This paper begins by offering a general introduction to the book, goes on to conduct a detailed chapter-by-chapter review and then ends by stressing its three merits and demerits, namely: On the one hand, this book successfully connects theory with empirical research; It has largely avoided drawing simplistic conclusions; It has wide social implications. However, on the other, this monograph is not immune to gender bias and its conclusions are limited to a certain social sphere.展开更多

In 2005,China's total tax revenue topped 3.0866 trillion Yuan (excluding tariffs and agricultural taxes), up 20%and 514.8 billion Yuan over 2004 and exceeding 3 trillion Yuan for the first time. During the 10th five-year plan period,the total tax revenue remitted into the state coffer amounts to 10.9217 trillion Yuan, with an average annual increase of 19.5%; and the revenue in the fifth year more than doubles that in the first year. The fast and steady growth of the tax revenue in pace with the economic growth has greatly enhanced the country's financial strength and provided solid financial guarantee for the country's efforts to build a well-off society in an all-round way.……展开更多
