To analyze the spatial influence mechanism of talent policy on population flow, this study compares the government work reports of 31 provinces between 2008 and 2020, and quantifies regional talent policies in nine aspects, including talent evaluation and incentives, utilizing a comprehensive, standardized, and continuous approach. Additionally, this paper develops a spatial econometric analysis model and expands on the conventional neighborhood, distance, and economic matrices by constructing a spatial weight matrix that reflects talent flow. The findings indicate that population movement exhibits spatial clustering patterns. The regional government's talent policy, primarily based on talent evaluation and incentives, positively influences population inflow. Moreover, during the implementation of talent policies, local governments demonstrate cooperative relationships. The inter-regional spillover effect between talent evaluation and talent incentives is significantly positive. In other words, a stronger local talent evaluation policy, along with robust talent incentives, encourages population inflow from neighboring provinces. However, this conclusion may vary in different regions and over time. Recently, the spatial spillover effect of population inflow and the impact of talent policies have not shown significant results. Additionally, the attractiveness of talent evaluation in the eastern region surpasses that of talent incentives, while the opposite holds true for the central and western regions. This study investigates the impact of local government talent policies on population inflow and its spatial spillover effect, offering theoretical support for intergovernmental cooperation.

Journal of Systems Science and Information 2022年第5期10卷 484-499页

作者： Xiaohong JIN Jian XU Cuihong Yang Meng HE School of Economics and Management University of Chinese Academy of SciencesBeijing 100049China Academy of Mathematics and Systems Science Chinese Academy of ScienceBeijing 100190China

Based on a questionnaire data from 553 cities in China, this study used logistic regression to examine the effects of age, education, gender, occupation, and region on intercity talent mobility.The results revealed that individuals aged 26~45 years with work experience are more willing to relocate compared with most college students or individuals with little work experience. Furthermore,individuals who have acquired a bachelor’s degree are willing to relocate, whereas those who have acquired a master’s degree and above are less willing to relocate. In addition, cities offer a higher pay and better prospects for highly qualified individuals, so mobility seems less likely happen. Moreover,intercity mobility is higher for scientific research institutions than that for other industries. Talents tend to flow from central and western cities to eastern cities. Factors determining intercity talent mobility differ from region to region. Therefore, local governments, especially in central and western cities, should actively conduct research on talent strategies while promoting the construction of the city’s regional economy;formulate scientific policies on talent mobility;promote the reasonable flow of talent;and provide an effective talent pool for urban development.

Trade Destruction and Trade Deflection:A Quasi-Natural Experiment Based on the US Additional Tariffs

引用

Journal of Systems Science & Complexity 2023年第6期36卷 2467-2496页

作者： ZHANG Yu GAO Xiang XU Ran yang cuihong yangtze Industrial Economic Institute Nanjing UniversityNanjing210093China Academy of Mathematics and Systems Science Chinese Academy of SciencesBeijing100190China School of Management Engineering Qingdao University of TechnologyQingdao266520China

This paper adopts the DID approach to investigate the trade destruction effects and trade deflection effects of the US additional tariffs.The authors find that the US additional tariffs significantly reduce China's exports of tariffed products to the US(i.e.,trade destruction effect),especially intermediate and labor-intensive products.On the other hand,they significantly increase China's exports of tariffed products to the third market(i.e.,trade deflection effect).For the$50 billion list,both the trade destruction effect and trade deflection effect are concentrated on processing exports,and the US additional tariffs significantly increase China's exports of tariffed products to ASEAN,Japan and Australia.For the$200 billion list,the US additional tariffs boost China's exports of chemicals,textiles,wood,metal products,furniture and other products to the EU,Australia,Japan,South Africa and Hong Kong,China.Furthermore,most trade deflections are not realized by lowering export prices,indicating that the trade deflections could compensate for the profit losses caused by the US additional tariffs to a certain extent.The proposed results suggest that searching for substitutions of export markets and a more open trade policy is an important way to avoid profit losses and reduce risks for enterprises and economies suffering from trade frictions.

