经济密度、人口规模与环境污染——基于城市面板数据的实证分析

选取2005-2016年285个地级及以上城市数据,利用静态和动态短面板模型分析经济密度和人口规模对环境污染的影响,分析表明:经济密度与环境污染之间存在“倒U型”关系,人口规模扩大会抑制污染物排放;不同等级城市经济密度、不同规模城市人口对环境污染的影响方向一致,但影响程度有所差异;前期污染排放对当期具有正向影响,环境污染物排放存在路径依赖;经济发展水平、工业产值占比和对外开放也是影响污染物排放的重要因素,但各指标对三类污染物排放的影响方向和影响程度存在差异。据此认为,在综合考虑城市具体空间区位条件下,人口适度集聚,提高城市经济密度,优化产业结构以及加强环境监管是环境治理的重要方向。     

Give mind to the gap: Measuring gender differences in financial knowledge

Prior research consistently finds a gender gap in financial knowledge where males appear to outperform females. Despite the wealth of studies attempting to explain this gap, none have considered whether the gender gap may be a product of measurement method. This study re-examines the gender gap with item response theory (IRT) which can account for guessing behavior and differential item functioning. Survey data on 184,869 individuals from 39 countries and territories is analyzed. Results show that when IRT is employed, a gender gap exists in only 54% of the sample. In contrast, when a conventional measurement approach is used, there is a gender gap in financial knowledge in 81% of the sample. These results reveal that prior measurements may underestimate women's financial knowledge and inflate the gender gap.     

An item response theory approach to constructing and evaluating brief and in-depth financial literacy scales

We applied item response theory (IRT) to construct and evaluate new brief and in-depth financial literacy scales. A survey of a UK adult sample (N = 589) included 50 questions to assess knowledge about managing financial resources and competence in using personal finance-related information—including five widely used items, on interest rates, inflation, investment diversification, mortgages and bonds. IRT applied to a scale of these items identified some limitations, overcome via further iterations to construct a new brief scale with sound psychometric properties. IRT was then applied iteratively to our pool, resulting in an in-depth, 20-item scale, also psychometrically sound, covering four broad financial domains: everyday money transactions; the concept of money; borrowing; and saving and investment. Parallel 10-item sub-scales were also evaluated. The validity of the new scales was demonstrated by regression analyses which found that, controlling for demographic variables, financial literacy predicted key indicators of financial well-being.     

Don't call us,we'll call you: Considering cognitive and physical effort in designing effective response systems to manage extended in-process wait

People must often wait for days or weeks to receive test results, price quotes, products, etc. Service providers may manage user experience during such in-process waits using notification systems that inform users when a response is available or inquiry systems that require users to inquire about response availability, thereby imposing prospective memory requirements on users. Based on the prospective memory and wait time literature, we make predictions regarding how response system (notification vs. inquiry) moderates the effects of waits that are shorter or longer than the provider promised on user evaluation of the wait. We find that users of a notification system evaluate a wait more positively and are less sensitive to deviations of actual from promised wait time than are users of an inquiry system. This advantage was more pronounced for a wait that was longer (vs. shorter) than promised. These effects of system and expectation on evaluation were fully mediated by their impact on the cognitive and physical effort of navigating the system. Finally, a week after having experienced a wait, users of an inquiry system who had waited longer (vs. shorter) than promised cooperated less on a follow-up task, highlighting another downside of using an inquiry system.     

Net-zero emission targets and the role of managerial environmental awareness,customer pressure,and regulatory control toward environmental performance

To avoid the worst effects of global warming, countries agreed to limit warming below 2.0°C and ideally to 1.5°C preindustrial level. This requires countries to drop half of their greenhouse gas emission by 2030 and reach net-zero emission by 2050. In this regard, current study explores the role of green production as a mediator in the impact of managerial environmental awareness, customer pressure, and regulatory control on environmental performance. The data collected from 381 managers was analyzed using structural equation modeling (SEM) technique. Results indicate that customer pressure, regulatory control, and managerial environmental awareness play a pivotal role toward green production, whereas only managerial environmental awareness among them directly influences environmental performance. Green production fully mediates the relationship from customer pressure and regulatory control to environmental performance. However, it partially mediates the relation between managerial environmental awareness and environmental performance. Similarly, the importance of green production for environmental performance is highlighted.

