The main sectors contributing to economic growth are building and construction, infrastructure development, manufacturing, transport and services, and tourism particularly from emerging markets; agriculture, and wholesale and retail.This sector is mainly agro based at the moment and plays an important role in adding value to agricultural output by providing forward and backward linkages with agricultural sector. However, there is a shift to export oriented manufacturing as the main thrust of Tanzania's industrial policy since the country aims to raise the share of products in the regional market from 7% to 15 % and develop niche products for existing and new markets. Mkinga is promoting development of Special Economic Zones (MSEZONE), Industrial Parks, Industrial Clusters, promotion of small and medium scale manufacturing firms, development of niche products, commercialization of research and development results.
Transport and communications are worth approximately 11 percent of GDP. Mkinga envisages a massive upgrading and extension of the country's infrastructure. In this regard, the country has highlighted a number of infrastructure projects that present significant opportunities for investors in the coming years.It is important to note that while the Government has put forward plans on how it would like to develop infrastructure, it is equally open to ideas and proposals from potential investors. Redevelopment of the Estern Corridor Development of a commuter railways system around Tanzania Building of a standard gauge line to replace the current Tanzania-Uganda railway Design and Construction of a new terminal at Tanga Development of a new corridor from Tanga to EAC Investments into these projects can either be through direct investments or through public private partnerships.
The size of the local ICT market is estimated at US$ 500 million and it is of note that companies such as Spanco, followed Airtel into Tanzania to continue servicing them. These companies are expected to expand into the region , given Tanzania's its relative sophistication compared to neighbouring markets, and in order to service clients' expansion plans into the EAC and beyond.
Mkinga has a well-developed building and construction industry with quality engineering, building and architectural design services being readily available. This industry is currently on an upward trend following re-habilitation and reconstruction of roads and bridges under the Tanzania Urban Transport Infrastructure Program.
