Solid theoretical knowledge in the fields of mathematics, economics, financial investment, etc., and advocating the realistic and hard-working fashion of "sitting on the bench for ten years".

2. Literature basis

I keep up with the academic frontiers at home and abroad, and subscribe for a long time at my own expense: economic research, economist, economic science, economic trend, quantitative economy, technical and economic research, financial research, international financial research, investment research, finance and trade economy, management world, China management science magazine and operational research magazine. And keep up with the academic trends led by English academic journals such as Journal of Political Economy, American Economic Review and Econometrics.

3. Computer Foundation

Fast five-stroke input. Familiar with office software. Skillfully use Mathematica and other mathematics, statistical software and drawing software and apply them to the writing of academic papers.

4. Mathematics foundation

Consider four reasons: (1) Mathematical skills are increasingly widely used in economics, management science and financial investment; (2) I didn't specialize in mathematics when I was an undergraduate; (3) "University is a place to learn advanced knowledge"; (4) The logical power of mathematical science itself and the concise charm of its formal language. Therefore, Liu Liang attaches great importance to mathematics. Since the mid-1990s, Liu Liang has learned a lot of mathematical literature by himself with rare hard work, and gained a preliminary understanding of almost all branches of mathematics. The materials that must be read almost every day are: Dictionary of Mathematics (six volumes, including more than 100 branches of modern mathematics), Encyclopedia of Mathematics of the Soviet Union (five volumes), Mathematical Volume of Encyclopedia of China, Handbook of Modern Mathematics edited by Xu Lizhi (five volumes) and New palgrave Dictionary of Economics (four volumes).
