基于中国124个城市2001一2020年间的面板数据,结合双重差分与合成控制法,从城市产业结构角度探究了高铁经济效应差异性的作用机制。结果表明,高铁经济效应存在较强的产业结构差异,城市第一、第二和第三产业产值占比会显著影响高铁经济效应。因此,高铁对第三产业、第二产业和第一产业占比较高的城市的正经济效应逐渐减弱。进一步从直接效应和间接效应两方面对高铁经济效应产业结构差异的作用机制进行分析后发现,高铁的间接经济效应对不同城市形成了正面或负面经济影响,是导致高铁经济效应出现产业结构差异的主要原因。

In this.work we pres.nt the res.lts.of our s.udy on the phys.cal and mechanical properties.of titanium in volume. The work cons.s.ed in determining its.phys.cal and mechanical properties.under different crys.allographic s.ructures.(HCP, FCC, BCC and s.) us.ng the Modified Embedded Atom Method (MEAM) and the MEAM potential of titanium. We us.d the LAMMPs.calculation code, bas.d on clas.ical molecular dynamics. to determine the mos. s.able s.ructure of titanium, which is.the hexagonal compact s.ructure (HCP) with crys.al parameters.a = 2.952 Å and c = 4.821 Å and a cohes.on energy of -4.87 eV. This.s.ructure is.s.conded by the cubic centred s.ructure (BCC) with a lattice parameter a = 3.274 Å and a cohes.ve energy of -4.84 eV. It was.s.own that titanium can crys.allis. into a third s.ructure which is.the face-centred cubic (FCC) s.ructure with a lattice parameter a = 4.143 Å and a cohes.ve energy of -4.82 eV. The res.lts.obtained in this.s.udy were compared with the theoretical res.lts.and s.owed cons.derable agreement.