Effects of population aging on the mortality burden of related cancers in urban and rural areas of China, 2004–2017: a population-based study

引用

Cancer Biology & Medicine 2022年第5期19卷 696-706页

作者： Yali Chen Cuihong Yang Ning Li Zixing Wang Peng Wu Jin Du Jingmei Jiang Department of Epidemiology and Biostatistics Institute of Basic Medical SciencesChinese Academy of Medical Science/School of Basic MedicinePeking Union Medical CollegeBeijing 100005China

Objective:China is a developing country with urban–rural disparities and accelerating population aging.Therefore,quantifying the effects of population aging on the cancer mortality burden is urgently needed.Methods:Using data from China’s death surveillance datasets(2004–2017),we decomposed and quantified the effects of population aging and factor variations on cancer mortality rates in urban and rural China during 2004–2017 through a decomposition method.R ratios were used to assess the extent of the mortality decreases attributable to factor variations offsetting the increases attributable to population aging for 4 aging-related cancers(lung,colorectal,esophageal,and stomach cancer).Results:Overall,population aging has led to continued increases in cancer mortality rates in China during 2004–2017(mortality rates attributable to population aging:8.63/100,000 for urban men,4.21/100,000 for urban women,11.95/100,000 for rural men,and 5.66/100,000 for rural women).The 4 cancers displayed 3 patterns.The mortality rates from lung cancer in rural China and from colorectal cancer nationwide increased because of both population aging and factor variations.Population aging was primarily responsible for the growing mortality due to lung cancer in urban areas.However,for esophageal and stomach cancer,the effect of population aging was not dominant,thus resulting in decreases in mortality rates.Conclusions:Health resource allocation should prioritize areas or cancers more adversely affected by population aging.The burden of cancer will continue to increase in the future,because of rapid population aging,but can still be offset or even reversed with enhanced cancer control and prevention.

Fault Identification for Shear-Type Structures Using Low-Frequency Vibration Modes

引用

Computer Modeling in Engineering & Sciences 2024年第3期138卷 2769-2791页

作者： cuihong Li Qiuwei yang Xi Peng School of Civil Engineering Shaoxing UniversityShaoxing312000China School of Civil and Transportation Engineering Ningbo University of TechnologyNingbo315211China Engineering Research Center of Industrial Construction in Civil Engineering of Zhejiang Ningbo University of TechnologyNingbo315211China

Shear-type structures are common structural forms in industrial and civil buildings,such as concrete and steel frame structures.Fault diagnosis of shear-type structures is an important topic to ensure the normal use of structures.The main drawback of existing damage assessment methods is that they require accurate structural finite element models for damage assessment.However,for many shear-type structures,it is difficult to obtain accurate FEM.In order to avoid finite elementmodeling,amodel-freemethod for diagnosing shear structure defects is developed in this paper.This method only needs to measure a few low-order vibration modes of the structure.The proposed defect diagnosis method is divided into two stages.In the first stage,the location of defects in the structure is determined based on the difference between the virtual displacements derived from the dynamic flexibility matrices before and after damage.In the second stage,damage severity is evaluated based on an improved frequency sensitivity equation.Themain innovations of this method lie in two aspects.The first innovation is the development of a virtual displacement difference method for determining the location of damage in the shear structure.The second is to improve the existing frequency sensitivity equation to calculate the damage degree without constructing the finite elementmodel.Thismethod has been verified on a numerical example of a 22-story shear frame structure and an experimental example of a three-story steel shear structure.Based on numerical analysis and experimental data validation,it is shown that this method only needs to use the low-order modes of structural vibration to diagnose the defect location and damage degree,and does not require finite element modeling.The proposed method should be a very simple and practical defect diagnosis technique in engineering practice.

This study reports the fabrication of a novel photothermal material formed via the physical blending of excess lauric acid(LA)and cupric acetate,followed by efficient ligand exchange.Surprisingly,the copper–LA complex exhibited a 12-fold enhancement of the molar extinction coefficient in the nearinfrared(NIR)region relative to aqueous cupric acetate.Inspired by this interesting finding,we formulated these photothermal materials into colloidally dispersed nanoparticles via a technique that combined nanoprecipitation and in situ surface polymerization for antibacterial studies.The resultant nanoparticles exhibited rapid and stable photothermal responses to NIR irradiation,with a 4-fold enhanced photothermal conversion efficiency relative to aqueous cupric acetate.Since a positively charged monomer was incorporated during in situ surface polymerization,these positively charged nanoparticles were ingested efficiently and subsequently digested by drug-resistant bacteria.By combining the LA-mediated membrane-damaging effect,copper-mediated Fenton-like reaction,as well as the photothermal effect of the copper–LA complex,a broad-spectrum,multimodal,and synergistic antibacterial effect was achieved both in vitro and in vivo,with the killing efficiency up to 99.99%for ampicillin-resistant Escherichia coli(Ampr E.coli)and 99.9999%for methicillinresistant Staphylococcus aureus(MRSA).Our newly developed nanobiocide represents a class of exceptional broad-spectrum antibacterial materials,holding great potential for treating drug-resistant infections in clinical settings.
