基于综合数据的企业网络可控性分析
Controllability Analyses on Firm Networks Based on Comprehensive Data
摘要：
由于政府对企业进行刺激，并期望通过财政政策产生溢出效应，因此了解政府控制经济的有效性非常重要。为了阐明经济的可控性，我们研究了在日本详尽观察到的企业生产网络，以及应该使用控制理论直接或间接控制哪些企业。根据控制理论，我们可以将企业分为三种不同的类型：（a）应该被直接控制的企业;（b）应该被间接控制的企业;（c）两者都不是（普通）。由于在生产网络中有一个方向（供应商和客户），我们可以考虑对两个不同方向的控制：需求方和供应方。通过分析，我们得到以下结论：（1）每个行业都有不同的公司应直接或间接控制的份额。（2）产业的先进性，如第一产业或其他先进产业，在可控性上没有明显的差异;（3）如果我们按照资本规模的递减顺序裁剪网络，我们不会失去对需求侧和供给侧的控制效果。
英文摘要：
Since governments give stimulus to firms and expect the spillover effect by fiscal policies, it is important to know the effectiveness that they can control the economy. To clarify the controllability of the economy, we investigate a firm production network observed exhaustively in Japan and what firms should be directly or indirectly controlled by using control theory. By control theory, we can classify firms into three different types: (a) firms that should be directly controlled; (b) firms that should be indirectly controlled; (c) neither of them (ordinary). Since there is a direction (supplier and client) in the production network, we can consider controls of two different directions: demand and supply sides. As analyses results, we obtain the following results: (1) Each industry has diverse share of firms that should be controlled directly or indirectly. The configurations of the shares in industries are different between demand- and supply-sides; (2) Advancement of industries, such like, primary industries or other advanced industries, does not show apparent difference in controllability; (3) If we clip a network in descending order of capital size, we do not lose the control effect for both demand- and supply-sides.
