Can stable environmental protection officials’ tenure reduce illegal emissions?

Based on the day-night PM_2.5 difference of the nearest atmospheric monitoring points to measure whether there is illegal emission, this paper explores the impact of environmental protection officials' tenure (EPLT) on illegal emissions. The results show that there is a positive correlation between EPLT and illegal emissions. Stable EPLT can reduce illegal emissions by increasing environmental information disclosure and environmental subsidies. It can increase illegal emissions by weakening public pollution reporting and media supervision, environmental law enforcement and promoting corruption. In addition, EPLT can increase illegal emissions as EPLT is less than 3.55 years, while EPLT can increase illegal emissions as EPLT exceeds 6.21 years. Further, when mayor's tenure and EPLT are both stable, the promotion effect of EPLT on illegal emission is stronger. Stable company director's tenure can also aggravate the promotion effect of EPLT on illegal emissions.     

货币政策和银行风险承担：一种非线性关系

宽松的货币政策会通过估值、收入和现金流机制,追逐收益机制以及中央银行沟通和反应机制等渠道增加银行风险承担,通过风险转移机制降低银行风险承担,从而导致货币政策与银行风险承担之间可能存在复杂的非线性关系。本文使用面板阈值模型,基于我国银行业数据研究了货币政策对银行风险承担的影响,发现我国货币政策对银行风险承担的影响存在门限效应,即货币政策对银行风险承担的影响取决于货币政策基准利率偏离泰勒规则利率的程度。当这种偏离小于门限值时,宽松货币政策会增加银行风险承担;当这种偏离大于门限值时,宽松货币政策会降低银行风险承担。本文研究对更好地理解我国货币政策对银行风险承担及金融稳定的影响有一定参考意义。     

Threshold cointegration and nonlinear adjustment between goods and services inflation in the United States

In this paper, we model the long-run relationship between goods and services inflation for the United States over the period 1968:1–2003:3. Our empirical methodology makes use of recent developments on threshold cointegration that consider the possibility of a nonlinear relationship between the two inflation series. According to our results, the null hypothesis of linear cointegration would be rejected in favor of a two-regime threshold cointegration model. Consequently, we could expect a cointegrating relationship only when the divergence between services inflation and goods inflation is above the threshold point estimate.     

中国居民资产配置效率的门限效应研究:金融约束视角

本文基于金融约束视角,结合微观调查数据,并运用门限回归法和两阶段最小二乘法,对我国居民资产配置效率的门限效应问题进行研究。结果表明,从流动性约束、房产持有及商业资产持有三个角度分析居民面临的金融约束,居民资产配置效率的非对称门限效应在不同样本中都显著存在。居民持有资产的风险水平越高,带来的投资收益增量部分越低。同时,持有房产在缓解居民金融约束的同时,资产风险增加对于居民资产配置收益的促进作用仍然下降,受流动性约束影响低的居民以及持有商业资产的居民均能够获得更高的资产配置收益。在不改变金融约束的框架下,以商业性资产替代房产作为主要资产种类能够从微观层面增强经济稳定性,降低系统性金融风险,优化收入结构,提升资产配置效率。     

Urban-rural imbalance and Tourism-Led Growth in China

This study investigates the structural effect of tourism on alleviating the urban-rural dichotomy and the moderating effect of a dual urban-rural economic structure on Tourism-Led Growth (TLG). A theoretical framework followed by an empirical analysis based on relevant data from 31 Chinese provinces for the years 1998–2013 is presented. The main conclusions of the econometric analysis are that tourism growth can help reduce the urban-rural gap in China, but that the larger the gap between urban and rural economies, the less substantial is the influence of tourism on economic growth in China. Tourism may play an important role in Central-Western and Inland China, but their relatively greater urban-rural economic gap may threaten the positive effect of tourism.     

