PPP政策扩散影响因素研究——基于省级政府数据的事件史分析

基于政策扩散理论,收集整理2014~2021年间中国31个省、直辖市及自治区的面板数据,从政策主体、政策客体及政策环境3个维度提出研究假设,采用事件史分析法对我国省级政府PPP政策扩散影响因素进行实证研究。结果表明:政策主体、政策客体及政策环境因素都会影响到省级政府PPP政策扩散,其中政府财政能力、地区人口规模、私营部门数量、学习机制及强制机制是影响省级政府PPP政策采纳的重要因素。     

State-sponsored and spontaneous urbanization in Fujian province of China, 1982–2010

This paper examines unbalanced urbanization process in Fujian province from 1982 to 2010 from the perspective of dual-track urbanization. The analysis is mainly based on 67 county-level units. The spontaneous track of urbanization is a new process of urbanization in China emerged in the reform period. It plays an important role in linking urban and rural areas but also creates problems of rural-urban integration and social cohesion. This paper examines the relative roles of spontaneous and state-sponsored urbanization and their impacts on the spatial pattern and structure of urbanization in Fujian. It is found that rural to urban migration plays the most significant role while state-sponsored urbanization and rural urbanization play equal roles in the process of urbanization. There was a significant shift of state-sponsored urbanization from county-level cities and counties to urban areas of central cities, Fuzhou and Xiamen, and from inland area to coastal area after 1990. There have also been significant shift and growth of temporary population towards the central cities in the reform period. The shift from small towns to large urban areas is clear in both tracks of urbanization.     

基于前景理论的建筑行业合谋监管博弈分析

建筑行业已经成为我国政企合谋与腐败的重灾区之一。为研究建筑行业合谋行为的防范机制,基于前景理论构建国家、行政主管部门及建筑企业的三方收益感知矩阵,从而进行合谋监管的博弈分析,探寻合谋的条件及影响因素,并对影响因素进行敏感性分析。结果表明若不考虑心理因素尤其是损失规避的影响会对合谋监管策略产生较大偏差。合谋监管应从两方面进行:一是保证最佳的打击合谋事件的力度;二是通过制度设计降低合谋方策略均衡的监管概率,其具体的影响参数包括名誉损失率、惩罚与收益的比值、成本与收益之比以及合谋方心理因素。针对识别出的关键变量,对抑制合谋行为提出相关的对策建议。     

扬子江城市群工业能源碳排放与经济增长脱钩水平及驱动因素

扬子江城市群地处长江经济带的下游重要门户地区,是江苏省“1+3”重点功能区发展的龙头引擎,打造扬子江城市群的绿色生态走廊对建设“强富美高”新江苏和落实长江大保护均具有重要战略意义。论文聚焦扬子江城市群工业能源碳排放脱钩及其驱动因素分析,研究得出：1）扬子江城市群整体工业碳排放量呈现波动上升的变化趋势,其中南京市和苏州市的碳排放增量明显大于其他城市;2）扬子江城市群工业能源碳排放脱钩大致经历了扩张连接、强脱钩以及弱脱钩3个阶段,整体上脱钩水平逐渐提高,但稳定性不高,各城市工业能源碳排放脱钩水平差异较大,但在逐步优化中;3）从驱动因素看,碳排放强度效应和能源强度效应对脱钩水平有促进作用,工业经济规模效应、区域经济比重和能源结构则相反。基于此,论文提出加强低碳城市试点建设、探索构建全域碳权交易市场、调整优化能源结构、推动科技创新等建议,以促进扬子江城市群工业建设高质量发展。     

水污染变动的时空特征及其经济驱动因素——以江苏省为例

基于2007—2014年江苏省各地区的经济与水污染数据,运用全局Moran’s I 指数、LMDI指数及LISA聚集图,将水污染的经济驱动因素分解为规模效应、结构效应、科技消费效应及技术污染效应,探究江苏省水污染的时空变动特征。结果表明,GDP与水污染总量在空间上呈正相关关系,2007—2014年相关性先增后减。在时间维度上,规模效应及科技消费效应的变化增加了江苏省各地区的水污染效应,结构效应及技术污染效应的变化则减少了水污染效应;在空间维度上,规模效应及科技消费效应存在低值聚集效应,结构效应不存在显著的空间聚集效应,技术污染效应存在高值聚集效应及高低值聚集效应;江苏省水污染重心为119.6395°E—119.6892°E,32.1038°N—32.2075°N的区域,水污染重心自南向北转移,在东西方向上选择性移动。

A model of unsafe behavior in coal mines based on game theory

Behavior choice, coal mine monitoring, and control intensity are combined in a general mathematical model established from the perspective of a behavioral game. A case study is provided with effective conditions of monitoring provided. This paper defines the expected value difference of control return and behavior cost difference and discusses the measurement and optimization of variable indexes, including the monitoring intensity and costs of control. The results imply that the control of unsafe behavior can be more effective when monitoring and control of coal mines are both improved. Monitoring will be useful when the rewards for displaying safe behavior, and the monitoring of unsafe behavior, are improved to a high level.     

Further results on stochastic admissibility for singular Markov jump systems using a dissipative constrained condition

In this paper, the stochastic admissibility analysis problem is investigated for a class of singular Markov jump delayed systems (SMJDSs). The purpose is to establish some conditions such that the SMJDSs are stochastically admissible and strictly (X, Y, Z)-μ-dissipative. A mode-dependent Lyapunov functional and some novel inequalities are proposed for the considered SMJDSs. Based on these, some new stochastic admissibility conditions are established. In comparison with the existing results, the advantage of the obtained conditions lies in the fact that they are not only less conservatism but also more general. Four numerical examples borrowed from some existing papers are given to demonstrate the effectiveness and the reduced conservatism of the presented method.
