Thailand's natural rubber (NR) sector mirrors impressive growth and the limitations on that growth. Thailand is the world's largest natural rubber producer and exporter, employing around one million families or up to six million people, and is the third largest source of export revenues. But the rubber sector also embodies the more general challenge Thai industry of upgrading for raising value added efficiently based on innovation and linkages among (Thai) firms. Most Thai rubber production goes to exports of raw or semi-processed rubber, not downstream, rubber-based products such as for example auto parts.Manufactured products, which incorporate more technology and require more local inputs, generate higher revenues than semi-processed rubber. Therefore because the Thai rubber industry is unevenly developed, it is not generating the skills for linkages and revenues Thailand requires to sustain growth and development over the longer term (Rick Doner and George Abonyi,2013)
