Industrial estates offer land for rent or purchase to industrial and commercial businesses, as well as supply businesses in the estates with access to amenities and utilities including electricity, water, flood mitigation systems, and centralized sewage services.
In Thailand, industrial estates are regulated by the Industrial Estate Authority of Thailand (IEAT). They manage (i) industrial estates that the IEAT owns and operates alone, and (ii) industrial estates that the IEAT owns and operates in partnership with private players.
In addition, there are industrial parks and industrial zones – these share the characteristics of industrial estates but are privately-owned and operated. Examples include sites operated by Rojana Industrial Park and Navanakorn. These come under the Board of Investment which has delegated the regulatory task[1] to the Department of Industrial Works in each province.
Industrial estate operators derive income from two principal sources: (i) leasing and selling land, and (ii) providing utilities and other services, and leasing out factories and warehouses, all of which generate recurring income and reduces the impact of volatile income from the sale of land. The revenue structure of two major industrial estate operators are shown in Figure 1.
Most businesses prefer to secure sites in industrial estates rather than build from scratch on empty land, because the former is equipped with the necessary infrastructure, utilities and transportation links. Locating operations in industrial estates could also benefit companies financially in the form of government incentives such as tax relief or investment support. The two major industrial estate operators in Thailand are Amata Corporation which operates Amata Nakorn, and WHA Group. Rojana Industrial Park and Navanakorn are the most important operators of industrial parks and industrial zones.
The critical factors that influence the growth of the industrial estate sector are: (i) infrastructure and services available within the estates; and (ii) appropriate regulations to support investment in domestic industrial estates, and the concessions and incentives offered to investors in the sector. Beyond this, the wider environment also affects the sector. They include: (i) the state of domestic and international economies and local political condition; (ii) multinational companies’ approach to investing and establishing production facilities in Thailand; and (iii) physical condition and geographical location of the country.
In September 2019, there were 59 industrial estates in Thailand, spread across 16 provinces (Figure 2). Of this, 14 were operated by the IEAT and the remaining 45 were joint-ventures with the private sector. The eastern region housed the vast majority (76%) of these (Figure 3), followed by the central area (including Bangkok Metropolitan Region) with 16%. Between 2013 and 2018, total industrial estate land – including new estates and expansion of existing estates – increased by only 3.3% (Figure 4). The slower supply growth was due to operators waiting for more clarity on new investment policies at that time.
Looking at the investor profile, Japanese are the largest group of investors in Thai industrial estates based on investment value (Figure 5).
Eastern region: This area has the greatest potential for growth because it is home to a wide range of major industries, including oil refining and petrochemicals, chemicals, auto assembly and auto parts manufacturing, electronics, and food processing. Because of this, the region receives a substantial portion of government support for the sector. This has resulted in the eastern region having the highest concentration of industrial estates in the country, and attracting the most investors. The eastern region includes the Chonburi, Rayong, Chachoengsao, Prachinburi and other provinces. But for some time now, manufacturers operating in industrial estates in other provinces have been relocating their factories to this area because of connections to the Eastern Seaboard Development Program and an established communications network. The area has convenient road transport connections, is close to air links (Suvarnabhumi and U-Tapao airports) and commercial ports (Laem Chabang and Map Ta Phut), and Bangkok is nearby and easily accessible.
In addition, Chonburi, Rayong and Chachoengsao have been designated a part of the Eastern Economic Corridor (EEC) development (Figure 6) because they have good infrastructure. And because of this, public- and private-sector players can move in and start operations immediately. The EEC development will help attract interest from investors, and the government is hoping to attract investments in the 10 targeted industries[2], all of which are technologically and capital intensive.
Bangkok and Central region: This region benefits from its location, as the center of manufacturing and national transport and communication networks. The central region includes Bangkok which is home to the most expensive industrial land in the area, and provinces with important industrial estates, including Samut Prakan, Ayutthaya, Saraburi, Ratchaburi and Samut Sakhon. Previously, auto parts, electrical appliances and electronics manufacturers had been concentrated in the area, along with industries that utilized local resources, such as food processing and construction materials. The region is still home to a large number of SME factories. However, industrial estates in the region had been badly affected by severe flooding in 2011 and demand (rent and sale) for industrial space in the region reached only 8.6% and 4.8% of the national total in 2012 and 2013, respectively. The situation has improved since, and between 2014 and 2018, they reached double-digit. This illustrates the continued ability of industrial estates in the Bangkok Metropolitan Region and wider central zone to attract investors (Figure 7).
Northeast and Northern regions: Industrial estates in these areas generally host food processing industries and some electronics manufacturers. However, communication links are inferior to those in other parts of the country, and this has curbed interest from investors. However, progress in developing communications in the northeast and links between northern Thailand and Myanmar and China should stimulate future investment. Most of the industrial estates are located in the northeastern provinces of Udon Thani and Nong Khai (these are currently being developed and expected to be operational in the near future) and in the northern provinces of Lamphun and Phichit.
