Abstract: In perspective of maximizing the economic growth rate, this article examines the optimal size of China’s fiscal expenditure with theoretical and empirical methods. Based on exploring the Congested Public Goods Model and the Pure Public Goods Model, we estimate that during the year of 1978-2006 the optimal size of China’s fiscal expenditure is about 20-25% of GDP. According to this criterion, China's fiscal spending policies can be divided into three development stages: (1) the higher size phase (1978-1992); (2) the lower size phase (1993-2000); (3) the optimal size phase (2001-2006)

Abstract: With the datum of output, energy consumptions and environment pollutions of 36 industries of HeBei Province during the period of 2005-2007, we first calculated the marginal values of GDP contributions, energy consumptions and environment damages each industry played on the whole provincial economy. Compared with the average values, the industries were further divided into four groups with the method of Four Quadrants, which are the ones of (High-Growth-Contribution, High-Energy-Consumption or High-Pollution), (Low-Growth-Contribution, High-Energy-Consumption or High-Pollution)), (Low-Growth –Contribution , Low-Energy-Consumption or Low-Pollution), (High-Growth–Contribution , Low-Energy-Consumption or Low-Pollution). Based on this division, we put forward the suggestions of structural adjustment for each group of industries in views of sustainable development.

Abstract: From the perspective of maximizing the economic growth rate, this paper examined the optimal size of China’s fiscal expenditure with theoretical and empirical methods. First, the paper established a Pure Public Goods Model, based on which it further estimated that during the period of 1978-2006, China’s optimal size of fiscal expenditure is about 21.82-27.28 percent of GDP. Judging by this optimal criterion, it finally divided China's policy development into three stages: (1) the higher-size stage (1978-1992); (2) the lower-size stage (1993-1999); (3) the optimal-size stage (2000-2006)
