In this study we applied Two-Stage data envelopment analysis (Two-Stage DEA) approach to explore the profitability and marketability efficiency of solar cell industry in Taiwan and China suffering the financial tsunami in the period 2007-2010. We also utilizes Malmquist productivity index (MPI) to analyze overall total factor production change from 2007 to 2010 and furthermore propose the managerial decision-making matrix to provide suggestions in order for managers in inefficient solar cell industry to improve their operation performance. The Two-Stage DEA results indicate that approximately 43 percent of the solar cell companies have relative inefficiency in the profitability efficiency process and 74 percent of them are inefficient in the marketability efficiency process. Four years of Malmquist productivity Index annual results show that total factor production change (TFP) sharp declined by 60.3% which results from technical efficiency (TE) declined by 55%, and also scale efficiency (SE) declined 25%. Approximate 81% DMUs of solar cell industry is trend-down on scale efficiency, which means allocation of input sources is too much or some mistake had been made about decision-making. Ten solar cell companies are in zone 1 in the decision-making matrix represent leading position in the period 2007-2010. These ten solar cell companies can be benchmarks and may provide inefficient solar cell companies to learn with.