［目的］为改变乡村旅游非生态化发展的现状，全面实现乡村振兴。［方法］结合使用文献综述法和实地调研法，基于环境正义理论，将环境问题与社会正义结合起来分析乡村旅游环境问题产生的根源。［结果］一直以来，乡村旅游作为实现乡村振兴的重要方式都过于追求经济效益，而忽视了给乡村旅游地及其周边区域带来的环境污染和生态破坏，造成乡村旅游种际环境非正义和人际环境非正义。［结论］代内人际环境正义的实现是解决乡村旅游环境问题的关键，确保未来乡村旅游发展的环境正义导向和矫正当前存在的环境非正义是必须同时兼顾的两个方面。实现乡村旅游环境正义，一方面应增强主体的环境正义意识、构建公正的环境相关制度以确保乡村旅游未来发展的环境公正导向，另一方面应探索建立乡村旅游生态补偿制度对已经造成或现阶段无法避免的环境非正义结果进行矫正，实现补偿正义。     

Socio-emotional wealth and corporate responses to environmental hostility: Are family firms more stakeholder oriented?

Do family firms care more for different stakeholders than nonfamily firms when operating in a hostile business environment? This study addresses this question and fills the existing void in family business research. It shows that family-controlled firms adopt corporate social responsibility strategies and balance the demands of internal and external interest groups to preserve their socio-emotional wealth while facing fierce competition, resource scarcity, and penurious economic conditions. More specifically, our analysis of an international sample of 956 listed firms from 2006 to 2014 reveals that family firms show a higher level of corporate social responsibility (CSR) performance and better stakeholder orientation than nonfamily firms. Our findings are useful for managers, policymakers, and responsible investors.     

The effect of environmental regulations,top management commitment,and organizational learning on green product innovation: Evidence from automobile industry

This paper proposes and empirically examines a model to investigate the effect of environmental regulations, top management commitment (TMCO) and organizational learning toward green product innovation (GPI). The proposed theoretical model, grounded in dynamic capabilities view (DCV) and upper echelons theory, is analyzed by Partial least squares (PLS) method using the data from Indian automotive manufacturing firms. The findings indicate the importance of TMCO and organizational learning for implementing GPI (in response to regulations), and achieve desired performance. Further, organizational learning fully mediates between commitment of top management and GPI. The findings can be useful for managers in automotive manufacturing firms who are interested toward implementing GPI. The paper contributes to green innovation literature by empirically examining the role of TMCO and organizational learning for GPI.     

Productivity impact of drought tolerant maize varieties under rainfall stress in Malawi: A continuous treatment approach

Drought tolerant (DT) maize varieties have received massive support in sub‐Saharan Africa because of their potential to protect smallholder farmers against drought‐related maize yield losses. Using four waves of household farm panel data from six districts in Malawi, we examine the impact heterogeneity of this technology on maize productivity using a continuous treatment approach. We find strong evidence of positive correlation between maize yield and adoption of DT maize varieties. On average, an increase by one hectare in the area allocated to DT varieties increases maize yield by 547 Kg/ha representing a 44% increase from the average maize yield of 1,254 Kg/ha for our sample. Our findings give evidence that DT maize technology has potential to protect smallholder farmers against drought‐related production losses. Policies that promote increased allocation of maize area to DT maize hold potential to enhance food security. Smallholder farmers especially in drought‐prone areas should be encouraged to allocate at least one‐third of the maize plot to DT varieties while breeders continue with the efforts of breeding a DT variety that is not only drought tolerant but also adapted to all weather conditions. More importantly, the government should ensure provision of timely ex ante weather information to guide farmers on decision‐making with respect to maize varietal choices.     

Internal green integration and environmental performance: The predictive power of proactive environmental strategy,greening the supplier,and environmental collaboration with the supplier

The effect of proactive environmental strategies (PES) on corporate performance has been debated extensively among academics; however, the significance of the pathway of those strategies—internal green integration (IGI) through greening the supplier (GTS) and environmental collaboration with suppliers (ECS)—remains undecided. This study examines environmental performance (EP) through GTS, IGI, and ECS. It also examines the direct link between PES and IGI. A conceptual framework was designed following a rigorous review of the literature. A survey questionnaire was used to collect cross-sectional data from a random sample of manufacturing firms, obtaining 196 usable samples. Using AMOS, the structural equal modeling found a positive and significant impact of PES on IGI. Significant predictors of EP were GTS, IGI, and ECS. The findings of the study can provide managers with guidelines for dealing with business and environmental concerns. They can also contribute to creating strategies for environmental protection and management and reducing adverse effects on the environment. Finally, by examining the direct links between GTS, ECS, and EP, particularly in a developing context, the study may contribute to the literature of environmental policy.
