As great as this sounds, one significant caveat is that it all assumes that Mongolia will source all the additional demand for goods and services domestically to fully benefit from the investment. This assumption, however, can be easily challenged. In reality, Mongolia may have to source inputs from other countries due to the limited supply domestically.
Since Mongolia is significantly dependent on import and export activities with its close neighbors, the People’s Republic of China and Russian Federation, the expected economic boost may leak as Mongolia imports inputs. Some of Mongolia’s economic sectors are importing a large share of their inputs – more than 40% of inputs are imported in mining, transportation, and construction sectors.
In this case, most of the additional income would be spent abroad, or the additional employment would be sourced from abroad—most likely the People’s Republic of China and Russian Federation. The same analysis suggests that the indirect spillover benefit of the Inner Mongolia project to Mongolia could be much lower, with the gross output change scaled back by 4% and the employment by 9%.
An example of where receiving areas have the capacity to maximize the spillover benefits can be found in the Greater Mekong region, where the benefits were found to be the highest when the projects connected large cities, e.g. the Southern Corridor that includes three large economies—Bangkok, Ho Chi Minh City, and Phnom Penh—along its relatively short length (about 900 kilometers), which have better absorptive capacity to respond to the new demand for inputs and labor.
For Mongolia to replicate this success along its border with the People’s Republic of China, policy makers should consider public investment in transportation and storage infrastructure that will support logistics operators and suppliers. In this regard, ongoing efforts with ADB to modernize logistic facilities in Zamyn-Uud economic zone are encouraging, particularly as this is across from the Erenhot economic zone and the main gateway for Mongolia’s trade with the People’s Republic of China and other parts of the world.
Despite this progress, Mongolia’s relatively high wage levels remain a bottleneck and need to be addressed by matching the required skill types and levels to those in the neighboring countries.
An important takeaway is that the extent of benefit an investment project in one country brings to a neighboring country depends also on the absorptive capacity. The gains are not automatic. Even when the project is designed to benefit the other country, the maximum benefit would not be always achieved.
In order to fully realize both direct and indirect benefits from border investment opportunities, the adjacent benefiting country will have to be ready to absorb the benefits by developing its own input markets and human capital. In particular, its limited infrastructure and the seasonality of many inputs combined with a poor storage capability make it challenging to establish a reliable supply chain.
