参与和治理:中国社会安全网建设的战略选择

中国正处在社会经济转型时期,在此期间,社会安全网的建设完善与否不仅是保证经济持续增长的内在要求。更是保证社会稳定的关键。分析中国社会安全网的建设过程,评估社会安全网的状况,本文认为,中国社会安全网的未来走向或者战略选择应该以政府为主导力量,通过多元主体的互动逐步迈向善治,实现从政府管理到治理的转变,建立责任分担的社会风险防御机制,提升弱势群体的社会参与机会与能力,消除社会隔阂、实现社会整合。     

西方经济学范式的转换和发展———从经济学方法论的视角分析

文章从经济学方法论的视角研究西方经济学的范式及其转换。首先阐述了经济学范式的内涵,接着阐明了经济学范式革命的实质就是范式转换,以及范式转换的多样化表现形式。在此基础上,分别详述了范式演进、范式综合、范式偏离、范式复归、范式交融和范式变异的例证及其各自的特点,从而通过剖析经济学范式的转换揭示西方经济学演变和发展的轨迹。

“双碳”新格局下企业绿色技术创新对其 ESG 绩效的影响及其路径研究

2030年前实现“碳达峰”,2060年前实现“碳中和”是中国对世界的郑重承诺,表现出了中国的担当精神。在“双碳”新格局下,局限于企业的经济表现的传统绩效衡量办法不足以满足现代化投资的需要,综合评价企业环境、社会和管理三个方面的ESG绩效体现出巨大优势。各类绿色政策的出台引导企业走向绿色技术创新,那么绿色技术创新会对企业ESG绩效产生什么影响？本文基于2011—2020年的A股上市公司数据,采用固定效应模型进行实证检验。研究表明,企业绿色技术创新会对企业ESG绩效产生促进作用;实用新型绿色技术创新对ESG的促进作用大于发明型绿色技术创新的促进作用;并深入研究发现,先通过绿色技术创新再提升市场竞争力最后实现企业ESG绩效的优化是最重要的影响路径。     

产业联系与北京优势产业及其演变

根据经济基础理论,城市经济增长源于城市外部需求.一个城市的比较优势体现在服务于外部市场的产业中.论文基于北京市投入-产出表,依据产业净流出,分析了北京市产业的比较优势及其变化.过去15年来,北京的劳动密集型和原料型制造业的优势逐渐丧失,以电子通信设备、化学工业和机械设备制造业为代表的资本和技术密集型产业正成为优势产业;服务业中,传统服务业从20世纪80年代的优势地位退居劣势地位,取而代之的是知识密集型的生产者服务业,如金融业、软件和计算机服务业、信息传输服务业、广告业、房地产开发业、商务服务、科技交流和推广服务业等.产业联系是北京产业比较优势的显著影响因素,资本、知识和技术是北京市产业比较优势的投入支撑.     

计算机网络发展存在的威胁及其解决策略

当前,在随着计算机网络时代不断的进步发展,而全球市场的信息化管理也已经逐渐成为发展的主要趋势,然而,由于计算机网络是一种联结形式的网络开放式、多样性,具有终端分布的不均匀性以及互连性等一些主要特征,从而就会导致网络极易受到威胁,因此,对于网络信息的保密性和安全性则是非常重要的一个问题。不管是在广域网中还是局域网中,人为因素或者是自然因素都会存在一定的潜在威胁。对此,为了计算机网络会有一个良好的发展空间就必须要提高它的安全管理措施,以全方位、多角度的对待各种潜在的威胁,从而保证网络信息具有保密性以及完整性。     

Household tax evasion

Household members share public goods and make intra-household transfers. We show how these features of the household interact with the tax evasion decision, and identify the dimensions in which household evasion differs from individual evasion. In the model we present two members of a household choose how much to contribute to a household public good and how much self-employment income to evade. We are interested in how different evasion possibilities interact with the contribution decisions to the household public good and the role of income transfers within the household. We show the household evasion decision differs from the individual decision because it affects the outcome of the household contribution game. When household members are taxed as individuals neutrality applies when choices are not constrained. If the evasion level of one household member is constrained then an income transfer can generate a Pareto improvement. When the household members are jointly taxed there is a couple constraint on strategies and corner solutions can emerge.     

Net primary production and gross domestic product in China derived from satellite imagery

Since the 1980s Chinese economic reform has greatly accelerated its economic growth while in contrast China's environment is increasingly degraded. The Chinese government has recognized that environmental protection and sustainable economic development can promote mutual and sustainable co-development of the economy and the environment as a basic national principle. This paper examines the interactions between economic development and environmental change in China that were compared and analyzed for the years 1996 and 2000. Net primary production (NPP) was selected as a proxy evaluator of ecosystems and gross domestic product (GDP) was chosen as a proxy evaluator of economic development. An NPP change map was produced with Advanced Very High Resolution Radiometer (AVHRR) summed annual NPP imagery products. The Defense Meteorological Satellite Program's Operational Linescan System (DMSP/OLS) nighttime imagery was used to produce a Chinese GDP change map. An integrated map was produced to exhibit the combined changes of NPP and GDP. This map showed that in the regions with increased GDP, NPP decreased but the regions with no GDP change were smaller in area for NPP increase while larger in area for NPP decrease. The changing pattern of NPP varied with the developing level of GDP at province level. A province's development of GDP is controlled by its accessibility to natural resources. Interactions between NPP and GDP are greatly affected by factors of spatial location aside from human factors and natural systems' characteristics.

Regulation and investment in the U.S. telecommunications industry

Reversing a two-decade deregulatory trend of telecommunications services, in 2010 U.S. regulators embarked on an aggressive regulatory agenda including, but not limited to, the regulation of high-speed Internet services under the auspices of net neutrality using utility-style regulations codified in the 1930s. Firms, regulators, and analysts feared a reduction in capital spending, contradicting established policy goals of expanding Internet availability and adoption. In this article, a difference-in-differences regression model augmented with randomization inference is applied to government data on capital spending in telecommunications. Large negative effects on investment are found. The estimated effects are robust across changes in estimation periods and model specifications, and multiple tests of the model’s assumptions lend credibility to the findings.
