Almost all studies carried out so far in China regarding debt examinations do not recognize difference among business sectors. China completed the second split share structure reform of listed firms by the end of 2007, which converted 97% non-tradable shares into tradable shares. However, there has been no study conducted to analyze whether determinants of debt have changed since the reform. Therefore, this study aims to find determinants of debt of listed firms in China by analyzing data after the completion of reform across sectors. Data sample used in this study includes all A-share listed firms in China from 2008 to 2012. After deleting missing values, there are in total 547 firms with 2,735 observations, which are taken as the initial full data sample. The method employed by the study is a panel data model, because it has the advantage of taking both cross-section and time series into consideration. In addition, a Hausman test is employed to identify whether a model with fixed effects or random effects should be used for analysis. The main findings are: (1) Total debt is mainly dominated by short-term debt, while long-term debt is lowly financed. During 2008 - 2012, total debt as well as long-term debts increase, but short-term debt decreases; (2) Determinants have different effects on long-term and short-term debts; (3) The effects of determinants are different across different sectors, indicating that specific sectorial factors are at work; (4) The debt decision tends to follow the static trade-off theory with consideration for effects of non-debt tax shield and profits. In general, both long-term and short-term debts are affected positively by profits at different levels. Firm size is the most important determinant and is positively related to long-term debt, while non-debt tax shield contributes negatively to short-term debt. This paper presents an in-depth understanding of debt decision in listed firms in China using a joint model to test the interaction between employee productivity and debt. It, therefore, provides a new perspective on investigations of debt decisions of firms across sectors.
