县域经济增长中结构红利的测度及决定 ——基于中国1 820个县面板数据的实证分析

产业结构升级是经济增长的源泉之一。本文基于中国1 820个县的面板数据，采用Translog生产函数估计要素弹性，进而测度县域经济增长中的结构红利，同时构建空间误差计量模型对结构红利的影响因素进行检验。研究结果表明2002-2010年间，结构红利占县域GDP总值的444%，对县域GDP增长的贡献达到了2435%。劳均资本、劳均土地等变量对结构红利有显著影响，本文还发现，在东部、中部、西部三个地区，财政支出占GDP的比重对结构红利都有显著的负向影响。     

Analysis of interregional industry linkage and economic distance in China: evidence from the mining industry

The mining industry is an important sector of the national economy, which provides essential support for energy and other resources for economic development. Industrial linkage and economic distance are two different concepts in measuring the correlationship of different industries, in this article, we apply the model that combines both of them to analyse the industries significantly influence the mining industry. We find that electricity and heating industry, and the mining industry itself from forward linkages have greatly influenced the mining industry, and the industries from backward linkages affect mining industry are changing with industrial economic transformation. We also find resources can flow across several regions only after 2007, which means the role of geographical factors limiting long-range transportation of resources is weakening after 2007. And we explain how resources flow among various regions during 1997 ~ 2007. Based on the findings above, policy implications from the empirical results obtained are discussed.     

东北地区产业升级的困境与出路

产业结构的优化升级对于推动区域经济协调发展具有重要意义。目前，东北地区的产业发展仍未摆脱结构不合理、布局趋同、国有资产负债重、企业竞争力不强的困境。制约产业结构优化升级的因素在于思想观念保守、产业融合度低和制度环境不佳。需要突破某些认识误区、优化政策环境、发展替代和后续产业。     

供给侧改革视角下的养老旅游产业发展研究--以广东省阳江市为例

供给侧结构性改革作为适应和引领经济发展新常态的重大创新,用改革的办法对错配的供需结构和扭曲的要素配置进行矫正,根据需求结构变化及时优化供给结构,实现资源优化配置和经济长期均衡发展。阳江作为滨海旅游城市,应抓住机遇,深化养老旅游产业供给侧结构性改革,优化养老旅游产业的供给结构,合理配置养老旅游资源,扩大养老旅游服务的有效供给,推进养老旅游产业的持续健康发展。     

影响失地农民再就业的原因分析与政府作为

失地农民再就业一直是党和政府着力解决的"三农"问题之一。从消除制度缺陷、提供培训资金支持、拓宽非农产业就业渠道、搞好就业培训等方面采取的措施尚未见到实效。失地农民再就业受到收入水平、生活成本、工作环境、技能要求、地区经济发展等因素的影响,政府应当在注重产业布局和调整的同时适度保留劳动密集型产业、加大公共财政保障力度,强化用人单位培训责任、系统设计失地农民权益保障制度等方面入手,破解失地农民"被城市化"后的再就业困境。     

工业锅炉煤改气客户细分模型及其应用——基于层次分析和熵权修正的模糊综合评价理论

煤改气是加快调整工业锅炉能源结构、改善大气环境质量的重要措施之一。燃气运营商欲开拓工业锅炉煤改气市场，应正确辨别终端市场客户的类别。从行业特性、企业特性、锅炉状况和客户开发潜力4个方面构建工业锅炉煤改气客户细分评价指标体系，用AHP－修正熵组合赋权方法确定评价指标权重，建立工业锅炉煤改气客户细分模型并开展应用。评价结果兼顾客观属性与主观偏好，符合客观实际，可为燃气运营商开展差异化管理，采取多元化营销模式提供决策依据。     

Spatial takeoff in the first industrial revolution

Using the framework of Desmet and Rossi-Hansberg (forthcoming), we present a model of spatial takeoff that is calibrated using spatially-disaggregated occupational data for England in c. 1710. The model predicts changes in the spatial distribution of agricultural and manufacturing employment which match data for c. 1817 and 1861. The model also matches a number of aggregate changes that characterise the first industrial revolution. Using counterfactual geographical distributions, we show that the initial concentration of productivity can matter for whether and when an industrial takeoff occurs. Subsidies to innovation in either sector can bring forward the date of takeoff while subsidies to the use of land by manufacturing firms can significantly delay a takeoff because it decreases spatial concentration of activity.
