科学与技术耦合效果评价——科技互补效应和成本效应分析

考虑到当前创新环境日益复杂化，科学与技术耦合系统已成为一个受系统内外因共同影响而发生演化的开放系统。在为耦合系统构建状态空间模型的基础上，通过求解该模型，刻画科学技术化强度和技术科学化强度，据此分析科学与技术互动产生的互补效应和成本效应，评价29个省份的科学与技术耦合效果，并测度地区科技发展所属耦合路径类型。研究表明，不同省份推进科学技术化进程和技术科学化进程的差异性显著；科学与技术耦合效果最佳并不能说明地区科技发展速度最快；绝大多数省份的科技耦合路径表现为科技中立路径，占比最小的路径为技术强势路径。基于不同省份的耦合情况差异，提出针对性建议。     

Mobile diaries – Benchmark against metered measurements: An empirical investigation

Researchers seeking to study the relationships between consumers' communications, attitudes, and behaviors could benefit from monitoring consumers over time, across multiple locations and channels, and in a way that reflects consumers' subjective perceptions. Diaries on smartphones (mobile diaries) can be used as a research tool for such purposes. A mobile diary is a self-report instrument whereby people use their mobile handset to repeatedly report experiences of interest. Mobile diaries are increasingly used in psychology, geography, medicine, and commercial marketing. Yet they have rarely been used for quantitative marketing research, and were not benchmarked against best-practice metrics in marketing.In this study, we aim to set the ground for using mobile diaries in quantitative marketing research. We first lay out the theoretical infrastructure for the usage of mobile diaries, and describe possible respondent reporting concerns, including concerns related to non-reporting, reporting over time, and concerns stemming from individual-level heterogeneity.We demonstrate the potential of mobile diaries, as well as the importance of the various concerns, using a benchmark test case in the context of primetime TV viewing. Our benchmark uses a sample of respondents with both mobile diary viewing reports and Nielsen People Meter (NPM) records. Our analysis reveals that averaging across all conditions, 47.4%–64.7% of the NPM records are reported by the diary. The major sources for mismatch are random time periods without alarms, short viewings, and periodic reporting inactivity (pulsing). Concerns such as a decrease in reporting rates over time (e.g., fatigue), smartphone ownership, and demographic variation across individuals have relatively small effects on reporting likelihood. Analyzing the cases in which diary reports do not have a matching NPM record, we find many of them can be attributed to out-of-home viewing and viewing on non-metered devices. This finding demonstrates how mobile diaries can complement metered measurements. Overall, aggregate diary-based ratings have a 0.90 correlation with NPM ratings.We discuss implications for designing and using mobile diary studies in marketing.

广东湖北碳排放权市场动态相依性分析与风险测度

选择具有代表性的湖北和广东碳排放权交易市场为研究对象,利用GARCH-POT-Copula模型对这两个市场的动态相依性与组合风险度量进行分析。研究结果表明:广东和湖北碳排放权市场之间的相依度较小,两个碳排放权市场价格波动不能给对方市场带来较大的影响,两市场近似于独立存在。提出了要从配额指标、基础设施建设、报送系统、市场交易主体等方面建立健全和完善全国统一的碳排放权交易市场的建议。     

多源置信综合的雷达与ESM协同跟踪方法

跟踪空间邻近目标时，仅依靠运动学信息不足以实现可靠的数据关联，而基于动目标指示器（Moving Target Indicator，MTI）雷达和电子支援措施（Electronic Support Measurement，ESM）的多源异类传感器数据融合可以通过提升数据关联性能达到改善跟踪性能的目的。通过构建基于五种成比例再分配规则（Five Proportional Conflict Redistribution Rules，PCR5）置信度量的数据关联策略，将目标运动学信息和属性信息结合做多特征推理，解决异类传感器数据的不确定性和不一致性；利用Dempster-Shafer（DS）证据理论方法进行属性融合更新，完成属性信息在时间序列上的相干积累，实现空间邻近目标的可靠跟踪。该方法从数据关联和状态估计两方面联合进行改进，通过引入属性信息提升数据关联的正确性，从而提升跟踪性能，实现多源异类信息下的协同跟踪。仿真表明，相比于仅雷达跟踪、雷达和ESM序惯跟踪等方案，该方法可有效提升跟踪精度和关联性能。     

Can welfare be measured with a preference-satisfaction index?

Welfare in economics is generally conceived of in terms of the satisfaction of preferences, but a general, comparable index measure of welfare is generally not taken to be possible. In recent years, in response to the usage of measures of subjective well-being as indices of welfare in economics, a number of economists have started to develop measures of welfare based on preference-satisfaction. In order to evaluate the success of such measures, I formulate criteria of policy-relevance and theoretical success in the context of preference-satisfaction measures of welfare. I present a detailed case study of the methodological choices put forward in a prominent generalized proposal for measuring welfare through preferences recently published in the American Economic Review. I contrast this with an alternative welfare measure which also uses preferences to weight aspects of welfare: the ICECAP-A measure. I assess the methodology of both approaches in detail and argue that the two goals of a preference measure of welfare can only be satisfied at the expense of making a measure prohibitively costly.     

中国城镇化包容性发展中的公共投资支持影响研究

本文通过构建城镇化包容性发展指标体系，测度出中国2003—2015年30个省级区域的城镇化包容性发展指数，经莫兰指数检验发现其具有显著的空间正相关性。进而采用空间计量模型，基于户籍制度改革背景，从生产性公共投资、社会性公共投资与环保性公共投资三个方面研究公共投资对城镇化包容性发展的影响。研究结果表明，生产性公共投资与社会性公共投资对城镇化包容性发展均存在显著的正向支持作用，且户籍制度改革变量与二者产生了正向的交互作用，说明随着对人口流动限制的放松，生产性公共投资与社会性公共投资对城镇化包容性发展的支持作用有所增强，但环保性公共投资未能表现出显著的支持作用。在未来城镇化进程中，应当优化调整中国公共投资的行业结构与区域结构，从而更好地提升城镇化包容性发展水平。
