Center for Technical and Higher Education, a private university in Mexicali, Mexico, in Baja California. In addition to teaching, Martinez-Cisneros has held management positions in international logistics and operations for Acer Inc. and Sony Corp. in Mexico.


“Baja California is on the border with the United States, but we also have the coastline along the Pacific, so we can receive shipments directly from vessels from China,” Martinez-Cisneros said. “We are also very close to Los Angeles and Long Beach, which are the main ports in the U.S., and one of the main ports in the U.S. for receiving raw materials and products from Asia.”

The Cali-Baja mega-region is the most extensive integrated economic region along the U.S.-Mexico border, according to a 2022 study from the University of San Diego. The region comprises the two southernmost counties in California (San Diego and Imperial) and the Mexican cities within Baja California (Ensenada, Mexicali, Rosarito, San Quintin, Tecate and Tijuana).

In 2020, the Cali-Baja region boasted a regional GDP of around $250 billion and an estimated $70 billion in cross-border trade flows, the study said.
