Indonesia is currently enjoying rapid development in the telecommunications sector despite the economy having been heavily dependent for almost four decades on the two largest sectors: the manufacturing industry and trade. The telecommunications sector has played an important role in stimulating economic growth in the country during the last few years, with an annual growth rate higher than that of other sectors. This contribution is supported to a great extent by the rapid diffusion of telephony, in particular cellular telephony, as the number of subscribers increased from just 2.1 million in 1999 to 170 million in 2011. Previous studies investigating the impact of the telecommunications sector on the economy aggregate the impact of the sectors on Gross Domestic Product (GDP) without further scrutiny of what sources of growth telecommunications has contributed. Hence, an interesting question arises as to whether the achievement of cellular diffusion is also followed by structural change in the telecommunications sector. That said, this study aims to decompose the output of telecommunications into several sources of growth: domestic final demand, export effect, import substitution effect and technological coefficient effect. A particular interest in this study is to compare the source of growth concerning domestic final demand and the technological coefficient effect The main tool for analysis in this study is the Input-Output (IO) method, while the time series of the investigation covers the period 1975-2008, allowing comparison of structural changes in the telecommunications sector between the pre- and post-cellular eras. The study found that the coefficient multiplier of the telecommunications sector, which was approximately 1.8 during the 1980s, had decreased to only 13 by the end of 2008. Consequently, the final demand from the telecommunications sector contributed less to economic output in the late 2000s compared to the impact in the 1980. Moreover, the cellular era that started in the early 2000s also brought about a trend of changes in telecommunications output While final demand remains very dominant the technological coefficient effect has diminished as the source of telecommunications output This finding indicates a lower ability of the telecommunications sector to build an inter-industry relationship with other sectors. A possible explanation for this result is the cellular uses which are much less related to business activities than that of fixed telephony dating back to the 1970s in Indonesia.
