Extended data:

Texas is famous for its energy and petrochemical industries, and is the largest energy and chemical state in the United States. The output of oil and natural gas accounts for 1/3 and 1/4 of the national output respectively, and the refining capacity accounts for the top 1/4 of the national output.

Since 1980s, Texas has been pursuing the policy of economic diversification. Although oil and natural gas are still the main industries in Texas, their proportion has declined, and high-tech industries have developed rapidly. The triangle of Houston, San Antonio and Dallas has become the second "Silicon Valley" in the United States, and Houston has developed into the largest medical training and treatment center in the United States and even the world. The corridors between Houston, Dallas-Fort Worth, San Antonio and Austin and the border between Texas and Mexico have become the fastest growing metropolitan areas in the United States.
