Research Analysis of Policy Process in Legislation for the Resuscitation of Social System

1.土地利用与环境融合领域的建设立法方案在提炼现行城市规划与建筑规制、租赁住房、司法止赎、景观、城市环境等法律体系存在的问题后，构建了解决这些问题的具体立法方案。并运用科斯定理等法学和经济学的工具对其进行了分析，验证了其有效性。基于土地利用与交通综合模型的法律修订影响定量分析运用东京大都市区（1个首都、3个县和茨城县南部）的土地利用与交通综合模型，在道路收费、城市规划与建筑法规、环境与景观立法等方面的法律修订假设下，对交通流、环境影响和城市结构的影响进行了估算。容积率（容积率）奖金将提高20%，容积率上限将提高……东京23区商圈的管制力度加大，将使23区外来劳动力增加约140万人。与此相关的是，6号环路与2号环路之间区域的汽车交通流量增长了5.5%，2号环路以内区域的汽车交通流量增长了2.1%。此外,后环内路八号收费区域设立19个区域内,如果道路收费被引入,这费用统一人数200 (a)的车辆流量的外环路八号区,或(b)的车辆运行通过19区环形方向的边界或向中心,如果这三个环外环道路路八号,6号环线至2号环线区间的汽车交通流量将下降3%，2.3号环线以内的汽车交通流量增幅将控制在1.2%以内。▽法律修订案的综合成本效益分析=如果规定上限提高20%，每年将增加4917亿日元的办公室租金收入。如果实行道路收费制度，建设8号环线以外的3条环线，每年因交通堵塞造成的社会损失将减少到713亿日元。此外，还发展了估算因环境和景观恶化而造成的社会成本的措施以及创建法律修订给社会带来影响的资产负债表的方法。科学方法论在立法上的推广基于上述结果，发展了“假设-验证”型立法的普遍方法论。少

1.Building Legislation Scheme on the Fusion Domain of Land Use and EnvironmentAfter extracting the problems of the current system for the law on city planning and building regulation, rental housing, judicial foreclosure, landscape, urban environment, etc., the concrete legislation scheme for solving them has been built. Moreover, after analysing it applying the tools of law and economics, such as the Coase theorem, validity of it has been verified.2.Quantitative Analysis of Legal Revision Influence by the Integrated Model on Land Use and TransportationApplying the integrated model on land Use and transportation for the Tokyo metropolitan area (1 capital, 3 prefectures and southern Ibaraki), the influence has been estimated on traffic flow, environmental impact, and urban structure, on the supposition of legal revision concerning road pricing, city planning & building regulation, and environment & landscape legislation. FAR(floor area ratio) bonus increasing by 20% the ceiling of FAR r … More egulation in the business districts of Tokyo's 23 Wards will increase the work force by about 1,400,000 in the 23 wards in total by inflow from outside the area. In relation with this, the amount of automobile traffic flow increases by 5.5% in the area between Ring Road No.6 and Ring Road No.2, and 2.1% in the area within Ring Road No.2. Furthermore, after making the area within the Ring Road No.8 the fee collection area and setting up 19 zones within it, if the road pricing be introduced, which charges the unified toll of 200 on (a) the vehicles which flow from the outside of the Ring Road No.8 into the zones, or (b) the vehicles which run passing through the boundary of 19 zones in the annular direction or towards the center, and if the three ring roads outside the Ring Road No.8 be constructed, the amount of automobile traffic flow will decrease by 3% in the area between Ring Road No.6 and Ring Road No.2 and will stop at 1.2% of increase in the area within Ring Road No.2.3.Synthetic Cost-benefit Analysis by Legal RevisionFAR bonus increasing by 20% the ceiling of regulation will increase the office rent income by 491,700 million yen per year. The social loss by traffic jam will stop at 71,300 million yen per year, if road pricing be introduced, and the three ring roads outside the Ring Road No.8 be constructed. In addition, the measures of estimating social cost due to the environmental and landscape deterioration and the methodology which creates the balance sheet of the influence which legal revision brings to society have been developed.4.Generalization of scientific methodology on legislationBased on the above result, the universal methodology applied in legislation of "hypothesis-verification" type has been developed.
