The Board of Investment (BoI) plans four months of roadshows to push its new investment promotion policies to local and foreign investors.
The roadshows, aimed at explaining its new seven-year strategy starting next year, will begin in mid-December in major provinces such as Chiang Mai, Songkhla and Khon Kaen.
Abroad, the roadshows will move to Japan in next year's first quarter, acting secretary-general Hirunya Suchinai said.
The BoI, which promotes investment from local entrepreneurs and foreign investors alike, has outlined fresh investment promotions for the Thai economy's new high-technology strategy.
Current investment promotions provide zone-based incentives, but the new focus will be on projects that use high technology, research and development, design and industrial clusters in each region.
Investment promotions for 2015-21 received cabinet approval to raise the competitiveness of Thai industries, Ms Hirunya said.
"This policy is aimed at making Thailand a more attractive investment destination."
Activities eligible for promotion under the new strategy have been categorised as groups A and B.
The A-category investments will receive corporate tax exemption for activities deemed to be of high importance or knowledge-based investments even if they are not capital-intensive, as they could be crucial to the country's long-term competitiveness.
High-tech activities, complicated production processes and capital-intensive investments all fall into the A group.
B-group investments are not exempt from corporate income tax but can qualify for duty exemptions on imported machinery and raw materials for the manufacture of exports as well as non-tax incentives such as permission to own land.
Ms Hirunya said the government expected to increase the value of investment approvals by 30% over the seven-year period, while the BoI expected the value of R&D to rise by at least 20 billion baht a year.
The A group will include the software and animation industries as well as design and development projects deemed to improve Thailand's competitiveness.
