Based on thoroughly research, the author draws some following conclusions:(1) the origin of new bilateralism in Asia-Pacific is that each country altered its trade policy to maximize its gains from trade when they faced common external shocks, which is not only to satisfy the restrains of internationally political and economic environments but also to help each government to balance internal political economy when they implement trade liberalization;(2) it has been a common trade policy for each country in Asia-Pacific to set up bilateral trade agreements as soon as possible and as much as possible to obtain hub position in the network of bilateralism;(3) with the inevitable spread of bilateralism, China, as a developing large trade economy, should take first start to guide a favorable process of regional economic integration depending on its booming economy, large domestic market, cheap labor price and abundant natural resources in aim to get much more benefits and advantages.

经过笔者研究，《亚太新双边主义的政治经济学分析》一文得到如下结论：其一，亚太新双边主义的兴起是20世纪末亚太地区各经济体在面临外部冲击的情况下，权衡内部政治经济，选择在当前国际政治经济环境的约束下能够最大化自身利益的贸易政策的必然结果；其二，尽可能快尽可能多地签订双边自由贸易协定，谋求新双边主义中的"轮轴国"地位已经成为各经济体今后较长时间内对外贸易政策的共识；其三，区域经济一体化中的新双边主义趋势已经不可避免，中国作为发展中的贸易大国，应该凭借不断增长的经济、广阔的国内市场、廉价的国内劳动力和丰富的国内资源，发挥先发优势，谋求以我为主的区域经济一体化进程，争取有利的战略地位和更多的利益。

电路 2 电路或电网络由以某种方式连接的电阻器，电感器和电容器等元件组成。如果网络不包含能源，如电池或发电机，那么就被称作无源网络。换句话说，如果存在一个或多个能源，那么组合的结果为有源网络。在研究电网络的特性时，我们感兴趣的是确定电路中的电压和电流。因为网络由无源电路元件组成，所以必须首先定义这些元件的电特性。就电阻来说，电压-电流的关系由欧姆定律给出，欧姆定律指出：电阻两端的电压等于电阻上流过的电流乘以电阻值。在数学上表达为： u=iR (1-1A-1)式中 u=电压，伏特；i =电流，安培；R =电阻，欧姆。纯电感电压由法拉第定律定义，法拉第定律指出：电感两端的电压正比于流过电感的电流随时间的变化率。因此可得到：U=Ldi/dt 式中 di/dt =电流变化率，安培/秒； L =感应系数，享利。电容两端建立的电压正比于电容两极板上积累的电荷 q 。因为电荷的积累可表示为电荷增量 dq 的和或积分，因此得到的等式为 u=，式中电容量 C 是与电压和电荷相关的比例常数。由定义可知，电流等于电荷随时间的变化率，可表示为 i = dq/dt。因此电荷增量 dq 等于电流乘以相应的时间增量，或 dq = i dt，那么等式(1-1A-3)可写为式中 C =电容量，法拉。
