In this thesis, the author focuses on three objectives. They are (i) to determine market structure and competitive nature of the music industry, (ii) to determine factors affecting its demand and (iii) to analyze conjectural variations of the music industry.The author applied oligopoly theory in order to determine market structure of music industry. The analysis of possible factors affecting demand within the music industry by using the “Two - Stage Least Squares”. In addition, an econometric model is formulated to examine conjectural variations. These analyses are capitalized on data from the year 2003 through 2007.Results indicated that market structure of the music industry is oligopoly. Each firm prefers non price competition to price competition. The significant factors of demand are price and national income. And the reasonable demand function is logarithm. The analysis of conjectural variations illustrates that each firm concerns about the conjectural variation from other firm. In addition, firms also exhibit a pattern of implicit collusion.
