This thesis presented an empirical study exploring the performance of TFT-LCD industry through vertical integration in value chain. Statistical analysis methods were adopted to examine the performance of TFT-LCD industry. The following theories of the profit pool and DuPont financial analysis approach, supplemented by competitive strategies, vertical integration, value chain and profit pool theory literature, from the industry overview and key aspects of the value chain Profit distribution and changes in the degree of value chain integration impact on the profitability of panel makers. In this research, we focused on the different segment of the TFT-LCD value chain (color filters, polarizers, backlight module, driver IC and panel manufacturing). We used three financial performance indices of these companies between 2005 and 2009,namely ROE (Return on Equity; ROE), return on total assets (Return on Asset; ROA), operating margin (Return on Sales; ROS) such as most scholars commonly used financial indicators as measurement tools observe all aspects of the value chain profit changes. Finally from the perspective of profit pool and vertical integration strategies to examine whether TFT-LCD panel manufacturers could use an integration strategy as a way to improve their performance on operating profit margin and lower the risk. The results are as follows: the value of different levels of vertical integration, panel makers will do the performance of the operating profit margin have different effects, with the active dwell Taiwan¡¦s TFT-LCD industry up the value chain integration, is indeed closer to or exceed the Korea TFT-LCD maker, but with the TV panel sales with a gradual increase in the proportion of the panel sales , sales channel became a key factor in whether or not profitable. Therefore, the panel makers may be able to consider more closer cooperation with the player of home appliance industry and downstream continuing down the value chain to make the direction of integration efforts.

The study focus on the mapping ofthe value chain starting at one ofthe 21 distributors ofLP Gas and their retails in a specific sales area. For the fixed costs and expenses mapping ofthe distributor and their retails the Activiy Based Costs -ABC were used. For the profit map the earnings before interest, taxes, depreciation and amortization -Ebitda were used. After the mapping the maio variables that explain the Ebitda ofthe distributor and their retails were identified. Furthermore, to identify the variables two regressions were made to explain the unitary profit (R$/cylinders) ofthe distributor and their more than 500 retails in a specific sales area. The results show an estimate of how the contribution margin, expenses and profits in the distribution chain of the domestic LP Gas in Brazil were divided between the distributors and retail in the year of 2007. Moreover, the variables that impact in the Ebitda formation were explained for the distributor and the retails in the case study. Furthermore, the dissertation discusses the potential of the profit pool map in the value chain during the text and conclusion. / A dissertação é um estudo de caso que tem como objetivo mapear a margem de contribuição, gastos e lucros na cadeia de distribuição do gás de cozinhas no Brasil. O trabalho focaliza o mapeamento da cadeia de valor a partir de uma das 21 distribuidoras de Gás LP e suas revendas em uma de suas áreas de atuação. Para o mapeamento dos custos e despesas fixos da distribuidora e de seus revendores foi utilizado o custeio baseado em atividade - ABC. Para o mapeamento do lucro foi utilizado o lucro antes dos juros, impostos, depreciação e amortização - Ebitda. Após o mapeamento buscou-se identificar as principais variáveis que explicam a atual configuração Ebitda da distribuidora e de suas revendas. Para isso foram geradas regressões de dados para entender o lucro unitário (reais por botijão de gás) da distribuidora e de suas mais de 500 revendas em uma das áreas de atuação. O resultado mostra uma estimativa de como a margem de contribuição, gastos e lucros na cadeia de distribuição do gás de cozinha no Brasil para o ano de 2007 se dividem entre as distribuidoras e revendedores de Gás LP domiciliar em termos percentual e unitário. Também foram explicadas quais as variáveis que mais impactam no Ebitda da distribuidora e revendas do estudo de caso. Por fim, o trabalho discute o potencial da metodologia de análise de mapeamento através do profit pool na cadeia de valor da indústria ao longo do texto e na conclusão do trabalho.