Western region: This area, which includes Ratchaburi, will see more developments soon. The Industrial Estate Authority of Thailand plans to develop an industrial estate to support and connect to the proposed new industrial zone and deep-water port in Dawei, Myanmar.
Southern region: This region is being developed to improve connections between southern Thailand and Malaysia. The major industry here is rubber cultivation. Currently, it is host to only one industrial estate (in Songkhla). In 2016, the IEAT decided to halt development of a planned new industrial estate in Pattani province to house halal food processors, because of weak interest from both Thai and international investors due to lingering unrest in the region. The ongoing unrest in the deep south and insufficient electricity supply suggest little prospects to develop industrial estates in this area.
Cost of land (for both leasing and sale) varies among industrial estates and depends on several factors such as location, quality of utilities services, travel links, and access to raw material (Figure 8). Bangkok’s location in the center of land, water and air travel networks means that industrial estate land in the Bangkok Metropolitan Region is the most expensive in the country. This also pushed up land prices in adjacent areas such as Samut Prakan. Space in the EEC (Chonburi, Rayong and Chachoengsao) is the second most expensive in the country. In the second half of 2017, prices in these 3 provinces rose as high as THB8m/rai, about 30% higher than in the second half of 2014 (THB5.3m/rai) before the government stepped up efforts to promote the EEC (source: Colliers International). This suggests there is potential for future development in the area, which is an important factor to attract investors and government support.
In 2012, the total area of land sold or leased in industrial estates surged, especially in the eastern region. This was driven by severe flooding of 4Q11 which prompted foreign operators to move production facilities to industrial estates in the east of the country, and the decision by Japanese corporations to shift operations to Thailand following the 2011 Tohoku earthquake and tsunami.
Between 2013 and 2015, the industrial estates sector was in a depressed state, and sale and rent of industrial space declined (Figure 9). The negative market conditions were caused by: (i) sluggish exports, which then weighed on the economy; (ii) drawn out domestic political conflicts between 2010 and 2014, which discouraged investors; and (iii) more stringent environmental[3] and health[4] impact assessment process, partly triggered by the serious air pollution at Map Ta Phut Industrial Estate in 2007 which also hurt investment especially in heavy industries and large-scale operations.
In 2016 and 2017, investment remained subdued. Land sale and leases in industrial estates shrank (Figure 9) as businesses waited for greater clarity on government policy, progress in investment in new infrastructure, and for the general economy to turn around. Hence, in these two years, private sector investment rose by just 0.6% and 2.9%, respectively, and land sale and leases in industrial estates nationwide shrank by 21.4% and 10.0%.
In 2018, investment started to pick up but land sale and leases continued to worsen.
In 2018, there were 1,626 applications for BOI incentives. Although this represents only 3.1% growth, the total value of applications jumped by 43% to THB900bn. The bulk of these (77%) were for projects in the eastern region, which total value increased at an even faster rate of 134% to THB690bn (Figure 10). This suggests the eastern region still appeals to investors and there is still growth potential. There is especially strong interest in the EEC, where the number of applications had dropped by 3.2% to 422 projects but investment value has surged by 137.4% to THB680b. Within this area, Chonburi received the most applications and highest investment value (Figure 11).
Krungsri Research forecasts that between 2020 and 2022, the industrial estate sector will see strong growth and land sale and leases will rise by an average of 10-15% p.a. to 2,500-3,000 rai (Figure 16). This outlook is supported by the following factors.
However, operators in some areas might see limited growth due to the following.
Demand for industrial estate space (buy or rent) will grow in the coming period but operators’ income will vary by area. The outlook for the major regions are given below.
[1] The principal differences between on the one hand, industrial estates and on the other, industrial parks and zones, are that: (i) foreign companies may purchase land in industrial estates without the approval of the BOI, but may not do so in the case of industrial parks and zones; and (ii) the IEAT acts on behalf of businesses on industrial estates as the certifier and provider of a variety of services, such as issuing permits to build and to operate factories, and thanks to its being a government agency, it is able to have applications to the Department of Industrial Works for these processed more smoothly and more rapidly than can private sector operators. In the case of industrial parks and zones, conversely, the operator of the park/zone will itself be responsible for handling these services on behalf of the lessees or purchasers.
[2] The ten targeted industries are: (i) next-generation automotive industries; (ii) smart electronics; (iii) affluent and wellness tourism; (iv) agriculture and biotechnology; (v) food for the future; (vi) automation and robotics; (vii) aviation and logistics; (viii) biofuels and biochemicals; (ix) digital industries; and (x) medical hub-related.