Risk-based decision analysis in support of precautionary policies

A decision-analytic model for avoiding a risky activity is presented. The model considers the benefit and cost of avoiding the activity, the probability that the activity is unsafe, and scientific tests or studies that could be conducted to revise the probability that the activity is unsafe. For a single decision maker, thresholds are identified for his or her current subjective probability that the activity is unsafe. These thresholds indicate whether the preferred course of action is avoiding the activity without further study, engaging in the activity without further study, or conducting a test or research programme to obtain additional information and following the result. When these thresholds are low, precautionary action is more likely to be warranted. When there are multiple stakeholders, differences in their perceptions of the benefit and cost of avoidance and differences in their perceptions of the accuracy of the additional information provided by the test or research programme combine to create differences in their decision thresholds. Thus, the model allows for the rational expression of differences among parties in a way that highlights disagreements and possible paths to conflict resolution. The model is illustrated with an application to phytosanitary standards in international trade and examined in terms of recent empirical research on lay perceptions of risks, benefits, and trust. Further research is suggested to improve the elicitation of model components, as a way of fostering the legitimate application of risk-based decision analysis in precautionary policy making.     

技术进步偏向、创新要素配置与经济韧性

基于2006—2020年中国内地31个省域面板数据,从影响传导机制、非线性特质角度探究技术进步偏向对经济韧性的影响效应。结果发现：(1)技术进步偏向对经济韧性具有显著正向影响,这一结论在稳健性与内生性检验中依然成立;(2)就作用机制而言,创新要素配置是影响技术进步偏向作用于经济韧性的重要机制;(3)门槛模型检验结果显示,技术进步偏向指数及其子维度与经济调整适应能力不存在非线性作用关系,但与经济创新转型能力具有非线性关系。因此,要合理引导技术发展方向,发挥技术进步偏向的积极作用;充分发挥“有效市场”和“有为政府”的合力作用,优化创新要素配置;以技术创新、理念革新与机制鼎新抵御潜在风险,增强经济韧性。     

FDI与OFDI溢出对高技术产业区域创新的门槛效应研究

选取2003-2016年省域高技术产业面板数据,以R&D人员投入为门槛变量,实证分析FDI与OFDI溢出对高技术产业区域创新的非线性影响。得出以下稳健性结论：FDI和OFDI溢出对高技术产业区域创新具有双门槛效应,FDI溢出呈现先升后降的特征,而OFDI溢出则呈现先降后升特征;R&D人员投入、R&D资本积累、城镇化水平有利于高技术产业区域创新,而金融成熟度未产生明显推动作用;政府支持可能对R&D人力投入较高省份产生抑制作用;2003-2016年跨越R&D人员投入中、高门槛的省份在不断增加。     

要素价格扭曲、行业异质性与R&D投入关系研究——来自中国制造业28个细分行业的证据

从中观视角研究要素价格扭曲对制造业R&D投入的影响及行业差异,厘清行业异质性背景下要素价格扭曲影响R&D投入的理论机制,运用制造业细分行业数据,结合非线性面板门槛模型进行深入分析。结果显示：要素价格扭曲对制造业R&D资本投入和R&D人力投入均均具有显著抑制效应,行业异质性因素在二者间发挥重要调节作用。进一步,运用面板门槛模型对行业异质性因素的作用进行探究。结果表明,行业特征因素如市场竞争、资本密集度、企业平均规模以及对外开放度在不同门槛值区间,要素价格扭曲对R&D投入的影响效应均存在显著差异。研究结论为全面深化市场化改革、提高要素资源配置效率、促进制造业自主创新转型升级,进而推动创新型国家建设具有一定启示意义。     

能源回弹效应下高碳产业低碳转型过程中的技术突变性

考虑能源回弹效应下,分析高碳产业低碳技术突变技术门槛,发现技术碳减排存在由量变到质变的门槛效应,另外还发现能源回弹对门槛效应具有显著影响。运用Hansen门限面板模型、结合CD生产函数的能源回弹模型发现：①不考虑能源回弹效应,高碳产业低碳化过程中的技术突变存在两个门槛;②考虑能源回弹作用,将减少为一个门槛,并且将延长高碳产业完成低碳技术突变所需时间。因此,为加快高碳产业低碳技术突变,有效减少碳排放,一方面应缓解能源回弹效应的影响,对能源回弹效应较大的高碳产业采取实时监控,对能源回弹较小的高碳产业采取定期检查和不定期抽检方式监控;货币政策、财政政策和产业政策相互配合,在高碳产业拉动经济增长的同时,最大限度控制能源回弹效应。另一方面,市场手段和政府职能双管齐下,协助企业低碳技术升级和设备改造,优化税收结构,弥补低碳技术升级导致的负外部性,完善高碳产业转移或市场退出机制。
