1) To enhance national competitiveness since the country's long pause in mega project investment has made other countries’ development far ahead of Thailand.
2) To make Thailand a strategic hub connecting ASEAN and its 600-million citizens under the conceptual framework of ‘connectivity’. This will subsequently create opportunities for income generation and stabilize Thailand as the ASEAN’s investment hub.
3) Thailand lacks comprehensive land and waterway connectivity, for example, connection of water source where raw materials are with middle of the waterway that locates industries, and with the end of waterway for export. This would reduce logistic cost as well as shorten the distance which results in fresher products and less possible losses.
4) To connect tourist attractions of various provinces, such as Chiang Rai- Chiang Mai- Mae Hongson- Kampaeng Phet- Sukhothai- Tak- Uttaradit, in order to equally spread prosperity and to draw tourists to stay longer in the country.
5) To increase options for the people on transportation connectivity with high-speed railway system in order to reduce transportation cost, and spread prosperity to the rural areas which will be in accordance with a national strategy. This will also result in more national income, and less disparity among the people.
The two -trillion-Baht investment will help reduce costs of transportation by 2% and increase GDP by 1% annually, as well as 500,000 jobs during the course of investment which will subsequently reinforce economic circular flow.
