This thesis is one of the first attempts to present a study of the "Industrial Development of the Lebanon". The aim therefore was to cover the widest possible scope rather than to deal with any particular industry or its problems. It is intended that this thesis should serve as a basis for further more specific investigations. The purpose of this study is: - To give a statistical measurement of existing Lebanese industries, - To examine their problems and prospects. - To suggest some solutions to these problems. - To study prospects for new industries.
